The mosquito injects you with an anticoagulant when she feeds. The parasites are injected along with the anticoagulant. Then, they go to the liver, where they develop and are eventually released into the blood stream, infecting red blood cells. They sit in red blood cells and multiply, periodically releasing gametocytes. These gametocytes are then picked up by still other mosquitoes during subsequent bites, and the cycle starts over again.
Malaria is found in many different parts of the world, but is mainly a prob-lem in tropical areas.
Adding to the problem, some species of malaria parasites have developed resistance to many of the drugs taken to control or cure the disease. Although HIV gets more publicity, malaria is the number one health problem in the developing world. Malaria can be prevented in several ways. The best way is to avoid getting bitten by mosquitoes in the first place. There is also an insecticide spray which, when applied to outer garments, can effectively prevent the little buggers from biting through your clothing.
