Malaria is spread by the bite of an infected Anopheles mosquito. With certain malaria species, dormant forms can be produced which may cause relapses of malaria months to years later. Malaria may also be transmitted by transfusion of blood from infected people or by the use of contaminated needles or syringes.
The most common forms of human malaria are caused by Plasmodium falciparum, P. vivax, P. knowlesi, and P. malariae. P. falciparum, common in sub-Saharan Africa, and P. knowlesi, common in Southeast Asia, are especially dangerous.lasmodium, commonly known as the malaria parasite, is a large genus of parasitic protozoa. As with some other genera of clinically important microorganisms, the genus name also yields a common noun; thus species of the genus are known as plasmodia.
