Reports in green (checked and edited) / highlights in red / extra highlights and comments in brown / dangerous in orange / highly dangerous in pink / good and true in blue / and my comments in black. Kindly note that whenever Orange and Pink indicate Horse-shit and Horse-fart respectively, you will be told…

Italy: The WHO declared Italy free from malaria (Horse-shit) in 1970. Since then, almost all reported cases have been imported, but their number has risen steadily over the last decades. In 1997, a case of introduced malaria occurred in a rural area of Grosseto Province, the first since the eradication of malaria from Italy (Horse-shit again). This event, along with the occasional presence of Plasmodium carriers who contracted the disease in malaria-endemic areas and the ever-increasing number of immigrants from malaria-endemic countries entering Italy raises concern about the possible reappearance of malaria in certain areas – All over Italy, if you ask me! The question that needs to be asked is: Are there mosquitoes in Italy? The answer is: YES! And the conclusion is: If there are mosquitoes in Italy, then there are females among them, and therefore there is malaria and all its affiliates and products

Guardian.com.uk via Google January 2007

Sandwiched between temperate Europe and tropical Africa, Italy is on the front line of climate change and has seen a rise in tropical diseases such as malaria and encephalitis.

The Italian environmental organisation, Legambiente, reported that Italy had been declared free of malaria by the WHO in 1970 – which means shit! The WHO is no different from all the other con-dupe-scam-syndicates. It checks where it wants and examines whom it wants and declares what is suitable for it to continue to survive and thrive – but it has made a come-back. Tick-and-mosquito-borne encephalitis, a virus which attacks the nerve system, is also on the way back. While only 18 cases had been reported before 1993, 100 were reported since, mostly around Venice – Reported does not mean exact. The figures could be 10 or 100 or even 1,000 times more. Read 822: Sham-scam-con-dupe-syndicates: Child-Sponsorship, Charitable, and Aid Organisations, – out to milk the morons, fleece the fools, and relieve the naïve of the world of their money…

The director-general of Legambiente said that diseases arrived from Africa – and stayed and spread – while tropical animals and plants attack Italy’s bio-diversity. Droughts and floods are on the rise, and semi-desert areas have appeared. A third ailment, visceral leishmaniasis, carried by sand-flies and potentially fatal, has expanded rapidly. Cases in Italy have risen from 50 before 2000 to 150 a year – with the southern region of Campania a hotspot.

Of 6 sustained droughts in Italy in the last 60 years, 4 occurred from 1990 to 2007. The average temperature has increased by 0.4C in the north in 20 years and by 0.7C in the south. Ten million hectares are at risk of desertification. 20% of the fish now swimming in the Mediterranean, including barracuda, are types that have migrated from the Red Sea as water temperatures rise.

Italy's combination of sea coast, mountains, deep valleys and plains, gives rise to a rich variety of food-products, but climate change could tip the balance. Italy is at the southern edge of the globe's temperate area and that is why it has been particularly hit by the collapse of the climatic equilibrium.

France: Epidemiological data from the French National Reference Center for Imported Diseases showed that the estimated number of cases of imported malaria Horse-shit in France increased from 5,940 in 1998 to 7,127 in 1999 and 8,056 in 2000 – To them all cases are imported cases since no authority would admit to locally transmitted malaria. And what does imported really mean? Doesn’t it mean the disease is now in the country? That 3-year progression ended in 2001 when the number of estimated cases fell back to 7,223. It was due mainly to the concomitant increase in the number of people travelling to endemic zones, especially in Africa. The countries in which contamination occurred were located in tropical Africa 95%, Asia 2.2%, and Latin America 2.7%. During the 3-year period from 1998 to 2000, there were a total of 13 autochthonous cases of malaria involving patients with no history of travel to tropical areas……7,223 in 2001 are still 1,283 cases more than in 1998 and these are only the reported cases or known figures.

Autochthonous: original flora, fauna, or inhabitants of the region in which it is found.

The distribution of Plasmodium species involved in imported malaria in France was stable with 83% involving Plasmodium falciparum – the worst and most dangerous strain – 6% involving Plasmodium vivax, 6.5% involving Plasmodium ovale, and 1.3% involving Plasmodium malariae. Attacks were clinically uncomplicated in 90 to 95% of cases and severe in 2 to 5% including fatal Plasmodium falciparum malaria in 0.37 to 0.49% of cases.

Medscape-today via Google June 2007

Plasmodium falciparum malaria is a serious health hazard for travelers to malaria-endemic areas and is often diagnosed on return to the country of residence. A retrospective study was conducted of imported falciparum malaria among travelers returning to France from malaria-endemic areas from 1996 through 2003. Epidemiologic, clinical, and parasitologic data were collected by a network of 120 laboratories and factors associated with fatal falciparum malaria were identified by logistic regression analysis. During the study period, 21,888 falciparum malaria cases were reported. There were 96 deaths for a fatality-rate of 4.4 per 1,000 cases of falciparum malaria. In multivariate analysis, risk factors independently associated with death from imported malaria were older age, European origin, travel to East Africa, and absence of chemoprophylaxis. Fatal imported malaria remains rare and preventable. Pre-travel advice and malaria management and precautions should take these risk factors into account, particularly for senior travelers.

Imported malaria is increasingly reported in Europe and North America, with an estimated 30,000 cases yearly. In 2000, the countries with the highest rates of imported Horse-shit malaria were France: 8,000 cases, the UK: 2,069 cases, the USA: 1,402 cases, Italy: 986 cases, and Germany: 732 cases – All these figures are only estimates. The actual figures could be anything from ten times to a thousand times and even more. Imported Plasmodium falciparum malaria is a serious health hazard for travelers to malaria-endemic areas, owing to the potentially severe illness and high fatality rates per 1,000: France 4; Italy 6.5; the UK 8.5; the USA 13; Germany 30.4. Risk factors associated with fatal imported malaria are poorly known. Limited series have suggested that the fatality rate is significantly lower for migrants from malaria-endemic areas than for patients from areas not endemic for the disease. Antimalarial chemoprophylaxis, even incomplete or inappropriate, may also confer a degree of protection. Better knowledge of the characteristics and risk factors for fatal imported malaria might help to improve prevention and patient management. The main features of fatal imported falciparum malaria observed in France were retrospectively analyzed during 1996–2003 and compared with those for nonfatal cases.

Australia was declared malaria-free Horse-shit in 1983. However, there has been an increase in plasmodium falciparum cases since 1990. Comparison between the 6-year periods 1990-1995 and 1996-2001 showed that plasmodium falciparum had increased by 14% to 44% while plasmodium vivax decreased by 77% to 50% and one patient died – Decreased!? And only one patient died! By God and Satan! Impossible! But even if true, that was in 2001, and 8 years is a very long time! Malaria remains an important and serious parasitic disease in Australia. Significant numbers of Australian travelers take inadequate chemo-prophylaxis while visitors, mostly immigrants in detention and armed-force personnel, are additional sources of imported malaria.

I could go on and on to quote more and more countries ad infinitum. However, here are some names, or hints, on what the anopheles mosquito, or the female of the species, has come up with: Quartan malaria; Falciparum malaria; Biduoterian fever; Black-water fever; Tertian malaria…and it only takes one bite!

924: Mosquitoes and Malaria XIV – Worldwide in Brief: Mexico / California / the USA: Cases and Fatalities
29 October, 2009

Gleaned from: IRIN-News and research sites…

Mexico 2007

Malaria: Prophylaxis with chloroquine is recommended for only a small number of areas not usually visited by travelers, including the areas near the Guatemala and Belize borders in the states of Chiapas, Quintana Roo, and Tabasco; rural areas in the states of Nayarit, Oaxaca, Sinaloa; and the areas between 24°N and 28°N latitude, and 106°W and 110°W longitude, which lie in parts of Sonora, Chihuahua, and Durango. There is no malaria risk in the major resorts along the Pacific and Gulf Coasts or along the US-Mexico border. This may have been true in 2007 – I strongly doubt it, and I have my reasons. No one, and no country, can predict or dictate what or where – but this is 2009, 24 months or 730 days, later…More than ample time for the female anopheles mosquito to know what to do, and do what it has to do…

However, travelers are required to, or must, be vaccinated against the following diseases: Hepatitis A & B, Typhoid Fever, Rabies, Measles-Mumps-Rubella, and Tetanus-Diphtheria – and these are diseases that are no jokes, and are transmitted by the female anopheles mosquito or caused by, or result from, malaria…except rabies which results from (rabid) canine-bites

Canine: members of the dog family – dogs, wolves, jackals, foxes

California

Sonoma Mosquito: Sporadic locally-acquired cases occur every year and leave no doubt that malaria could easily regain a foothold. 16 Locally acquired malaria cases were reported in California. Each time, swift response by health officials and the mosquito abatement districts prevented the disease from becoming re-established. There was one large outbreak that occurred in Nevada County, where Anopheles freeborni around a Lake Vira campground bit a marine recently back from Asia and over several months transmitted the infection to more than 35 girl-scouts and other campers. The girls had already returned to their homes scattered throughout California and Nevada before their infections began to be diagnosed – Only one man or woman! Who would believe such Horse-shit? By God and Satan!

An undocumented labourer was the probable source of a similar outbreak in San Diego County that affected over 30 migrant farm-workers and local residents before it was stopped; Anopheles hermsi was the carrier. Two hurricanes that battered western Mexico in 1997 were followed by a dramatic rise in malaria along the Pacific coast. Health officials for the state of Oaxaca recorded 10,755 cases – up from 586 the year before.

The USA

The majority of malaria infections in the USA occur among persons who have travelled to areas with ongoing transmission. In the US, cases can occur through exposure to infected blood products, congenital transmission, or through mosquito-borne transmission.

Eastern Equine Encephalitis and Western Equine Encephalitis – relating to, belonging to, or affecting, horses, donkeys, and zebras – occur in the US where they cause diseases in humans and some bird species. Because of the high mortality rate, EEE and WEE are regarded as two of the most serious mosquito-borne diseases in the USA. Symptoms range from mild flu-like illness to encephalitis, coma and death. Viruses that are carried by arthropods – blood-sucking insects such as ticks, fleas, and mosquitoes are known collectively as arboviruses. Arboviruses contain RNA, exist in over 500 species, and include the viruses that cause encephalitis, yellow fever, dengue fever, and the West Nile virus. The West Nile virus was accidentally introduced into the United States in 1999 and by 2003 had spread to almost every state with over 3,000 cases in 2006 – I say: accidentally on purpose, by the original femme fatale, and today, as to the facts and figures, anyone’s guess is as good as anyone else’s

Fight the Bite – Year to Date – California West Nile Virus Website

4 WNV-fatalities were reported: Fresno 1, Los Angeles 1, Merced 1, and Stanislaus 191 human-cases from 17 counties tested positive for WNV in 2009…so far, and those were only the reported cases…

17 horses from 11 counties tested positive for WNV in 2009…so far…

497 dead birds from 36 counties tested positive for WNV in 2009

7 new WNV-positive mosquito samples were reported from the following counties: Kern 1, Los Angeles 5, and Riverside 11,054 mosquito-samples from 27 counties tested positive for WNV in 2009

422 sentinel-chickens from 23 counties tested positive for WNV in 2009…recorded cases only

9 squirrels from 7 counties tested positive for WNV in 2009…known cases only. There could be thousands of sentinel-chickens and squirrels roaming – or dead and dying – in the US with WNV and other mosquito-transmitted diseases

As of 29th September 2009, 395 human-cases had been reported nationwide in the following 32 states: Arizona 15, Arkansas 1, California 60, Colorado 51, Georgia 3, Idaho 8, Illinois 1, Indiana 3, Iowa 3, Kansas 7, Kentucky 2, Louisiana 13, Minnesota 1, Mississippi 37, Missouri 1, Montana 3, Nebraska 33, Nevada 12, New Jersey 2, New Mexico 6, New York 1, North Dakota 1, Ohio 2, Oklahoma 4, Oregon 7, Pennsylvania 2, South Carolina 3, South Dakota 14, Tennessee 2, Texas 64, Washington 25, and Wyoming 8.

Of the 395 individuals, 202 had neurotic-invasive illness encephalitis. The median age of the 395 was 53 years, range: 2-91 years; 58% were male… 12 fatalities had been reported as of 29th September: California 2, Idaho 1, Indiana 1, Mississippi 3, New Mexico 1, Texas 3, and Wyoming 1…these are known or recorded cases only. Multiply 395 by 10 at least in order to have just an idea of the situation…I would multiply 395 by 100

923: Mosquitoes and Malaria XIII – Worldwide in Brief: Pakistan / Iran / Afghanistan / Iraq / India
28 October, 2009

Malaria Policy Centre 5th October 2009

At a recent conference, Pakistan, Iran and Afghanistan formulated a joint annual action plan to lay down groundwork to fight malaria. Known as PIAMNET (Pakistan, Iran, Afghanistan Malaria Network), the organisation planned to resolve administrative issues between the three countries and drafted proposals to help mobilize resources. Their efforts were not in vain – US-AID pledged resources, particularly in the border areas of Pakistan.

The chair-person at the conference urged the three countries to utilize indigenous resources to ensure cross-border co-operation in the highly endemic district of Balochistan, a province in south-east Pakistan.

AFGHANISTAN: half the population at risk of malaria. 14 million vulnerable

IRIN-News July 2009

Stagnant water in flood-affected parts of Afghanistan is the perfect breeding ground for malaria-causing mosquitoes. According to OCHA, the January-June floods affected over 21,000 households and caused extensive damage in over 15 of the country’s 34 provinces. At least 14 provinces in the north, east and south are highly vulnerable to malaria, especially in the summer.

According to the UN-WHO, Afghanistan had the fourth largest malaria burden worldwide with an estimated annual incidence of 18 per 1,000 people in 2007. According to the Ministry of Public Health, considerable progress had been made in curbing malaria – from 626,839 cases in 2002 to around 467,000 in 2008. A fall in numbers was also reported in the first three months of 2009 compared with the same period in 2008: 49,000 patients compared to over 53,000 – Kindly note that these are figures of reported cases only. Health officials said the distribution of 1.2 million insecticide-treated bed-nets in 2008 and improved public awareness contributed to the reduction in the number of malaria patients.

Malaria affects hundreds of thousands of Afghans every year, and also acts as a major brake on economic development.

Malaria in Iraq:

Prophylaxis is recommended for Basrah province and for areas at altitudes below 1500m (4921 ft) in the provinces of Duhok, Erbil, Ninawa, Sulaimaninya…Transmission occurs chiefly from May through November. The incidence of malaria has risen in recent years, due in part to political instability. There is no malaria risk in Baghdad, Tikrit, and Ramadi. For many years, the drug of choice has been chloroquine, which is inexpensive and generally well-tolerated. Insect protection measures are essential.

Malaria: The view from India

In India, malaria has become a hidden problem – or a problem that the authorities would rather hide

Global-Post by Shailaja Neelakantan June 2009

26 people died of malaria in a single hospital in the north-eastern Indian state of Assam this winter, but as far as the government is concerned, they might as well never have existed. The district administration reported no deaths, and nobody except members of a local NGO took any notice. India has always under-reported its malaria cases – government officials admit off the record – but the scope of the hidden problem has become astounding. While the official figures state that in 2008, India had 1.5 million malaria cases, resulting in 924 deaths, the real number of deaths was much higher. A doctor who works for the Ant, a volunteer organisation that treats villagers, said the numbers were a joke, and that in Assam alone they had at least 1,500 deaths last year. He added that unless one knew the level of the disease burden how could one plan to prevent or treat it? According to non-governmental sources and some government officials who didn't want to be named, the number of malaria-related deaths in India was closer to 40,000 in 2008. I say: multiply 40,000 by 10 and that would be even less…

Indeed, the under-reporting of malaria cases is one of the main reasons that India has been unable to prevent or treat malaria cases – they could be treated, perhaps, but never prevented. It has led to an astounding absence of knowledge, even among supposedly qualified private and government health officials and workers. Few know, for instance, that malaria occurs in different topographies for different reasons and must be prevented differently in each area.

These problems are further complicated by foreign agencies such as the WHO which, under the influence of global lending agencies like the World Bank and big pharmaceutical companies, have forced India to adopt prevention methods that don't suit local conditions and to initiate huge, ill-considered projects rather than targeted ones. For example, under the National Vector-Borne Disease Control Programme, the umbrella programme for prevention and control of malaria Horse-shit the Indian government has introduced new rapid diagnostic tests, put a legion of India's version of barefoot-doctors in the field and rushed to convert to expensive Artemisinin-based Combination Therapies. None of these tools is sufficient, according to the grassroots health workers who are fighting this disease in the jungles.

922: Mosquitoes and Malaria XII – Worldwide in Brief: Saudi Arabia / Yemen / Oman / the UAE
28 October, 2009

Reports in green (checked and edited) / highlights in red / extra highlights and comments in brown / dangerous in orange / highly dangerous in pink / good and true in blue / and my comments in black. Kindly note that whenever Orange and Pink indicate Horse-shit and Horse-fart respectively, you will be told…

Saudi Arabia / Yemen March

IRIN-News 2008

An extensive Saudi-Yemeni campaign to combat malaria was begun in three Yemeni provinces near the border with Saudi Arabia, with the aim of reducing malaria in those areas.

The campaign would cover 13 districts and target areas near the Saudi-Yemeni border and parts of Tehama region. The Saudi-Yemeni partnership in combating malaria began in 2001 and National Malaria Control Programme NMCP said the two countries aim to make the peninsula malaria-free by 2015 – These people don’t know the female anopheles mosquito very well, do they? She is the veritable and original femme fatale!

In March 2007, 16,707 houses, with 48,580 rooms, inhabited by 100,803 people were sprayed thanks to a Saudi-Yemeni campaign in six border districts. Nice try, but it won’t wash because Man-the-Ape attacks the mosquitoes in 13 districts; they retreat to other districts or hide where the insecticides cannot reach. Many are the times when Man-the-Ape sprays homes and rooms with insecticides, and closes door-and-window-screens, yet wakes up the next day to find that not a few mosquitoes had survived and had their fill of blood. Man-the-Ape disperses them, they retreat and regroup; Man-the-Ape improves, they improvise; Man-the-Ape invents and/or develops new drugs, tools, strategies and methods, they develop resistance and circumvent or adapt. It’s evolution in motion otherwise what a cruel, heartless, and mindless God he must be to create such a coarse and callous creature like the mosquito…unless Satan, too, is doing his own creation – his own thing – on the side, with or without the knowledge or approval of God!

The NMCP distributed 381,138 mosquito-nets in 95 malaria-infected districts and, according to the WHO office in Yemen, some 60% of the population lives in malaria areas. Globally, malaria causes more than 5.5 million deaths annually, according to the Centers for Disease Control and in Yemen, there are around 900,000 recorded malaria cases annually and tens of thousands of people die of the disease every year. Plasmodium falciparum, a species of parasite, causes 90% of cases in Yemen and is responsible for the vast majority of deaths from malaria.

According to the Malaria Atlas Project, new research showed that high rates of population inflows from Somalia would represent a continued risk of re-introducing the parasite. There are about 800,000 African migrants in Yemen, mostly from the Horn of Africa, according to the Ministry of Interior, and more arrive daily.

Read “the Dire Plights of Others” series: 414 / 415 / 416 / 417 / 418 and 419

Medical-News-Today October 2006

Malaria is not usually thought of as a major disease in the Middle-East, but a study from Yemen revealed high levels of severe malaria in children. In fact, the figures showed that as many as 4 out of 10 children attending hospital with severe illness could be affected during the peak season – comparable to many countries in Africa.

Researchers identified over 2,000 children aged from 6 months to 10 years who were admitted to two public hospitals with suspected malaria. Malaria was confirmed in 1,332 children, 808 of whom had severe malaria.

The proportion of admissions varied according to the season, from 1% between July and September to 40% in February and March. 26 children died in hospital. Most deaths were in children with a neurological presentation, and more girls died than boys. Malaria places a high burden on health services in Yemen, say the authors. Malaria-control should be a priority and lessons should be learnt from other areas with seasonal malaria.

Oman

Beginning in April 1998, the surveillance system in Dhofar region, Oman, detected malaria cases among individuals…malaria cases were defined as unexplained fevers in residents of the Dhofar region from April to September 1998…Over a period of 7 months, 1279 patients with fever were examined for malaria parasites. 65 cases were positive for malariabut there are several other fevers like yellow fever, dengue fever, Rift-Valley fever, that are transmitted by the female anopheles mosquito

Out of the 2323 slides collected from the community and 2487 from school children, 21 slides were positive. All of them were from illegal immigrants. The entomological survey detected three vectors, previously found in the region: A. d'thali, A. sergenti and A. stephensi

Although the region is classified as a malaria-free region (Horse-shit), it has the potential for malaria introduction. That outbreak most likely occurred due to the influx of hundreds of illegal Somali immigrants into the Dhofar region due to the civil war, providing a sufficient number of gametocyte carriers for local anopheles mosquitoes to feed on and transmit…

The UAE

The Korean Journal of Parasitology May 2009

Local malaria transmission came to an end – supposedly – in 1997. Nevertheless, the UAE had been subjected to substantial importation of malaria cases from abroad, concerning both UAE nationals and immigrants from malarial countries with a total number of 2,119 cases in 2007. Plasmodium infections were identified with the genus P. vivax and P. falciparum…This simply means that malaria either has been there all the time or has returned…

The Democratic Republic of Congo (DRC): malaria still biggest killer

IRIN-News April 2008

Malaria is the primary cause of sickness, mortality, and morbidity in the country as it is in all of Africa, despite the efforts made. The secondary cause is tuberculosis. According to data, 5,000,000 cases of malaria are registered every year throughout the country with a population of nearly 60 million, and between 500,000 and 1,000,000 people die of the disease every year.

Congo-News-Channel via IRIN-News 5th October 2009

In the area of DRC's Province Orientale, malaria is endemic and nearly every child gets it.

Health experts estimate that each child under five in the DRC has 6 to 10 attacks of malaria per year. That is equivalent to as many as, or more than, 100 million episodes, annually. Approximately 180,000 Congolese children under five die from the disease every year and many others are orphaned when malaria weakens and kills their parents.

Workers loaded insecticide-treated bed-nets onto barges in Kinshasa, DRC. The nets would be transported up the Congo River for distribution to remote regions of the country. ITBNs are good and will protect people when they are asleep, but what about when they are awake? Let not anyone underestimate the female anopheles mosquito, or take her for a fool…

Congo Brazzaville: Fighting malaria in children. Climate changes accelerate vector-borne diseases

Climate changes are directly responsible for the geographic distribution of vector-borne diseases such as malaria and epidemics of meningococcal meningitis, tuberculosis, Rift-Valley fever, and cholera.

Msn-Encarta Dictionary

Meningococcal: bacterium that causes cerebrospinal meningitis; Latin Neisseria meningitides

Meningitis: a serious, oft-times fatal illness in which a viral or bacterial infection inflames the meninges, causing symptoms such as severe headaches, vomiting, stiff neck, and high fever

Meninges: the three membranes that surround and protect the brain and the spinal cord, called the dura-mater, the arachnoid-mater, and the pia-mater

Ghana

IRIN-News and other sources April 2009

Malaria is transmitted throughout all of Ghana and is responsible for more than 44% of out-patient visits and approximately 22% of deaths in children under five. It is one of 15 countries benefiting from the President’s Malaria Initiative (PMI), a five-year, $1.2 billion programme led by the US Agency for International Development – USAID – and implemented together with the Centers for Disease Control and Prevention – CDC-P.

At a glance

US Census Bureau and International Data Base 2009: Population: 23.8 million (estimated) / Life expectancy: 59 (males) 61 (females) / WHO World Malaria Report 2008: Population risk: 100% (2006) / UNICEF State of the World’s Children 2009: Mortality rate (children under 5): 115/1,000 or approximately 1 out of 9

In support of Ghana’s National Malaria Control Programme NMCP, PMI backs four key intervention strategies to prevent and treat malaria: Insecticide-treated mosquito nets (ITNs) / Indoor residual spraying with insecticides / sporadic preventive treatment for pregnant women / diagnosis of malaria and treatment with artemisinin-based combination therapy

Nigeria

Millions of deaths attributable to malaria are recorded globally. The disease constitutes a huge epidemiologic burden in Africa and continues to cripple the economic development on the continent. The disease is responsible for 60% of out-patient visits to health facilities, 30% of childhood deaths, and 11% of maternal deaths. The annual financial loss due to malaria is estimated to be about 132 billion Naira in the form of treatment costs, prevention, loss of man-hours etc; yet, it is a treatable and completely evitable disease.

Roll Back Malaria RBM in Nigeria anchors on the global strategies for malaria control which are multi-pronged and of proven efficacy: Prompt and Effective Case Management / Indoor Residual Spraying (IRS) and Environmental Management / Intermittent Preventive Treatment of malaria in pregnancy / Integrated Vector Management including Use of ITNs

Other cross-cutting interventions include Advocacy, Communication and Social Mobilization, Effective Programme Management, Monitoring, Evaluation, Partnership and Collaboration

920: Mosquitoes and Malaria X – Worldwide in Brief: Indonesia / Thailand / the Philippines / and what malaria-free really means…
25 October, 2009

IRIN-News

Indonesia: Renewed drive to eliminate malaria

Jakarta April 2008: Indonesia, where an estimated 100 million people live in areas susceptible to malaria, had embarked on a drive to eliminate the disease by 2030 – That’ll be the year! Human-Apes invent and improve – evolve – new drugs and methods, and mosquitoes change and adapt to them, and – evolve – become more resistant and resilient…evolution in motion…

In 2007, 1.75 million Indonesians were clinically diagnosed with malaria and more than 300,000 people tested positive for the disease. A clinical diagnosis involves only the observation of symptoms while positive cases are confirmed through microscopy slides or rapid diagnostic tests – Again, these figures are too pat for belief.

The fatality rate in Indonesia was estimated at about 1% but it was believed that many more deaths were not recorded, due to no access to health-services among people in remote villages.

Five provinces in eastern Indonesia had been categorized as high-endemic regions. While the islands of Java, Borneo and Sulawesi were considered low-endemic, in several areas malaria cases remained high. Under a programme launched by the health ministry, Indonesia aimed to halve the number of villages where more than 5 in 1,000 people were infected with malaria by 2010, and eliminate the disease by 2030. In some villages in the easternmost region of Papua, which consists of three provinces, between 30 and 80% of the population were infected with malaria.

Like I said before, the wily, wicked, cunning, and highly ruthless, resilient, and relentless mosquito is a creature that has learnt to migrate, change, adopt and adapt to any and all conditions, environments and circumstances. Man-the-Ape attacks, it retreats and regroups; Man-the-Ape improves, it improvises; Man-the-Ape invents and/or develops new drugs, tools, strategies and methods, it develops resistance and circumvents or adapts. I know the mosquito too well and I respect it too much to underestimate it or take it for a fool! To say that Creation is true and Evolution is false; and that God created this coarse and callous creature is…I say it evolved into what it is. It’s evolution in motion. By God and Satan!

Thailand: Winning the battle against malaria but challenges remained

Bangkok April 2008: Thailand, widely recognised as a leader in the global war or struggle against malaria, announced a 50% drop in mortality and morbidity in 2005 from 1998. The number of reported cases dropped from 192,000 in 1998 to 51,000 in 2004 JEEZ! See how exact and glib the figures were!? Even so, the WHO and Department of Public Health viewed malaria as an ongoing disease and reported a sharp rise in infections since 2004. There were more than 63,000 reported cases in 2007. According to the WHO, half of all malaria cases in Thailand were in its four southernmost provinces: Songkhla, Pattani, Yala, and Narathiwat. The other half are among migrant workers and displaced persons from Myanmar, Laos, and Cambodia along the border.

However, critical challenges stemmed from an influx of counterfeit and sub-standard anti-malarial drugs into the country. Another serious hurdle was treating artesunate-sensitive and possible artesunate-resistant malaria. There was also a risk of these strains spreading from south-east Asia to around the world. Artesunate, an extract of the artemisia annua herb, is a powerful anti-malarial therapy. Public health experts view artesunate, as part of Artemisinin-based combination therapy, as the best available treatment against multi-drug-resistant Plasmodium falciparum malaria in south-east Asia.

The Philippines: 6 provinces declared malaria-free, but 59 provinces declared the mosquitoes free to move, bite, and bestow…and malaria free to kill at will

Manila April 2008: The Department of Health marked World Malaria Day on 25th April by declaring 6 more provinces malaria-free, bringing the total to 22 out of 81. The provinces of Marinduque, Sorsogon, and Albay in Luzon; Eastern and Western Samar in the Visayas; and Surigao del Norte in Mindanao were declared malaria-free (Horse-shit) after having had no reported indigenous or local natives cases for five consecutive years. In 2006, Benguet, Cavite, and Masbate were classified malaria-free. 13 other provinces were declared free of the disease in 1999, and remain so today. Or so they say! Believe only half of what you see, and nothing of what you hear…the fact that there were no reported cases does not mean no cases at all. Thousands of the local natives have no access to official venues.  Also, the D of H could have said that only to cover its ass – after pocketing at least half of the funds allotted to the project.

Malaria cases had consistently declined from more than 76,000 reported in 1990 to 46,000 in 2005, with 150 deaths in that year. In 2006, malaria incidences declined a further 26% to 33,800, with 89 deaths. Such exact figures make me need to hold my nose…something smells

Challenges remain. The disease is still endemic in 59 provinces, with 26 Category A provinces contributing about 90% of the total reported cases. There are 10.8 million people at risk of acquiring the disease in these endemic areas and malaria still has the 9th highest morbidity rate in the country. The WHO lists the Philippines among the 10 malaria endemic countries in the Western Pacific region. Now, let’s take that half-Horse-shit and half-Horse-fart word they are so fond of using: malaria-free. Malaria-free could mean either free from malaria, which is impossible, or malaria is free to roam at will – all of you out there, and the rest in here, of my dear readers and fellow-Apes may choose…but look well, and choose well.

2009: According to the WHO, there are an estimated 109 malaria countries in 4 regions Africa, Asia Pacific, the Americas, and the Middle-East and Eurasia…see 915…but don’t be fooled, and take it from me…wherever you see mosquitoes on this doomed planet, you’d better be sure there is malaria in one strain or the other – severe, moderate, or mild – and other diseases. Also, and this is more important than you think, there is no such a disease as mild malaria. Mild is only mild when mild is recognised early, taken very seriously, and treated immediately. Fool around with mild and mild will soon show you how wild mild can be…

919: Mosquitoes and Malaria IX – Worldwide in Brief: Cambodia – How the mosquito retreats, regroups, adapts, and counter-attacks
23 October, 2009

The Mosquitoes retreat but do not surrender and they return with a vengeance…

Malaria: the invincible and often invisible killer-monster; and the mosquito: a wily, wicked, cunning, and highly ruthless, resilient, and relentless creature that has learnt to migrate, change, and adapt to any and all conditions, environments and circumstances.  To think that a kind, merciful, loving, compassionate, and all-forgiving God created it! I wonder why!

It takes just one look to fall in love; it takes just one bite to catch malaria!

Cambodia: Malaria on decline due to concerted preventive and awareness efforts

IRIN-News / Plus-News

Phnom Penh April 2008: Please sleep under the insecticide-treated nets ran the message on a large banner erected for Malaria Day on 25th April. In Cambodia, that message sank in.

Malaria, one of the world's deadliest diseases, appeared to have been on the retreat in Cambodia as the number of infections and deaths due to the disease had decreased in previous years thanks to better health education and concerted efforts at mosquito-net distribution and village-level treatments. The National Centre for Parasitology, Entomology, and Malaria Control said 100,000 malaria cases had been reported in 2006, falling to 59,000 in 2007. Although the downward trend was believed to be continuing, data for the first three months of 2008 were not yet available – Well; reported case does not mean actual cases. Officials could have registered fewer cases in order to prove their hard work and efficiency, fool the (M)asses, and please their superiors.

Preventing malaria in its early stages and treating it rapidly was the key to that supposed success; wide-scale distribution of insecticide-treated nets and providing awareness-training to village volunteers on the frontlines had also been crucial. Some 557,000 mosquito-nets were distributed free in 2007, and 1,000,000 mosquito-nets would be distributed to the neediest communities in 2008 – However, to me, these figures are too exact to be credible

Always multiply reported cases by at least 2 in order to have the closest approximate figures; you may make your own calculations.

Cambodia: New malaria strain resists potent drugs

The AP via Bloomberg.com July 2009

Malaria has become resistant to the most powerful drugs available in Southeast Asia, as the WHO races to stop the spread of the strain that could be disastrous for global malaria-control.

Treatments derived from artemisinin, the basis of the most effective anti-malaria drugs, took almost twice as long to clear the parasites that cause the disease in patients in western Cambodia as in patients in northwestern Thailand, according to a study published today in the New England Journal of Medicine.

The delay in parasite clearance times showed that the drugs are losing their power against the disease – I say the parasite has mutated, evolved, into a new, more resistant and resilient strain – in Cambodia. The failure of artemisinin-based treatments would be disastrous for global efforts aimed at curbing the mortality and morbidity wrought by the malady, said a spokesman who led the study at the Mahidol Oxford Research Unit in Bangkok.

Scientists have known for decades that Pailin, near Cambodia’s border with Thailand, is a breeding ground for drug-resistant malaria. Chloroquine and Roche Holding AG’s Fansidar began to fail there in the 1950s and 1960s, before becoming ineffective elsewhere, according to the study. The WHO, with $23 million from the Bill & Melinda Gates Foundation, has co-ordinated efforts to prevent artemisinin-resistant malaria from spreading to Africa, which has 90% of the world’s cases of the disease. Widespread artemisinin-resistant malaria would cause several more millions of deaths, without exaggeration.

918: Mosquitoes and Malaria VIII – Socio-economic effects: causes poverty more than vice versa / Diagnosis and Treatment
21 October, 2009

Socio-economic effects

Malaria is not just a disease commonly associated with poverty; it is also the cause of poverty and a major hindrance to economic development. The disease has been associated with major negative economic effects on regions where it is widespread. A comparison of average per capita GDP in 1995, adjusted to give parity of purchasing power, between malarial and non-malarial countries demonstrated a five-fold difference; moreover, in countries where malaria is common, average per capita GDP rose only 0.4% per year between 1965 and 1990, compared to 2.4% per year in other countries. However, correlation does not demonstrate causation, and the prevalence is at least partly because these regions do not have the financial capacity to prevent malaria. In its entirety, the economic impact of malaria has been estimated to cost Africa $12 billion every year. The economic impacts include costs of health care, off-work days due to sickness, days lost in education, decreased productivity due to brain damage from cerebral malaria, and loss of investment and tourism. In some countries with a heavy malaria burden, the disease may account for as much as 40% of public health expenditure, 30-50% of in-patient admissions, and up to 50% of out-patient visits.

Diagnosis and Treatment:

Since the 1600s malaria has been treated with quinine, a chemical derived from the bark of the South American cinchona tree. The tree grows on the slopes of the Andes, mainly in Peru, and it was the first effective treatment for malaria. However, it was not until 1820 that the active ingredient, quinine, was extracted from the bark, isolated, and named by the French chemists, Pierre Joseph Pelletier and Joseph Bienaimé Caventou. The drug interferes with the parasite’s development in the blood.

Chloroquine, a drug developed in the 1930s, 1940s, is more effective, safer, and cheaper than quinine. However, unfortunately, malaria parasites have developed resistance to chloroquine, rendering it useless in many parts of the world. Other anti-malarial drugs include atovaquone, mefloquine, pyrimethamine, doxycycline, and artemisinin derivatives. Malaria parasites have developed resistance to these also, necessitating a search for new drugs and for new combinations of existing drugs. Physicians increasingly prescribe a combination of drugs in treating malaria to improve their effectiveness.

In the early 20th century, before antibiotics, patients with syphilis: an infectious disease caused by spirochetes (corkscrew-shaped bacteria), treponema pallidum, and usually transmitted by sexual contact and/or kissing – were intentionally infected with malaria to create a fever. By accurately controlling the fever with quinine, the effects of both syphilis and malaria could be minimized. Some patients died from the malaria, but that was preferable to the almost-certain death from syphilis.

Artesunate: an International Non-proprietary Name, is part of the artemisinin group of drugs that treat malaria. It is a semi-synthetic derivative of artemisinin that is water-soluble and may therefore be given by injection. It is sometimes abbreviated AS.

Amodiaquine: trade names: Camoquin, Flavoquine, is a 4-aminoquinoline compound related to chloroquine, used as an anti-malarial and anti-inflammatory agent.

Amodiaquine has been shown to be more effective than chloroquine in treating chloroquine-resistant Plasmodium falciparum malaria infections and may afford more protection than chloroquine when used as weekly prophylaxis. Amodiaquine, like  , is generally well tolerated. Although licensed, the drug is not marketed in the US but is widely available in Africa. Its use, therefore, is probably more practical in long-term visitors and persons who reside in Africa.

The above drugs inhibit hemozoin bio-crystallization and thus facilitate an aggregation of cytotoxic heme; toxic-free hemes then accumulate in the parasites, leading to their deaths.

917: Mosquitoes and Malaria VII – Evolutionary pressure on human genes and other diseases it causes…
21 October, 2009

Malaria is the greatest source of selective pressure on human genomes in history. This is due to the high levels of mortality and morbidity caused by malaria, especially the P. falciparum species; below are a few of the deadly diseases that are caused directly or indirectly by malaria

Black-water fever: In malignant malaria, a large number of red blood-cells or corpuscles are destroyed. Haemoglobin (the red pigment) from the blood corpuscles is excreted in the urine, which therefore becomes dark and almost the colour of cola.

Cerebral malaria: Malignant malaria can affect the brain and the rest of the central nervous system. It is characterized by changes in the level of consciousness, convulsions, and paralysis.

Encephalitis: An infectious disease of the human central nervous system characterized by an acute inflammation of the brain, commonly caused by viral infections. It can be caused by a bacterial infection such as bacterial meningitis spreading directly to the brain (primary encephalitis), or it may be a complication of a current infectious disease like rabies or syphilis (secondary encephalitis). Certain parasitic or protozoal infestations, such as toxoplasmosis, malaria, or primary amoebic meningoencephalitis, can also cause encephalitis in people with compromised immune systems. Lyme disease may also cause encephalitis. Bartonella henselae can also lead to this. Brain-damage occurs as the inflamed brain pushes against the skull, and can lead to death, coma and/or paralysis.

Sickle-cell disease: The best-studied influence of the malaria parasite upon the human genome is the blood disease: Sickle-cell disease or sickle-cell anaemia is a blood disorder characterized by red blood-cells that assume an abnormal, rigid sickle-shape that reduces their flexibility and results in restricted movement through blood vessels, depriving downstream tissues of oxygen. The disease is chronic and lifelong: individuals are most often well, but their lives are punctuated by periodic painful attacks and a risk of various other serious complications.

Sickle-cell disease occurs, where malaria is common, but it also occurs in people of other ethnicities. This is more common in people (or their descendants) from parts of the world such as sub-Saharan Africa because those with one or two alleles of the sickle-cell disease are resistant to malaria since the sickle-red-blood-cells are not conducive to the parasites – in areas where malaria is common there is a survival value in carrying the sickle-cell genes. In other words, malaria gives you sickle-cell which makes you resistant to malaria; the difference is malaria kills you quickly and painfully – within hours or days – sickle-cell kills you slowly and painfully – over years…your choice.

Thalassaemia or Thalassemia: Another well-documented set of mutations found in the human genome associated with malaria are those involved in causing serious blood disorders known as Thalassaemia that have presumably also been selected in the course of human evolution.

Thalassaemia or Thalassemia will be the subject or topic of separate postings:

In brief:

Most species of female mosquitoes also carry the filariasis worm which is a parasite that causes a disfiguring condition often referred to as elephantiasis, characterized by a great swelling of several parts of the body – more than 60 million people live with a filariasis disability, worldwide – that 60 million was a guess at best. Viral diseases such as yellow fever and dengue fever are transmitted mostly by Aedes aegypti mosquitoes and other viral diseases like epidemic polyarthritis: any type of arthritis that involves five or more joints; an inflammation of two, three or four joints is an oligoarthritis…are transmitted by mosquitoes

Rift-Valley fever and Ross-River fever, St. Louis encephalitis, West Nile virus, La Crosse encephalitis, Japanese encephalitis, and several other encephalitis-type diseases are carried by different mosquitoes. Eastern Equine Encephalitis and Western Equine Encephalitis: relating to, or affecting, horses, donkeys, and zebras – occur in the USA where they cause diseases in humans and some bird species. EEE and WEE are regarded as two of the most serious mosquito-borne diseases in the USA because of the high mortality rate. Symptoms range from mild flu-like illness to encephalitis, coma and death. Viruses that are carried and transmitted by arthropods such as mosquitoes, ticks, and fleas are known collectively as arboviruses – viruses transmitted by blood-sucking creatures such as mosquitoes, ticks and fleas. Arboviruses contain RNA, exist in over 500 species, and include the viruses that cause encephalitis, yellow fever, and dengue fever.

Late complications: If someone with a benign form of malaria is untreated, anaemia and an enlarged spleen may develop after days. The list of diseases transmitted by mosquitoes or resulting from, or caused by, malaria is too long to include here

Msn-EncartaArthropod: animal with a hard, outer skeleton and a jointed body and limbs. Arthropods make up a phylum of invertebrates that includes insects, such as mosquitoes, fleas, ants, beetles, and butterflies; crustaceans, such as lobsters, shrimps, and crabs; and arachnids, including scorpions, spiders, and ticks. In terms of sheer numbers and the variety of niches they fill, arthropods are the most successful animals on Earth. More than one million arthropod species have been identified, more than 20 times the number of known fish, amphibian, reptile, bird, and mammal species combined. This figure is considered a low estimate of the phylum's actual size because many arthropod species have yet to be discovered and documented. Some scientists suggest the number of arthropod species in tropical forests alone may approach six to nine million. Arthropods have adapted to life on land, at sea, and in the air. They occupy an array of habitats, from scorching deserts and scalding hot springs to snow-capped mountains and frigid fjords. As plant pollinators, nutrient recyclers, and prey for other animals, they are essential members of the web of life. If all arthropods suddenly were to perish, thousands of animals and plants that depend on their services for survival would soon vanish as well. Many arthropods, including shrimps, lobsters, and crabs, are harvested as food for people throughout the world. Other arthropods provide the ingredients for fabric-dyes, wood-preservatives, and medicines. Members of one arthropod class in particular, insects, can be formidable pests, devouring crops, destroying wood structures, and spreading malaria and other life-threatening diseases – On to 918

916: Mosquitoes and Malaria VI – Causes / Symptoms – An interview with a mosquito…
21 October, 2009

Are we supposed to stop a mosquito in mid-flight or as it squats on a wall and interview it as to whether it is in the business of transmitting malaria or not?

You: Excuse me, mosquito; are you a male or a female?

Mosquito: Female, of course; otherwise I wouldn’t be here.

You: You mean, only females go into people’s homes or hover around them and bite them?

Mosquito: Yes. Males don’t bite humans or any other living breathing moving thing; only us.

You: And do you transmit malaria?

Mosquito: What do you think? What a naïve obtuse-ostrich moron! That’s what I was born to do. I can’t help it if I was born to bite and bestow. And! Not only malaria

You: If so, why haven’t you bitten me…or tried to bite me?

Mosquito: I’ve had my evening meal – I believe it was your wife. Hang around jabbering for a while longer and I’ll be only too pleased to please you. Ass-hole!

I ask you this, and I gave you the above interview, dear readers and fellow-Apes, because some people, especially doctors (Horse-farts), say that not all mosquitoes transmit malaria. That’s like saying: not all humans get pregnant and bear children – only the female of the species!

Causes: Malaria parasites

Malaria is caused by protozoan parasites of the genus Plasmodium: phylum Apicomplexa. In humans, malaria is caused by P. falciparum, P. malariae, P. ovale, P. vivax and P. knowlesi. P. falciparum is the most common cause of infection and is responsible for about 80% of all malaria cases, and is also responsible for about 90% of all deaths from malaria. Parasitic Plasmodium species also infect mammals, primates, birds, reptiles, and rodents. There have been several documented human infections with simian Apes species of malaria: P. knowlesi, P. inui, P. cynomolgi, P. simiovale, P. brazilianum, P. schwetzi and P. simium; however, with the exception of P. knowlesi, these are mostly of limited public health importance. More Horse-shit! Avian malaria kills poultry and causes serious economic losses to poultry farmers. Many bird species serve as definitive hosts for these parasites: penguins, domestic poultry, ducks, canaries, falcons, and pigeons; but is most commonly carried asymptomatically by passerine birds – perching songbirds; which form the largest order of birds, including more than half of all bird species.

Avian malaria has a worldwide distribution and is of great economic significance to the poultry industry. Organisms such as P. gallinaceum, P. durae and P. juxtanucleare cause up to 90% mortality in poultry. Incidentally, birds with avian malaria have been used for studying the pathogenesis and treatment of malaria in humans.

Symptoms of malaria in humans:

Symptoms of malaria include fever, shivering, arthralgia (joint pains), vomiting, anaemia caused by hemolysis: the destruction of red blood cells and the release of the hemoglobin they contain; hemoglobinuria: the presence of hemoglobin from red blood-cells in the urine; and convulsions. There may be the feeling of tingling in the skin, particularly with malaria caused by P. falciparum. Classical symptoms of malaria are cyclical occurrences of sudden coldness followed by rigor, fever, shivering and sweating; lasting four to six hours, occurring every two days in P. vivax and P. ovale infections; while P. malariae, P. falciparum can cause recurrent fevers every 36-48 hours or a less pronounced but almost continuous fever. For reasons that are poorly understood, but which may be related to high intracranial pressure, children with malaria frequently exhibit abnormal posturing, a sign indicating severe brain damage. Malaria has been known to cause cognitive impairments especially in children. It causes widespread anaemia during the period of rapid-brain-development, and brain-damage. This neurological damage results from cerebral malaria to which children are more vulnerable.

Severe malaria is almost exclusively caused by P. falciparum and usually attacks within 14 days after infection. Consequences of severe malaria include coma and death, or paralysis, due to brain damage if untreated, or misdiagnosed, and thereby mistreated or treated wrongly – as ordinary flu or grippe; young children and pregnant women are especially vulnerable. Splenomegaly (enlarged spleen); severe headache; cerebral ischemia (inadequate supply of blood to the brain, caused by partial or total blockage of an artery); hepatomegaly (enlarged liver); hypoglycemia (the medical condition of having an unusually low level of sugar in the blood), and hemoglobinuria with renal failure (failure of the kidneys to function fully or properly) may occur which may in turn cause black-water fever, where hemoglobin from red blood cell-lyses (the destruction of cells by disruption of the bounding membrane, allowing the cell contents to escape) leaks into the urine. Severe malaria can progress extremely rapidly and cause death within hours or days. In the most severe cases of the disease, fatality rates can exceed 20%, even with intensive care and treatment. In endemic areas, treatment is often less satisfactory and the overall fatality rate for all cases of malaria can be as high as one in ten only  10%? That’s impossible to believe. Cognitive and developmental impairments have been documented in children who have suffered from severe malaria.

Chronic malaria exists in both P. vivax and P. ovale, but not in P. falciparum. Here, the disease can relapse for months or years after exposure as latent parasites in the liver. Describing a case of malaria as cured by observing the disappearance of parasites from the bloodstream can therefore be deceptive. The longest incubation period reported for a P. falciparum infection was 30 years. Approximately one in five of P. vivax malaria cases in temperate areas involve over-wintering by hypnozoites; i.e., relapses begin a year after the mosquito-bites. On to 917

915: Mosquitoes and Malaria V – Distribution / what’s been done, what they mean, and what you should know
20 October, 2009

The Malaria Atlas Project MAP was a non-profit project funded for 5 years by the Well-come Trust, UK. It was a joint project between the Malaria Public Health & Epidemiology Group, Centre for Geographic Medicine in Kenya, and the Spatial Ecology & Epidemiology Group, University of Oxford, UK, with collaborating nodes in America and Asia Pacific Regions.

The main objective of the project was to develop a detailed model of the spatial limits of malarial Plasmodium falciparum and Plasmodium vivax on a global scale, and its endemic range. The last attempt to map malaria risks worldwide was in the 1960s. For many areas of the world this, unfortunately, still represents the best information on malaria risk. The project aimed to map and project populations at risk of malaria to provide a more contemporary and robust means to assess current and future malaria disease burdens.

The first stages of MAP were data-acquisition and archives, and would last to the end of 2008. The various mechanisms by which they had assembled the largest ever database of malaria parasite rate data were described. MAP intended to release all data collected during the project to the public domain for which permission to disseminate had been granted. The first full release of the parasite rate data had been scheduled for June 2009 to enable global searches to be comprehensive and to provide enough time for their endemicity – characteristic of area – maps to be checked, tested, and reviewed.

MAP had not long ago released the new global spatial limits of P. falciparum malaria no risk, unstable risk, and stable risk, in parallel with the publication of a detailed description of their derivation and news of project extensions into mapping the global distribution of the dominant Anopheles vectors of human malaria to the public domain.

However I, Daniel in the Lion’s Den, tell you, right here and now, and for free, too, that you cannot, and dare not, trust or rely on these statistics, since it is my belief that where there are mosquitoes, there is malaria! You see mosquitoes, and you know, or ought to know, or had better know, that where they are, so is malaria.; and there is nothing moot about that.

So long as people from malarial countries travel to and from non-malarial countries; so long as the anopheles mosquitoes, or the female of the species, exist among the mosquitoes in all countries and areas where mosquitoes are (no females = no breeding = no mosquitoes), and so long as the anopheles mosquitoes bite and drink blood indiscriminately from humans – regardless of sex, race, colour, breed, or creed, or physical condition – Anopheles does not interview its victims first, to find out whether they have malaria, encephalitis, tuberculosis, HIV/AIDS, or thalassemia or whatever; they just bite and drink; actually, they prefer victims with diseases since that is what they were made or created for: to spread diseases – and from other creatures, too: primates, mammals, rodents, birds, and reptiles – so long must you realise the risks, cast aside these imaginary and highly speculative maps and statistics, and take the necessary precautions: you swat them if and when you can; you spray them and your homes and premises, especially gardens and orchards, with insecticides, and spray yourself with mosquito-repellents; you install screens in your doors and on your windows; you sleep in mosquito-nets; you beware of where you are, especially from evening, through dusk, night, and dawn, to early morning, and make sure there are anti-mosquito mats in electric or other heaters; and you take the appropriate anti-malarial drugs regularly as prophylaxis – because prevention is better than cure, and cure is better than endure.

The problem lies in the reluctance, asininity, and refusal of medical science to face and accept the fact that, just as humans migrate, other living creatures – primates, mammals, reptiles, rodents, insects, and plants – also migrate, in one way or the other – either by themselves or by being transported by humans as food, livestock, pets, zoo-animals, show-animals (circuses), or home-decor. What I see and say or write today, you will see and hear or read much later, if not too late! By God and Satan!

NB: According to the WHO, malaria is present in the following countries all over the world, though in some countries it is restricted to specific regions and areas – kindly note that this is based on the last attempt to map malaria-risk areas worldwide in the 1960s and is therefore no longer reliable – that is, if it had ever been reliable. Also, kindly bear in mind that no map or statistics on malaria could ever be reliable, since by the time the map, and the facts and figures, have been assembled, arranged, organised, and released, most countries and areas on the map have changed, actually increased, and most of the facts and figures have become obsolete and useless.

The Middle East and Asia: Afghanistan, India, Iran, Iraq, Pakistan, Saudi Arabia, Turkey, and Yemen

Africa: Countries along the coast of Africa from Mauritania on the north-west to Egypt on the north-east: Mauritania, Senegal, Gambia, Guinea Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, Cameroon, Sao Tome & Principe, Equatorial Guinea, Gabon, Congo, Angola, Namibia, Lesotho, South Africa, Swaziland, Mozambique, Madagascar, Mauritius, Mayotte, Comoros, Tanzania, Rwanda, Kenya, Uganda, Somalia, Djibouti, Eritrea, the Sudan, and Egypt

Africa: Countries inland from Mali in the north-west to Ethiopia in the north-east: Mali, Burkina Faso, Niger, Chad, Central African Republic, Democratic Republic of Congo, Zambia, Malawi, Zimbabwe, and Botswana

Central America: Mexico, Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, and Haiti

South America: Countries from the northern to the southern part of the continent: Venezuela, Colombia, Guyana, Surinam, French Guiana, Ecuador, Brazil, Peru, Bolivia, Paraguay, and Argentina

Personally, and if all of my dear readers and fellow-Apes out there and the rest in here were to ask me, I would say: malaria exists mostly in the tropical, sub-tropical, and temperate zonesvery high risk, not so high, and high enough; and everywhere else on the planet – in one form or strain or the other; from mild to moderate to severe – where there are mosquitoes, in bulk or retail – from the north pole to the south pole, because it is a very small world, due to science and technology, and humans and animals – birds, mammals, primates, reptiles, and rodents – migrate; either voluntarily, or transported, and the wily, wicked, cunning, and highly ruthless, resilient, and relentless mosquito is a creature that has learnt to migrate, change, adopt and adapt to any and all conditions, environments, and circumstances – like Human-Apes.

914: Mosquitoes and Malaria IV – Origin / History / Discovery
20 October, 2009

Mosquitoes and Malaria IV – Origin / History / Discovery

Malaria has infected humans for more than 50,000 years and has been a human pathogen (virus, bacterium, or germ) for the entire history of our species. Indeed, close relatives of the human-malaria parasites remain common in our closest relatives: the gorilla, the chimpanzee, the bonobo: a rare black arboreal chimpanzee native to West Africa, south of the Congo River.  Latin name: Pan paniscus, the orangutan, and monkeys, as well as other primates. References to the unique periodic fevers of malaria are found throughout recorded history, beginning in 2700BC in China. The term, malaria, originates from Medieval Italian: mala aria, bad air or evil air and the disease was formerly called ague or marsh-fever, due to its association with swamps where there is stagnant water.

Scientific studies on malaria made their first significant advance when a French army-doctor, Charles Louis Alphonse Laveran (1845-1922), working at the military hospital in Constantine, Algeria, observed parasites for the first time inside the red blood-cells of people suffering from malaria and proposed that malaria was caused by protozoa; the first time protozoa were identified as causing disease. For that and other later discoveries, he was awarded the 1907 Nobel Prize for Physiology and Medicine; Protozoa were called Plasmodium by the Italian scientists, Ettore Marchiafava and Angelo Celli. A year later, Carlos Finlay, a Cuban doctor, treating patients suffering from yellow-fever in Havana, first suggested that mosquitoes were transmitting disease to and from humans. However, it was Britain's Sir Ronald Ross, working in India, who finally proved in 1898 that malaria is transmitted by mosquitoes. He did that by showing that certain mosquito species transmit malaria to birds and isolating and identifying malaria parasites from the salivary glands of mosquitoes that had fed on infected birds. Those findings were later confirmed by a medical board in 1900 and its recommendations were implemented in the health measures undertaken during the construction of the Panama Canal. That public-health work saved the lives of thousands of workers and helped develop the methods used in future public-health campaigns against this disease.

The Scotsman, Patrick Manson (1844–1922), who showed that insects are responsible for the spread of diseases such as malaria, elephantiasis, and filariasis infections such as threadworm, ringworm, guinea-worm, and roundworm in humans, also suspected (1894) that mosquitoes could transmit malaria – an association made considerably earlier in India, possibly as early as 2000BC. This hypothesis was experimentally confirmed independently by the Italian professor, Giovanni Battista Grassi, and the British physician, Ronald Ross, in 1898. Grassi showed that human malaria could only be transmitted by Anopheles mosquitoes. Ross demonstrated the existence of Plasmodium in the wall of the mid-gut and salivary glands of a Culex mosquito. For this discovery, he won the Nobel Prize in 1902 – Read the Nobel Peace-Prize, Knight-hoods, and Titles: 833.

Grassi also proposed, in 1900, the existence of an erythrocytic stage in the life-cycle; this was later confirmed by Short, Garnham, Covell, and Shute; who found Plasmodium in the human liver…For the life-cycle of Plasmodium, read: 912

Malaria is presently endemic in a broad band around the equator, in areas of the Americas, many parts of Asia, and much of Africa; however, it is in sub-Saharan Africa where 85-90% of fatalities occur. The geographic distribution of malaria within large regions is complex, and malaria-prone and malaria-free areas are often found close to each other. In drier areas, outbreaks of malaria can be predicted with reasonable accuracy by mapping rainfall. Malaria is more common in rural areas than in cities where there is little or no standing or stagnant water; this is in contrast to dengue-fever where urban areas present the greater risk. For example, the cities of Vietnam, Laos, and Cambodia are essentially malaria-free, but the disease is present in many rural regions. By contrast in Africa, malaria is present in both rural and urban areas, although the risk is lower in the larger cities. The global endemic levels of malaria have not been mapped since the 1960s. However, the UK Well-come Trust has funded the Malaria Atlas Project to rectify that, providing a more contemporary and robust means with which to assess current and future malaria disease burdens. Horse-shit! How could there be malaria in rural areas in a given country but not in cities? I ask you! On to 915

913: Mosquitoes and Malaria III: More facts and figures – Where there are mosquitoes there is malaria and other terrible diseases…
20 October, 2009

Report in green (checked and edited) / highlights in red / extra highlights and comments in brown / dangerous in orange / highly dangerous in pink / good and true in blue / and my comments in black

Say what you like, but it is my belief that, where there are mosquitoes, there is malaria; and other terrible diseases that result from this invincible and often invisible or submerged malicious monster – malaria

Malaria is a vector-borne highly infectious disease caused by protozoan parasites. It is widespread in tropical, subtropical, and temperate regions – including parts of the Americas, Asia, and Africa. Each year, there are approximately 515 million cases of malaria, killing between (not fewer than) 4 and 5.5 million people – this represents at least one death every 30 seconds; and these are reported malaria cases only; not to mention the malaria cases wrongly diagnosed and treated, or the deaths from other diseases as a result of malaria – the majority of whom are babies, young children and pregnant women in Sub-Saharan Africa. Malaria is commonly associated with poverty, but it is also a cause of poverty and a major hindrance to economic development.

Malaria is one of the most common infectious diseases and an enormous public health hazard. The disease is caused by protozoan parasites of the genus plasmodium. Only four types of the plasmodium parasites cause malaria in humans; the severest and most serious and deadly forms of the disease are caused by plasmodium falciparum and plasmodium vivax. Other related species, plasmodium ovale and plasmodium malariae can also affect humans. This group of human-pathogenic plasmodium species is usually referred to as malaria parasites. Other plasmodium species infect primates – humans are primates mammals, rodents, birds, and reptiles. Several of these species, particularly those that infect rodents, have been used in experimental studies and for testing anti-malaria drugs and vaccines. I ask you. They ought to be conducting experimental studies and tests with primates: monkeys, gorillas, and especially chimpanzees and orangutans – who are our closest relatives! By God and Satan!

Malaria parasites are transmitted by female Anopheles mosquitoes, and they multiply fast within red blood-cells, causing symptoms that include anaemia (light headedness, shortness of breath) tachycardia (abnormal rapid heart-beats), as well as other general symptoms such as high fever, headache, aches all over, chills and shivering with a high temperature (hot, yet shaking like a leaf in a storm), nausea, flu-like illness, and in severe cases, coma and death. Malaria transmission can be reduced by preventing mosquito-bites with mosquito-nets and insect-repellents, or by mosquito-control measures such as spraying insecticides inside houses and draining standing or stagnant water where female mosquitoes lay their eggs.

Although there are some under development, no vaccine is currently available for malaria; preventative and curative drugs must be taken continuously to reduce the risk of infection and complications. Prophylactic drug-treatments are often too expensive for most people living in endemic areas. Most adults from endemic areas have a degree of long-term recurrent infection and also of partial resistance; the resistance reduces with time and these adults may become susceptible to severe malaria if they have spent a significant amount of time in non-endemic areas. They are strongly recommended to take full precautions if they return to an endemic area. Malaria infections are treated through the use of anti-malarial drugs, such as quinine or Artemisinin derivatives, although drug-resistance has increased.

The blood-and-mosquito stages of the malaria life-cycle had been identified in the 19th and early 20th centuries, but it was not until the 1980s that the latent liver-form of the parasite was observed. The discovery of this latent form of the parasite finally explained why victims could appear to be have been cured of malaria but still relapse, years after the parasite had appeared to have disappeared – seemed to have disappeared – from their systems.

Co-infection with HIV and malaria cause increased mortalities, but that is less of a problem than with HIV/tuberculosis; due to the two diseases often attacking different age-ranges, with malaria being most common in the young and tuberculosis most common in the old. Although HIV/malaria produce less severe symptoms than the interaction between HIV/tb, HIV/malaria contribute to each other's spread because malaria increases the viral load and HIV increases the patient's susceptibility to malaria by reducing the patient’s immunity.

912: Mosquitoes and Malaria II: Vectors / Pathogens / Plasmodium / Discovery – the female of the species live to bite and bite to live…
20 October, 2009

Gleaned from various sources – too many to mention here

Report in green (checked and edited) / highlights in red / extra highlights and comments in brown / dangerous in orange / highly dangerous in pink / good and true in blue / and my comments in black

Just one look; that’s all it takes to fall in love. Just one bite; that’s all it takes to catch malaria

Vectors are similar to dispatch-riders, messengers, delivery-men/women, mail-men or women, postmen/women, and subpoena-servers, etc. Just as the instructions or orders, messages, food, letters, postal-packages, parcels, or subpoenas these hand over or deliver have nothing to do with them, so it is with mosquitoes; with only two very small but highly significant differences: mosquitoes do not hand over or deliver; they transmit; and they do not give a damn or care a hoot about whether the victim expects it or wants it or not…

All of the above hand over or deliver all of the above only upon orders; mosquitoes transmit out of in-born and in-bred instincts, and intentionally, too; not out of spite or hatred or malice afore-thought – or for revenge – but only because they were created so by a kind, merciful, compassionate, and all-forgiving God. Mosquitoes are born so…

The Anopheles mosquitoes or the female of the species live to bite and bite to live and produce eggs – or more female mosquitoes; plus not a few males for copulation purposes only, and the proliferation of more and more of the species – mosquitoes.

In epidemiology, Vectors are organisms that do not cause disease themselves, but that transmit infections by conveying pathogens from one host to another.

A classic example is the anopheles mosquito (the female of the species) which acts as a vector for the malaria disease by transmitting the malaria parasite plasmodium to humans. In this case the plasmodium is harmless to the mosquito, its intermediate host, but causes the malaria disease in humans, its definitive host or victim.

There are two types of vector that transmit infectious organisms to a host: mechanical and biological. Microbes do not multiply within mechanical vectors; they only physically transport and transmit microbes from host to host. In contrast, microbes must propagate within a biological vector before it can transmit the microbes. However, we are here concerned with mainly the mosquito. The mosquito is a mechanical vector and it transports and transmits malaria, encephalitis, dengue fever and yellow fever, West-Nile virus and several other terrible diseases including (this is my personal opinion) HIV-AIDS. Modern Medical Science either has not discovered this or doesn’t realise it yet; or perhaps doesn’t want to consider it; but a creature, like the female anopheles mosquito, that sucks or drinks (feeds on) Human Blood – and the blood of other mammals, birds, rodents, and reptiles – cannot help but carry and transmit what’s in the blood as well. Also, and this is very important, the female mosquito does not wait to be invited by a host, and it does not choose or discriminate – it only bites at will and it’s nothing personal…with no hard feelings.

Pathogens: Greek pathos suffering/emotion and gene to give birth to: infectious agents or germs; are biological agents that cause diseases or illnesses to their hosts. The term is most often used for agents that disrupt the normal physiology of multi-cellular animals or plants. However, pathogens can also infect unicellular organisms in all biological life-forms. There are several substrates and pathways whereby pathogens can invade a host; the principal pathways have different episodic time frames, but soil contamination has the longest and most persistent potential for harbouring pathogens.

The Human Body has many natural defences against some of the common pathogens such as Pneumocystis: a type of pneumonia associated with weakened immune systems; it is caused by the micro-organism pneumocystis carinii in the form of the human immune system and by some helpful bacteria present in the human body's normal flora. When the immune system or good bacteria is damaged in any way – such as by chemotherapy, human immunodeficiency virus (HIV) or acquired immune deficiency syndrome / acquired immunodeficiency syndrome (AIDS) or antibiotics taken to kill other pathogens pathogenic bacteria being held at bay can proliferate and cause harm to the host. Such cases are called opportunistic infections.

Some pathogens, such as the bacterium yersinia pestis – which may have caused the Black Plague the variola virus, and the malaria protozoa, have been responsible for massive numbers of casualties or deaths and have had numerous effects on afflicted groups. Of particular note in modern times are HIV/AIDS, which has infected several million humans globally, and Severe Acute Respiratory Syndrome (SARS) and the Influenza virus Avian flu or Bird flu. Today, while many medical advances have been made to protect against infections by pathogens, through vaccination, antibiotics, and fungicide, pathogens continue to threaten human life. Social advances such as food-safety, hygiene, and water-treatments have reduced the threat from some pathogens – but the problem is, they mutate – or evolve – and adapt, and become more resistant and resilient. It’s evolution in motion.

Plasmodium: macroscopic forms of protists – organisms belonging in an older classification system to the kingdom Protista that include protozoans, bacteria, and single-celled algae and fungi known as slime-mould. They are genus of parasitic protozoa. Infection with this genus is known as malaria. The parasite has only two hosts in its lifecycle: a female mosquito-vector and a vertebrate host. Out of the 125 malaria species of Plasmodium, only four species infect humans. Other species infect other animals, including birds, reptiles and rodents. Horse-shit! Are we to believe that, if a female anopheles mosquito that has bitten an infected bird, reptile, or rodent, bites a human, there will be no infection and no effect whatsoever? SHEESH!

The genus Plasmodium was discovered by Marcia & Celli in 1885. So far, only over 200 species have been recognised. New species continue to be discovered, described, and named – this means that new species continue to evolve or mutate from previous ones – and this proves beyond the shadow of a doubt that evolution is true and creation is false.

The genus is currently (2006) strongly in need of re-organisation and reclassification as it has been shown that parasites belonging to the genera Haemocystis and Hepatocystis appear to be closely related to Plasmodium. It is likely that other species such as Haemoproteus meleagridis will be included in this genus once it is revised.

The life-cycle of Plasmodium is very complex. It was discovered by Ronald Ross, the British physician, who worked with species from the genus Culex.

Life-cycle: Sporozoites (small, infectious and motile capable of independent movement) stages in the life of sporozoans produced by sporogony (usually within a host, from the saliva of a female mosquito) are transmitted into either the blood or the lymphatic system of the recipient. The sporozoites then migrate to the liver and invade hepatocytes. This dormant stage of the Plasmodium sporozoite in the liver is called hypnozoite.

The development from the hepatic stages to the erythrocytic stages has until very recently been obscure. In 2006, it was shown that the parasites sprout from the hepatocytes in merosomes containing hundreds or thousands of merozoites. These merosomes have been subsequently shown to lodge in the pulmonary capillaries and to slowly disintegrate there over 48-72 hours releasing merozoites. Erythrocyte invasion is increased when blood flow is slow and the cells are tightly packed: both of these conditions are found in the alveolar, air sacs or capillaries in the lungs, extremely narrow thin-walled blood vessels that connect small arteries or arterioles with small veins to form a network throughout the body…On to 913

911: Mosquitoes and Malaria I: The Mosquito is the most dangerous creature to Human-Apes; next to Human-Apes themselves.
20 October, 2009

Gleaned from: Google / Msn-Encarta-Encyclopaedia and several other sources

Report in green (checked and edited) / highlights in red / extra highlights and comments in brown / dangerous in orange / highly dangerous in pink / good and true in blue / and my comments in black

The Mosquito is the most dangerous creature to all life-forms, and especially to Human-Apes; next to Human-Apes themselves; and Malaria is to Mosquitoes what drunk is to drink, what dream is to sleep, what babies are to marriage, what pregnancy and venereal disease are to fornication without protection, what cars are to accidents, what die is to kill, what death is to birth, etc, and so forth and so on…down to what shit is to eat

Introduction: The Mosquito or Mosquitoes

Mosquitoes are insects that make up the family Culicidae. They’ve got a pair of scaled wings, a pair of halters, a slender body, and long legs. The femalesanopheles – of all mosquito species suck blood from other animals, which has made them the most deadly disease vectors known to Human-Apes; killing billions of people over thousands of years and continuing to infect hundreds of millions, and kill millions every year by the spread of diseases.

Their lengths vary, but they are rarely longer than 16mm and weigh up to 2.5mg. A female mosquito can fly, non-stop, for 1 to 4 hours at up to 1–2 km/h; covering up to 10km in a night. Most species are either nocturnal (night) or crepuscular (dawn and dusk) feeders. During the heat of the day, mosquitoes rest in a cool dark place and wait for the evenings. They may still bite if disturbed.

Mosquitoes of the genera Culex, Anopheles, Culiceta, Mansonia and Aedes are vectors. The currently known vectors for human malaria (>100 species) all belong to the genus Anopheles. Bird-malaria is commonly carried by species belonging to the genus Culex. Only female anopheles mosquitoes bite. Both sexes live on nectar, but one or more blood meals per day are needed by the females. The Females do not require blood for survival; they need supplemental substances like protein and iron – which is very low in nectar – for the development and the laying of eggs. The Toxorhynchites species of mosquitoes do not drink blood and include the largest genus of the extant mosquitoes, the larvae of which are predatory on the larvae of other mosquitoes. These mosquito-eaters have been used in the past as mosquito-control agents with varying success.

Female Anopheles Mosquitoes hunt their hosts or victims by detecting CO2 from a distance. They can also pick up on the infra-red heat emitted by the victim indicating the host is a warm blooded animal.

In their life cycles, mosquitoes undergo complete metamorphosis; going through four distinct stages: eggs, larvae, pupae, and adults; first observed and described by Aristotle.

Female mosquitoes lay their eggs one at a time or together in rafts of a hundred or more on the surface of mostly stagnant water. Anopheles and Aedes mosquitoes do not make egg-rafts but lay their eggs separately. Culex, Culiseta, and Anopheles lay their eggs on water; Aedes lay their eggs on damp soil that is periodically flooded by water. Most eggs hatch into larvae in about 48 hours. A female mosquito may lay a raft of eggs every third night during its life span – if it can find enough blood to develop the eggs. Standing water, or stagnant water, is mostly where mosquitoes breed and malaria flourishes.

In Spanish, the word Mosquito or little-fly dates back to about 1572; the word was adopted to replace the term biting-fly; to prevent confusion with the house-fly, another highly dangerous creature to Human-Apes and all living moving breathing life-forms, although not quite as dangerous as the mosquito.

Mosquitoes versus Human-Apes

Mosquitoes are vector agents that carry disease-causing viruses and parasites from person to person, or from animal to animal without catching the disease themselves. Female mosquitoes suck blood from people and other animals as part of their eating and breeding habits. When a female mosquito bites and sucks or drinks blood from her victim, she also injects saliva and anti-coagulants into the blood which contain disease-causing viruses and parasites. This vicious cycle can be interrupted by killing the mosquitoes, isolating infected people from all mosquitoes, or vaccinating the exposed population. All three techniques have been used, most often in combination, to control mosquito-transmitted diseases, but to no avail, because the mosquito is not only the most dangerous creature to Human-Apes and all living, breathing, moving life-forms, but also the wiliest and most resilient. Window screens, introduced in the 1880s, were called the most humane invention and contribution scientists have ever made to the preservation of health, sanity, and good temper.

Mosquitoes have transmitted diseases to billions of people annually in Africa, South America, Central America, Mexico and much of Asia – causing millions of deaths. In Europe, Russia, Greenland, Canada, the United States, Australia, New Zealand, Japan and other developed countries in temperate zones, mosquito-bites are now mostly an irritating nuisance; but still cause some deaths each year. Historically, before mosquito-transmitted diseases were brought under control, they caused hundreds of thousands of infections and deaths.

Mosquitoes were shown to be the method by which yellow fever and malaria were transmitted from person to person, first in Cuba, and then around the Panama Canal in the early 1900s. Since then other diseases have been shown to be transmitted the same way, and by the same highly dangerous, obnoxious, evasive, and resilient culprits.

The female-mosquito genus, Anopheles, carries the malaria parasite – see plasmodium: 912. Malaria is a leading cause of premature deaths worldwide, particularly in children under the age of 5, more than 5.5 million deaths annually, according to the Centers for Disease Control. Some species of the mosquito carry the filariasis-worm, a parasite that causes a disfiguring condition often referred to as elephantiasis, characterized by a great swelling of several parts of the body; worldwide, more than 40 million people are living with a filariasis disability. The viral diseases, yellow fever and dengue fever, are transmitted mostly by Aedes-aegypti mosquitoes. Other viral diseases like epidemic polyarthritis, Rift Valley fever, Ross River Fever, St. Louis encephalitis, West Nile virus, Japanese encephalitis, La Crosse encephalitis, and several other encephalitis-type diseases are carried by several different mosquitoes. Eastern Equine Encephalitis and Western Equine Encephalitis: relating to, belonging to, or affecting, horses, donkeys, and zebras – occur in the US where they cause diseases in humans and some bird species. Because of the high mortality rate, EEE and WEE are regarded as two of the most serious mosquito-borne diseases in the United States. Symptoms range from mild flu-like illness to encephalitis, coma, and death. Viruses that are carried by arthropods such as mosquitoes and ticks are known collectively as arboviruses – transmitted by bloodsucking creatures such as mosquitoes, ticks, and fleas. Arboviruses contain RNA, exist in over 500 species, and include the viruses that cause encephalitis, yellow fever, and dengue fever. The West Nile virus was accidentally introduced into the US in 1999 and by 2003 had spread to almost every state with over 3,000 cases in 2006. Today, as to the figure, anyone’s guess is as good as anyone else’s.

Only female mosquitoes feed on blood, thus males do not transmit the disease. The females or Anopheles genus of mosquitoes prefer to feed at night. They usually start searching for a meal in the evening and at dusk, and will continue throughout the night to dawn or early morning. Malaria parasites can also be transmitted by blood transfusions, although this is rare.

The female mosquito's period of feeding is most often undetected since the bite only becomes apparent because of the immune reaction it provokes. When a female mosquito bites a human, she injects saliva and anti-coagulants that contain plasmodiums. For any given individual, with the initial bite there is no reaction but with subsequent bites the body's immune system develops antibodies and the bite becomes inflamed and itchy within 24 hours. This is the usual reaction in young children. With more bites, the sensitivity of the human immune system increases, and an itchy red hive appears in minutes where the immune response has broken capillary blood vessels and fluid has collected under the skin. This type of reaction is common in older children and adults. Some adults can become desensitized to mosquitoes and have little or no reaction to their bites, while others can become hyper-sensitive with bites causing blistering, bruising, and large inflammatory reactions, a response known as Skeeter or Mosquito Syndrome…On to 912
