malaria is an infectious disease caused by a parasite (of the genus Plasmodium) and spread mostly by a particular mosquito (Anopheles). The saliva from the bite of the infected female mosquito infects the blood which carries the parasite to the liver where it matures.

The disease is common in tropical areas of Asia, Africa, and the Americas since these have a favorable environment for the mosquito; mortality rates in severe cases are about one in five. Estimated deaths approximate a million a year, most of which are children.

The disease is preventable and treatable through medication; preventative measures include mosquito control techniques.
