Análise espacial dos casos de leishmaniose visceral canina no município de Itaqui (2009-2016)

Abstract

Leishmaniasis is an emerging disease in developing countries. With characteristics of rural zoonosis, it has been frequently described in urban centers and affects dogs and humans. The objective of this study was to analyze records of the Veterinary Field Protocol used by Sanitary Surveillance in the municipality of Itaqui, state of Rio Grande do Sul, between 2009 and 2016. A total of 1.392 records were analyzed, 54,74% of dogs negative for LVC and 44,54% of dogs tested positive for LVC. The most important neighborhoods were: Centro (209), Chácara (56), Cidade Alta (50), Capelinha (40) and Ponte Seca (39). With the use of Geographic Information System (GIS) tools, it was possible to detect areas with higher occurrence of cases. In the Centro and Ponte Seca districts, it was identified as the first infection site in dogs, relating to these cases riverine zones and vegetation densities, risk factors for vector proliferation. Studies in the area of epidemiology illustrate the prevalence of the disease in population groups comparing or differentiating in defined risk areas.
