Chagas Disease, known as Kissing Bug Disease, now Endemic in the United States of America

On a humid evening in rural Texas, Maria Hernández tucks her children into bed, careful to check the corners of the bedroom for the tiny insects’ locals call chinches. For generations, these “kissing bugs” were thought of as little more than a nuisance-bloodsuckers that left itchy welts. But scientists now warn that the bite of these insects carries far more than irritation. Behind their ordinary appearance lurks a parasite, Trypanosoma cruzi, the cause of Chagas disease, a potentially devastating illness once thought to belong mostly to Latin America.

Chagas disease is an infectious disease caused by a parasite found in the faeces of the triatomine bug. Chagas disease is common in places where the triatomine bug transmits the parasite Trypanosoma cruzi. These places include South America, Central America and Mexico. The disease can be mild, causing swelling and fever, or it can be long lasting. Left untreated, it can cause congestive heart failure. Treatment for Chagas disease focuses on taking medication that kills the parasite and on managing symptoms.

Researchers now confirm that Chagas is no longer just an imported concern, it has quietly taken root in the southern United States. The disease, transmitted through the feces of kissing bugs, can smolder undetected in the body for years. While it may begin like the flu, the consequences can be brutal: irreversible heart damage, enlarged intestines, and in some cases, sudden death. Families who never left U.S. soil are now living with a disease once tied to distant borders.
