Malaria is a tropical disease caused by infection of the human liver and red cells by Plasmodium, a protozoan parasite which is transmitted to humans by a bite from the female Anopheles mosquito.

Anopheles mosquito: this mosquito acts as a carrier of malaria. When the mosquito bites a victim, it delivers malaria to the host.

Malaria is thought to have originated in Africa. Almost 85% of the world's malaria occurs in sub-Saharan Africa. It has spread through the Mediterranean, Southeast Asia and India by human migration and can be found in all tropical and some temperate regions. Approximately one million death occur among the children in Africa, especially those in rural area where access to medical treatments are not readily available.
