Leishmaniasis is a tropical/sub-tropical disease, spread by the bite of infected sandflies. There are several different forms of leishmaniasis in people: cutaneous leishmaniasis causes skin sores, visceral leishmaniasis causes systemic disease. Without treatment, most patients with the visceral disease will die and those with diffuse cutaneous and mucocutaneous disease can suffer long infections associated with secondary life-threatening infections.
