Chagas disease

Note: The acute form of Chagas disease lasts for several weeks to months and is marked by mild symptoms (such as fever, fatigue, or swelling at the infection site) or rarely by serious symptoms (such as myocarditis or meningoencephalitis) but is often asymptomatic. The acute form may sometimes progress years later to a chronic form characterized especially by cardiac and gastrointestinal complications (such as cardiomyopathy, irregular heart rhythm, and enlargement of the colon or esophagus).
