[Contributions of epidemiology to the control of leishmaniasis].

Leishmaniasis despite government efforts, groups and individuals continues to be a major public health problem, it is estimated that globally occur between 50 000 and 90 000 new cases of visceral leishmaniasis and between 0.5 and 1 million tegumentary leishmaniasis, plus in some regions, this parasitism has an endemo-epidemic nature, and in recent years its frequency and distribution have increased. The purpose of this paper is to show some contributions of epidemiology to the control of leishmaniasis, as a result of the description and analysis of the distribution and determinants of this parasitism, extremely complex in terms of transmitter, etiological agent, reservoir and susceptible.
