CFS

Chagas disease An infectious disease found in Central and South America caused by the parasite Trypanosoma cruzi. The parasite can be transmitted through bites from bugs that carry it (known as kissing bugs) or via blood transfusion. Soon after infection, there may be symptoms such as swelling of the eye on one side of the face, usually at the bite wound, but many people do not become ill until many years after being infected. Infants and persons with immunodeficiency are at risk of severe infections and complications such as meningitis and heart failure. Also known as American trypanosomiasis. See also kissing bugs.
