The use and land cover and its relationship with hantaviruses in the integrated development region of distrito federal and surrounding/O uso e a cobertura da terra e a sua relacao com a hantavirose na regiao integrada de desenvolvimento do distrito federal e entorno

The hantaviruses has an epidemiological many nuances with environmental changes of anthropogenic origin. So, you can see the need for understanding, regional and local level, the possible contributions that anthropogenic changes brought in relation to that disease for the Federal District and its surroundings. In this sense, the present study analyzed the categories of use and land cover in the Region Integrated Development (RIDE-DF) of the Federal District and surrounding areas, with a view to statistical evaluation of the influence of these categories in the dynamics of hantaviruses. Through the use of Geographic Information System (GIS) and statistical tests, for example, the odds ratio and the chi-square, it was possible to evaluate the spatial and temporal distribution of hantaviruses. Secondary data of cases of disease for the period 2004-2010 have identified 14 of the grievance occurrence sites in the surrounding area and 49 locations in the Federal District. It was also noted that the analysis in the Federal District, using classes--urban areas (OR = 2.9) and temporary crops (OR = 2.3)--that showed significant association measures. The results of the chi-square test indicated that the anthropogenic effects are statistically more significant in the Federal District ([chi square] = 9.5) than in its surrounding region ([chi square] = 1.8). So the anthropism is an important factor in the spread of Hantavirus in RIDE-DF. Keywords: Hantavirus; Land use; Spatial analysis; Rodent-Borne. A hantavirose possui uma epidemiologia de muitas nuances com mudancas ambientais de origem antropica. Assim, e possivel perceber a necessidade de compreensao, a nivel regional e local, das possiveis contribuicoes que as mudancas antropicas trouxeram em relacao aquela enfermidade para o Distrito Federal e seu entorno. Neste sentido, o presente estudo analisou as categorias de uso e cobertura da terra existentes na Regiao Integrada de Desenvolvimento (RIDE-DF) do Distrito Federal e Entorno, tendo em vista a avaliacao estatistica da influencia destas categorias na dinamica da hantavirose. Atraves do uso do Sistema de Informacoes Geograficas (SIG) e de testes estatisticos, como, por exemplo, o odds ratio e o qui-quadrado, foi possivel avaliar a distribuicao espaco-temporal da hantavirose. Dados secundarios de casos da doenca referentes ao periodo 2004-2010 permitiram identificar 14 locais de ocorrencia do agravo no entorno e 49 locais no Distrito Federal. Observou-se ainda nas
