Malaria

Malaria is a serious disease that spreads when you’re bitten by a mosquito infected by Plasmodium parasites. When it bites, the mosquito injects malaria parasites into your bloodstream.

Malaria is common in tropical areas where it’s hot and humid. Most cases happen in Africa and South Asia. It’s rare in the U.S.

Without treatment, malaria can cause brain damage, organ failure and death. See a healthcare provider right away if you live in or have traveled to an area where malaria spreads and you have symptoms.
