Malaria accounts for a large part of the disease burden of tropical countries, causing over a million deaths a year, mainly in African children. There are an estimated 300-500 million episodes of acute illness annually, in over 100 countries inhabited by 40 % of the World’s population. As human malaria is normally transmitted by female Anopheles Mosquitoes many methods have been developed for Malaria Vector Mosquito
TRANSMISSION OF MALARIA
Malaria is transmitted through an infected female Anopheles mosquito bite. Malarial parasites enter the blood stream, from where they enter the Liver.
It is here in the Liver Cells, that they multiply without symptoms Malarial Parasites spread from the liver cells and enter the blood stream and further multiply again.
It is further spread when another mosquito feeds on the infected person and the cycle is repeated.
Typically, malaria symptoms are intermittent fever, headache, body pain, shivering etc.
Mosquito Bed nets have been around for at least 10 decades. The consumption and use of Treated Bed Nets have increased in the last decade. This is mainly due to the increase in the awareness amongst people which have been brought in by WHO.
NEED FOR BED NETS
There are a variety of processes for making Treated Bed Nets, impregnation, Coating and Fusion. What was new was the addition of insecticide to those nets: the development of insecticide-treated bed nets provided a means to protect people throughout the night.
Insecticide treated mosquito nets effectively reduce malaria morbidity and mortality in many different epidemiological settings. Their use may not only benefit the people who are actually sleeping under them, but when used by the majority of the community, people who sleep without treated nets may also receive fewer infective bites.
