The U.S. Centers for Disease Control and Prevention (CDC) has declared Chagas disease endemic to the United States, meaning that it is consistently present in the country. The disease is transmitted to humans and animals, including cats and dogs, through the feces of blood-sucking kissing bugs. After biting its victim, the bug’s feces deposit the parasite that causes the disease.

The CDC reports that kissing bugs are native to the Southern U.S., but they have been found in 32 states. Chagas disease, which may initially show no symptoms, is a potentially fatal illness that can lead to chronic conditions such as heart failure, an enlarged heart or an enlarged colon. The CDC’s endemic declaration should increase awareness of Chagas disease among doctors and veterinarians, leading to more diagnoses and reporting. The declaration also paves the way for more research investment into improved diagnostics, treatments and prevention
