Chagas disease

Abstract

Chagas disease is a parasite infection primarily transmitted to humans via the bite of triatomine insect vectors. Up to 8 million people are estimated to be infected with Chagas disease in the Americas. Patients who do not receive treatment can develop severe cardiac debility, gastrointestinal organ dysfunction, and may die. The changing demographics of the United States, a consequence of changing immigration patterns, means that healthcare providers are more likely to encounter patients with Chagas disease, and must understand its cause, pathogenesis, diagnosis, and treatment.
