Tropical Parasite Spreads and Takes Hold in the US, Particularly in Texas

The Centers for Disease Control and Prevention (CDC) warns that a tropical disease called leishmaniasis, once seen mainly in Americans returning from travel abroad, now has a unique U.S. strain. The disease, spread by sandflies, could thrive in the U.S. due to improved climatic conditions. Researchers also highlight the risk of a deadlier form of the disease, visceral leishmaniasis, which can be transmitted by imported dogs carrying the parasite. Climate change and inadequate screening contribute to the spread of the disease, which can cause disfiguring skin ulcers. The U.S. lacks federal reporting on the disease, making it difficult to track its prevalence.
