Malaria is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans (a type of unicellular microorganism) of the genus Plasmodium. Commonly, the disease is transmitted by a bite from an infected female Anopheles mosquito, which introduces the organisms from its saliva into a person’s circulatory system. In the blood, the parasites travel to the liver to mature and reproduce. Malaria causes symptoms that typically include fever and headache, which in severe cases can progress to coma or death.
There were an estimated 207 million cases of malaria in 2012, causing over 600 000 deaths. Malaria transmission occurs in 97 countries and territories around the world, inflicting the heaviest toll on countries of sub-Saharan Africa.
