Low Trypanosoma cruzi transmission risk to humans in the trans-Pecos region of Texas

Abstract In the Trans-Pecos region of Texas, reports of domestic triatomine bites were common (67%), with 36% of residentially collected triatomines positive for Trypanosoma cruzi. Despite the transmission potential, no human infections were detected. Collected Triatoma rubida species were frequently themselves parasitized with mites.
