Leishmaniasis Leishmaniasis is present throughout the rain forests of southeastern Peru. It is a skin lesion caused by a protozoan transmitted by a certain kind of small biting fly. There is no vaccination against it but it is curable in every case. The selected cure, injections of pentavalent antimony (Glucantime), is uncomfortable. Leishmaniasis is also very easy to prevent by wearing long-sleeved shirts, pants, and repellent on exposed skin at all times, and sleeping under mosquito nets.
