Abstract

Brazil has experienced a progressive and alarming increase of dengue cases in recent years. Studying the spatial and temporal distribution of dengue cases and larvae infestation in urbanized areas is relevant to recognition patterns of cases and location of the higher incidence of vectors, directing epidemiological surveillance actions. The confirmed cases of autochthonous and imported dengue and the infestation rate in the period from 2005 to 2014 in the city of Itu (São Paulo) were investigated. The work was performed using geoprocessing tools to calculate the incidence by neighborhood, obtaining the relative risk map and the determination of the spatial autocorrelation between cases of dengue through the Local and Global Moran Indices. The year 2013 presented the highest notification and registry of autochthonous and imported cases of dengue, being the highest rates were founded at the central and northwest part with significant occurrences. In the districts dengue ranged from 0 to 119 cases, with the highest concentration in the central region. The average incidence of dengue fever is high in the central and northwestern part, with a maximum value of 11.9 per 100.000 inhabitants. In addition, there was a spatial autocorrelation between central and peripheral areas, while the relative risk of the disease has a higher prevalence in the central part, but does not induce the absence of risk occurrences in other areas.
