Epidemiology and ecology of leishmaniasis in Latin-America

Abstract
Of the human diseases caused by protozoal parasites, leishmaniasis is probably 2nd in importance only to malaria. Chemotherapeutic drugs are toxic, expensive and not 100% effective. This, and the absence of any non-living vaccine against the disease, means that control depends on eliminating vertebrate reservoirs and/or insect vectors. Recently, a greatly increased knowledge of the Leishmania spp. involved, and of their natural hosts, helped to define the nature and extent of the problem.
