Malaria is a life-threatening mosquito-borne blood disease. The Anopheles mosquito transmits it to humans
The parasites in mosquitos that spread malaria belong to the Plasmodium genus. Over 100 types of Plasmodium parasite can infect a variety of species. Different types replicate at different rates, changing how quickly the symptoms escalate, and the severity of the disease.
Five types of Plasmodium parasite can infect humans. These occur in different parts of the world. Some cause a more severe type of malaria than others.
Once an infected mosquito bites a human, the parasites multiply in the host’s liver before infecting and destroying red blood cells.
In some places, early diagnosis can help treat and control malaria. However, some countries lack the resources to carry out effective screening.
Currently, no vaccine is available for use in the United States, although one vaccine has a license in Europe.
In the early 1950s, advances in treatment eliminated malaria from the U.S. However, between 1,500 and 2,000 cases still occur each year, mostly in those who have recently traveled to malaria-endemic areas.
