Leishmaniasis is a parasitic disease spread by the bite of infected sand flies. There are several different forms of leishmaniasis. The most common are cutaneous and visceral. The cutaneous type causes skin sores. The visceral type affects internal organs such as the spleen, liver and bone marrow. People with this form usually have fever, weight loss, and an enlarged spleen and liver. Visceral disease can be deadly without proper treatment. Leishmaniasis is found in parts of the Middle East, Central America, South American, Asia, Africa, and southern Europe. Most of these countries are in the tropics and subtropics. It is possible but very unlikely to get this disease in the United States.
