Introdução: As mudanças climáticas podem produzir impactos sobre a saúde humana, aumentando a incidência de doenças infecciosas, principalmente as doenças transmitidas por vetores como a dengue. Este estudo analisou a relação entre a pluviosidade, temperatura e ocorrência de casos de dengue. Métodos: Estudo ecológico, realizado no município de São Luís–MA, com os casos de dengue autóctone notificados no período de 2003 a 2010, e os dados mensais de pluviosidade e temperatura. A incidências mensal de casos de dengue foi calculada por ano/100.000hab., e para a identificação da influência das variáveis climáticas e casos de dengue foi escolhido o modelo ajustado baseada no critério AIC (Akaike Information Criterion). Resultados: Foram notificados 13.444 casos de dengue entre 2003 e 2010, com picos em 2005 (309,07/100.000hab.), 2007 (358,43/100.000hab.) e 2010 (276,39/100.000hab.). A correlação dos índices pluviométricos com a ocorrência da dengue mostrou aumento de casos nos primeiros meses subsequente aos meses chuvosos. Conclusão: Houve ocorrência de casos de dengue em todos os períodos estudado, caracterizando o município como endêmico-epidêmico e o índice pluviométrico, apresentou associação positiva com o número de casos de dengue.

Abstract:
Introduction: Climate change may impact on human health by increasing incidence of infectious diseases, especially vector-borne diseases such as dengue. This study analyzed the relationship between rainfall, temperature and occurrence of dengue cases. Methods: Ecological study performed with autochthonous dengue cases reported during 2003 to 2010 in São Luís, Maranhão. Data of rainfall and temperature were collected monthly. The monthly incidence of dengue cases was calculated by year/100,000 inhabitants. In order to identify the influence of climate variables and dengue cases we used the adjusted model based on AIC (Akaike Information Criterion). Results: Thirteen thousand, four hundred forty-four cases of dengue between 2003 and 2010 were reported, with peaks in 2005 (309.07 / 100,000 inhabitants), 2007 (358.43 / 100,000 inhabitants) and 2010 (276.39 / 100,000 inhabitants). The correlation between rainfall and the occurrence of dengue cases showed increase in the first months after the rainy months. Conclusion: Occurrence of dengue cases was observed during all the period of study. Thus, this municipality is considered as an endemic and epidemic site and the rainfall index presented a positive association with the number of dengue cases.
