Malaria is a serious infection. It is common in tropical countries such as parts of Africa, Asia and South America. Malaria is a disease caused by a parasite called Plasmodium that lives in mosquitoes.
Globally, the World Health Organization estimates that in 2013, 198 million clinical cases of malaria occurred, and 500,000 people died of malaria, most of them children in Africa. Because malaria causes so much illness and death, the disease is a great drain on many national economies.. falciparum is the type of malaria that is most likely to result in severe infections and if not promptly treated, may lead to death. Although malaria can be a deadly disease, illness and death from malaria can usually be prevented. About 1,500 cases of malaria are diagnosed in the United States each year.
