Abstract in Portuguese
A introdução da dengue no município de São Paulo ocorreu de forma tardia em relação às demais grandes cidades do Brasil. Este estudo teve como objetivo descrever a ocorrência de dengue no município, desde a sua introdução, em 2002, até 2014, ano da primeira epidemia de maiores dimensões no território paulistano, bem como verificar possíveis associações entre a ocorrência de dengue e variáveis socioambientais. Foi realizado um estudo epidemiológico descritivo dos casos prováveis de dengue, autóctones, residentes no município, no período de 2007 a 2014. O estudo incluiu componente ecológico, de modo que se buscou verificar as possíveis associações entre a incidência de dengue nos distritos administrativos em que se divide o município e variáveis socioambientais. A incidência variou entre 2,04 em 2008, a 256,67 em 2014, no período analisado, por 100.000 habitantes. Não houve diferença na distribuição entre os gêneros. A doença foi mais frequente entre os adultos jovens. Observou-se uma distribuição espacial heterogênea entre as regiões e os distritos, com a maior incidência observada nos distritos da região Oeste da cidade, e a menor, nos distritos centrais. A proporção de casos graves foi baixa, assim como a letalidade. No período inicial, a incidência foi maior nos distritos cortados por rodovias e pelas vias marginais. Em 2014, com o aumento da incidência, essa associação desapareceu. A ocorrência de dengue no município de São Paulo apresenta características semelhantes às das primeiras décadas da ocorrência da doença no restante do país.

Abstract in English
The emergence of dengue in the municipality of São Paulo occurred late, in relation to the other large cities of Brazil. This study aimed to describe the occurrence of dengue in the municipality, since its emergence, in 2002, until 2014, year of the first large epidemic in the municipality, and verify possible associations between dengue occurrence and social and environmental variables. A descriptive epidemiologic study was carried out, using the reported autochthonous dengue probable cases among residents in the municipality, from 2007 to 2014. It was not possible to analyze the period from 2002 to 2007, because the official data system for mandatory disease reporting (SINAN) had not been used in that period. The study also included an ecologic component. It was attempted to verify possible associations between dengue incidence in the administrative districts in which the municipality is divided with social and environmental variables. The incidence varied between 2.04 per 100,000, in 2008, and 256.67 in 2014, during the studied period. No difference in the distribution according to gender was observed. The disease was more frequent among young adults. Its spatial distribution was heterogeneous among the regions and districts, with higher incidence observed in the districts of the Western region, and lower in the Central districts. The proportion of severe cases was low, as was the case-fatality rate. In the initial phase the incidence was higher in the districts crossed by highways and by the "marginal" avenues. In 2014, with increasing incidence rates, this association disappeared. The occurrence of dengue in the municipality of São Paulo presents similar characteristics to those observed during the first decades of the disease occurrence elsewhere in Brazil.
