title: [Identification and spatial distribution of key premises for Aedes aegypti in the Porto Dantas neighborhood, Aracaju, Sergipe State, Brazil, 2007-2008].
abstract: Currently the best way to avoid new dengue epidemics is to control the mosquito vector Aedes aegypti. This study thus aimed to identify and analyze the spatial distribution of "key premises" for Ae. aegypti in Aracaju, Sergipe State, Brazil. Three entomological surveys were performed prior to, during, and after the dengue epidemic and in different conditions of precipitation: the end of the rainy season, beginning of the rainy season, and the dry season. Key premises were identified by positivity in more than one survey and presence of pupae. Spatial distribution and dispersal of mosquitoes used analysis of point patterns, with the kernel and buffer density estimator. Key premises were responsible for maintaining infestation of the area, independently of environmental conditions and the period in the epidemic, serving as foci generating mosquitoes that can spread to areas adjacent to the neighborhood. Thus, in order to be more effective, vector control measures should target these properties.
