Chagas disease, or American trypanosomiasis, is an endemic zoonosis that is prevalent throughout Central America and South America, and 16 to 18 million individuals are now estimated to be infected.1
Trypanosoma cruzi is a flagellated protozoan, a parasite that reproduces in tissue by multiple progressive binary fission, undergoing a nonflagellated amastigote form. The parasite is transmitted by the bites or feces of Triatominae (commonly known as conenose bugs, "vinchucas," or "barbeiros") or, less frequently, via the placenta, blood transfusion, mother's milk, or transplantation.2
