Leishmaniasis is a parasitic disease caused by Leishmania parasites transmitted through the bites of infected sand flies. There are three main forms of leishmaniasis: cutaneous, visceral, and mucocutaneous. Cutaneous leishmaniasis causes skin ulcers, visceral leishmaniasis affects internal organs like the spleen and liver, and mucocutaneous leishmaniasis can destroy mucous membranes in the nose, mouth, and throat. Risk factors include living in or traveling to tropical and subtropical regions where the disease is common, as well as poverty, malnutrition, and immunosuppression. Symptoms vary depending on the type of leishmaniasis. Treatment
