Abstract
INTRODUCTION: Visceral leishmaniasis (VL) is an important parasitic disease. We evaluated the epidemiological aspects and spatial distribution of visceral leishmaniasis in Governador Valadares, Brazil.METHODS: All cases of VL, registered by the municipal health department, were analyzed and georeferenced.RESULTS: The human mortality rate was 15% and canine seroprevalence rate was 29.0%. Higher numbers of canine VL cases correlated with higher incidence of human cases.CONCLUSIONS: The high rate of canine seroprevalence, resurgence of the human disease, and correlation between canine and human VL reinforces the role of the dog in disease transmission within the municipality.

Summary
Visceral leishmaniasis (VL) is an important parasitic disease. We evaluated the epidemiological aspects and spatial distribution of visceral leishmaniasis in Governador Valadares, Brazil. In 2008, the disease re-emerged in Governador Valadares, considered an endemic area due to the active transmission of VL7. Spatial analysis would enable studying the superposition of human and canine VL cases, and this may aid the planning of disease control measures.
