Kissing bugs carry a parasite called Trypanosoma Cruzi, which causes The Chagas Disease. It's an illness that attacks the heart and digestive system, sometimes decades after the initial bug bite. Chagas disease is a serious concern, especially in areas where kissing bugs are prevalent. - Kissing Bug Bites: Kissing bugs, also known as Triatomine Bugs, transmit the parasite Trypanosoma Cruzi through their feces, which enters the body through the bite wound and mucous membranes.
