Chagas (CHAH-gus) disease is an inflammatory, infectious disease caused by the parasite Trypanosoma cruzi, which is found in the feces of the triatomine (reduviid) bug. Chagas disease is common in South America, Central America and Mexico, the primary home of the triatomine bug. Rare cases of Chagas disease have been found in the southern United States, as well.
Also called American trypanosomiasis, Chagas disease can infect anyone. Left untreated, Chagas disease later can cause serious heart and digestive problems.
Treatment of Chagas disease focuses on killing the parasite in acute infection and managing signs and symptoms in later stages. You can take steps to prevent the infection, too.
