Picture of Leishmaniasis
Leishmaniasis is caused by a parasite that spreads to humans through the bite of infected Phlebotomus sand flies and found in the tropical countries of Central and South America, the Middle East, East Africa, and East Asia. It causes nodules or sores to form on the skin, including the skin of the face. Affected people may have a single lesion or many lesions. Sores heal slowly over months to years and leave scars.
