Visceral leishmaniasis. View of a starving young boy suffering from visceral leishmaniasis (kala- azar). He has the extreme muscle wastage associated with this condition. This tropical disease is caused by Leishmania sp., a parasitic protozoan. Leishmaniasis is transmitted by bites from infected sand-flies. This is the more serious form which causes fever and, without treatment, can result in death. Drug treatment is very effective. Photographed in Sudan.
