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 100types 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.
Treatment aims to eliminate the Plasmodium parasite from the bloodstream.
Prevention
There are several ways to keep malaria at bay.
Vaccination
Research to develop safe and effective global vaccines for malaria is ongoing, with the licensing of one vaccine already having occurred in Europe. No vaccine is yet licensed in the U.S.
Seek medical attention for suspected symptoms of malaria as early as possible.
Advice for travelers
While malaria is not endemic to the U.S., travel to many countries around the world entails a risk.
The Centers for Disease Control advise travelers to take the following precautions:
find out what the risk of malaria is in the country and city or region they are visitingask their doctor what medications they should use to prevent infection in that regionobtain antimalarial drugs before leaving home, to avoid the risk of buying counterfeit drugs while abroadconsider the risk for individual travelers, including children, older people, pregnant women, and the existing medical conditions of any travelers
