A dengue e uma virose aguda, causada por quatro diferentes sorotipos de virus (D-1, D-2, D-3 e D-4) e e considerada uma doenca endemica no Brasil. Os primeiros casos confirmados de dengue no Distrito Federal foram registrados em 1991 e ate hoje diversas regioes administrativas apresentam quantidades expressivas de casos, principalmente Planaltina. O presente trabalho buscou analisar a distribuicao espacial da dengue na Regiao Administrativa de Planaltina, para o ano de 2014, focando na existencia de correlacao entre casos de dengue e fatores socioambientais. A metodologia consistiu em i) levantamento de dados, com destaque para dados socioambientais e casos de dengue, bem como a sua espacializacao; e ii) processamento e analise dos dados. O ano de 2014 foi um ano epidemico no Distrito Federal, o que se refletiu em Planaltina, a qual atingiu uma taxa de incidencia de 1.078,97 casos por 100 mil habitantes. A espacializacao da taxa de incidencia por setor censitario mostrou-se alta em boa parte dos setores urbanos, mas tambem se fez presente em alguns setores rurais. A correlacao de Pearson mostrou-se positiva para a variavel pessoa responsavel com rendimento nominal mensal de ate 3 salarios minimos (PRR3) e negativa para as variaveis domicilio particular permanente sem coleta de lixo (DSCL) e domicilio particular permanente sem abastecimento de agua (DSAA). O Indice de Moran foi de 0,418, indicando uma correlacao espacial positiva. Os resultados demonstram que, para compreender a complexa dinâmica da dengue, e necessario utilizar diferentes tecnicas e variaveis socioambientais, alem da propria dimensao espacial.Palavras–chave: Geoprocessamento, Aedes, Geografia da saude, Taxa de incidencia, Indice de Moran.AbstractDengue is an acute virus caused by four different virus serotypes (D-1, D-2, D-3 and D-4) and is considered an endemic disease in Brazil. The first confirmed cases of dengue in the Federal District were recorded in 1991, and until today several administrative regions have significant amounts of cases, mainly Planaltina. The present work aimed to analyse the spatial distribution of dengue in the Administrative Region of Planaltina, for the year 2014, focusing on the existence of a correlation between dengue cases and socio-environmental factors. The methodology consisted of i) data collection, with emphasis on socio-environmental data and cases of dengue, as well as its spatialization; and ii) data processing and analysis. The year 2014 was an epidemic year in the Federal District, which was reflected in Planaltina, which reached an incidence rate of 1,078.97 cases per 100 thousand inhabitants. The specialisation of the incidence rate by census tract has been high in many urban sectors, but it has also been present in some rural sectors. Pearson's correlation was positive for the variables responsible person with monthly nominal income of up to 3 minimum wages (PRR3) and negative for the variables permanent private household without garbage collection (DSCL) and permanent private household without water supply (DSAA). The Moran Index was 0.418, indicating a positive spatial correlation. The results demonstrate that, in order to understand the complex dynamics of dengue, it is necessary to use different socio-environmental techniques and variables, besides the spatial dimension itself.Keywords: Geoprocessing; Aedes; Geography of health; Moran's Index; Incidence rate.
