Emerging Tropical Disease in Mainland U.S. Raises Concerns over Vaccine Availability
Leishmaniasis, a tropical disease primarily spread by sand flies, has been found in the mainland United States, shocking physicians who were taught that it only existed in tropical climates. The disease, which currently has no effective vaccine, has been reported in Texas, but the actual spread is difficult to track due to limited reporting. As the planet warms, diseases like leishmaniasis are spreading to new areas, posing a concern for public health. The Centers for Disease Control and Prevention is raising awareness among clinicians about the presence of leishmaniasis in the U.S. and the need for preventive measures.
