B55: Leishmaniasis

Leishmaniasis is a group of diseases caused by single-celled parasites called Leishmania. The parasites are transmitted by the bite of sand flies who are infected with these parasites. The effects of this disease may differ widely, ranging from skin sores to affecting vital internal organs. Cutaneous Leishmaniasis, the most common form, results in skin sores, while visceral Leishmaniasis affects internal organs like the spleen, liver, and bone marrow, often causing fever, weight loss, swelling of the spleen and liver, and anemia. The course of the disease can vary greatly and will depend on the form of Leishmaniasis you have. If left untreated, some forms of the disease can be fatal. It's primarily seen in parts of Asia, Africa, South and Central America, and Southern Europe.
