Chagas Disease, an Endemic Disease in the United States.

ABSTRACT: Chagas disease, caused by Trypanosoma cruzi parasites, is considered endemic to 21 countries in the Americas, excluding the United States. However, increasing evidence of T. cruzi parasites in the United States in triatomine insects, domestic animals, wildlife, and humans challenges that nonendemic label. Several triatomine species are common in the southern United States, where they transmit T. cruzi and invade human dwellings. Wildlife, captive animals, and companion animals, especially dogs, are commonly infected with T. cruzi parasites in this region and serve as reservoirs. Autochthonous human cases have been reported in 8 states, most notably in Texas. Labeling the United States as non-Chagas disease-endemic perpetuates low awareness and underreporting.
