Climate variables, living conditions and the health of the population: leptospirosis in the city of Rio de Janeiro from 1996 to 2009. Ciênc. saúde coletiva [online]. 2012, vol.17, n.6, pp. 1569-1576.

Extreme climate events have major repercussions on the health of the population, especially when they cause disease or even result in victims due to accidents. The population of Rio de Janeiro is vulnerable to climate variations, mainly due to the socio-economic factors, as the city has a topography and climate that enhance this vulnerability. This article discusses the evolution of leptospirosis in the thirty-two administrative regions of the city of Rio de Janeiro from 1996 through 2009, testing the hypothesis that climate variations lead to an increase in the number of cases of the disease. The meteorological data examined were provided by the National Meteorology Institute and the Brazilian Airport Infrastructure Company. Data on the morbidity and mortality of leptospirosis was collected from Rio de Janeiro's Municipal Health and Civil Defense Department. In this work, it was concluded that there is a direct correlation between the incidence of leptospirosis and rainfall. However, in the final analysis, it must be emphasized that the oscillation of the number of cases is not only determined by rainfall, since other factors influence this dynamic, such as sanitation, in addition to environmental and social factors.
