T.<unk>  transmission has been documented in the Southwestern U.S., and warming trends may allow vector species to move north. U.S. domestic and wild animals are reservoirs for T.<unk> . Triatomine species in the southern U.S. have taken human blood meals, but because triatomines do not favor typical U.S. housing, risk to the U.S. population is very low. Chagas' disease's geographical occurrence happens worldwide but high-risk individuals include those who don't have access to proper housing. Its reservoir is in wild animals but its vector is a kissing bug. This is a contagious disease and can be transmitted through a number of ways: congenital transmission, blood transfusion, organ transplantation, consumption of uncooked food that has been contaminated with feces from infected bugs, and accidental laboratory exposure. Over 130 species can transmit this parasite Six taxonomic subunits are recognised.
