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.
目前,避免新的登革热疫情的最佳方法是控制蚊媒埃及伊蚊。因此,本研究旨在确定和分析巴西塞尔希培州阿拉卡茹市埃及伊蚊“关键场所”的空间分布。在登革热疫情之前、期间和之后以及在不同降水条件下(雨季结束、雨季开始和旱季)进行了三次昆虫学调查。通过不止一次调查呈阳性以及存在蛹来确定关键场所。蚊子的空间分布和扩散采用点模式分析,使用核密度估计器和缓冲区密度估计器。关键场所负责维持该地区的感染情况,不受环境条件和疫情时期的影响,作为产生蚊子的疫源地,这些蚊子可传播到邻近社区的区域。因此,为了更有效,病媒控制措施应针对这些场所。
