What is Chagas Disease?

Nov. 24, 2024

A recent study shows that Trypanosoma cruzi—the parasite that causes Chagas disease—can survive in dead kissing bugs (Triatominae) even within insecticide-treated dog kennels.

About Chagas Disease:

  • Chagas (CHAH-gus) disease is an inflammatory, infectious disease caused by the protozoan parasite, Trypanosoma cruzi. 
  • This parasite is found in the feces of the triatomine (reduviid) bug.
  • This bug is also known as the "kissing bug."
  • Chagas disease is common in South America, Central America, and Mexico, the primary home of the triatomine bug.
  • Also called American trypanosomiasis, Chagas disease can infect anyone. Left untreated, Chagas disease later can cause serious heart and digestive problems.
  • Treatment: 
  • During the acute phase of infection, treatment of Chagas disease focuses on killing the parasite. 
  • In people who have chronic Chagas disease, it's no longer possible to kill the parasite. Treatment in this later phase is about managing signs and symptoms.
