Chagas disease, a deadly infection spread by kissing bugs, is becoming increasingly prevalent in the southern U.S. Researchers found evidence of the parasite in humans, animals, and kissing bugs across several states, indicating a persistent, though low-level, presence. This 'endemic' status, while not widespread, means the disease requires better tracking and treatment. Untreated, Chagas can cause serious heart problems and even death. Currently, the disease isn't always reported, hindering effective management and awareness.
