Sand flies are tiny tan flies — about the quarter of the size of a mosquito — that live in warm, wet, rural and forested areas. These patients all had leishmaniasis skin infections, which start with a small bump that erupts into ulcerous sores days to weeks after a sand fly bite. Like other types of insects that are finding new habitats as the climate warms, sand flies have been expanding their range in recent years. It’s not clear whether sand flies in all these states have transmitted infections to humans, however. When sand flies bite the infected rats, they can pick up the parasite and then pass it to humans.
