Spread by the bite of infected female sand flies, visceral leishmaniasis infects about 500,000 people annually, with the majority of cases occurring in India, Bangladesh, Nepal, Sudan and Brazil.

Every year, 2 million people become infected with one of 20 pathogenic species of Leishmania through the bites of infected female sand flies. These pick up parasites by biting an infected animal (zoonotic transmission) or an infected person (anthroponotic transmission). In their human host, Leishmania parasites reproduce inside macrophages—white blood cells that usually kill microorganisms, clear up cellular debris, and activate other immune cells. When the macrophages are full of parasites, they burst—this destruction causes the symptoms associated with leishmaniases—and the released parasites infect further macrophages.
