Open-access Association of environmental variables with the leptospirosis occurrence in dogs and humans at São Paulo city

A spatial analysis of the human and canine leptospirosis occurrence was performed in São Paulo city in 2007, associated with environmental risk variables such as flooding and rodent control sites. Clusters of flooding sites were found in 12 census sectors, and human leptospirosis in 4 census sectors, without correlation between them. Clusters of canine cases were not found, possibly due to lack of notification. The proportions of human cases in and out of rodent control areas were, respectively, 7:199,600 and 9:257,980. Rodent control measures minimized the effects of the risk factors in the leptospirosis transmission to humans.
