American trypanosomiasis (Chagasí disease) is produced by Trypanosoma cruzi, which is transmitted to humans by the bite of an infected reduviid bug. After multiplication, the tissues most likely to be affected in the chronic stage of the disease are the cardiac muscle fibers and the digestive tract. A diffuse interstitial fibrosis of the myocardium results and may lead to heart failure and death. The inflammatory lesions in the digestive tract that are seen in the esophagus and colon produce considerable dilatation. Chagasí disease has not been an important disease in the United States; most cases have been imported, although there are a few reports of endogenous disease in the southern United States.
