Chagas Disease is endemic throughout much of Mexico, Central America, and South America where an estimated > 8 to 11 million people are infected by the protozoan parasite Trypanosoma cruzi.
Infection occurs through vectorborne transmission via the feces of the triatomine insect (reduviid bug, kissing bug, assassin bug, and vincucha bug), which may be inadvertently inoculated into the skin or the mucosa of the eyes, nose, or mouth when the insect’s bite is scratched and rubbed.
The triatomine bug thrives under poor housing conditions (for example, mud walls, thatched roofs), so in endemic countries, people living in rural areas are at greatest risk for acquiring an infection. In rural Argentina, villagers speak of "muerte subita" or rapid death caused by Chagas.
But one Argentinian physician, Dr. Gustavo Farrugia, and his colleagues are trying to stop it.
