Likely autochthonous transmission of Trypanosoma cruzi to humans, South Central Texas, USA

Abstract

Chagas disease, caused by Trypanosoma cruzi, is a major neglected tropical disease affecting the Americas. The epi­demiology of this disease in the United States is incomplete. We report evidence of likely autochthonous vectorborne transmission of T. cruzi and health outcomes in T. cruzi–seropositive blood donors in south central Texas, USA.
