Malaria is caused by the parasitic protozoan Plasmodium. It is a vector-borne disease which is transmitted from person to person via bites from infected mosquitoes. Following a mosquito bite the parasites multiply in the liver and subsequently infect red blood cells.
People living in the poorest countries are the most vulnerable. The disease causes a number of non-specific symptoms including fever, headache, and vomiting. Left untreated, the disease can cause severe complications and death.
Control measures include use of insecticide-treated bednets and indoor residual spraying with insecticide – both of these methods target the mosquito vector.
Malaria is usually treated with antimalarial drugs (e.g, artemisinin-based combination therapies, ACTs). However, in many parts of the world the parasites have developed resistance to certain antimalarials.
