[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. Based on the review of the scientific literature in the context of a descriptive, documentary and retrospective study, the objective of this paper was achieved. It is concluded that the usefulness of epidemiology in the control of leishmaniasis is clear or in any case reaffirms the validity and practicality of epidemiology in the programmatic and operational task of health intervention in the case of leishmaniasis.
