Identification and classification of high-risk areas for the presence of Aedes aegypti is not an easy task. To develop suitable methods to identify this areas is an essential task that will increase the efficiency and effectiveness of control measures and to optimize the use of resources. The objectives of this study were to identify high- risk areas for the presence of Ae. aegypti using mosquito traps and household visits to identify breeding sites; to identify and validate aspects of the remote sensing images that could characterize these areas; to evaluate the relationship between this spatial risk classification and the occurrence of Ae. aegypti; and provide a methodology to the health and control vector services and prioritize these areas for development of control measure. Information about the geographical coordinates of these traps will enable us to apply the kriging spatial analysis tool to generate maps with the predicted numbers of Ae. aegypti. Satellite images were used to identify the characteristic features the four areas, so that other areas could also be classified using only the sensing remote images. The developed methodology enables the identification of high-risk areas for Ae. aegypti and for the occurrence of Dengue, as well as Zika fever and Chikungunya fever using only sensing remote images. These results allow health and vector control services to prioritize these areas for developing surveillance and control measures. The use of the available resources can be optimized and potentially promote a decrease in the expected incidences of these diseases, particularly Dengue.
确定和分类埃及伊蚊存在的高风险区域并非易事。开发合适的方法来识别这些区域是一项必要的任务，这将提高控制措施的效率和效果，并优化资源利用。本研究的目的是使用蚊子诱捕器和入户调查来识别布雷图指数，以确定埃及伊蚊存在的高风险区域；识别和验证遥感图像中可能描述这些区域的特征；评估这种空间风险分类与埃及伊蚊发生之间的关系；并为卫生和控制媒介服务提供一种方法，为制定控制措施确定这些区域的优先级。这些诱捕器的地理坐标信息将使我们能够应用克里金空间分析工具来生成带有预测埃及伊蚊数量的地图。使用卫星图像来识别这四个区域的特征，以便仅使用遥感图像对其他区域进行分类。所开发的方法能够仅使用遥感图像识别埃及伊蚊存在的高风险区域以及登革热、寨卡热和基孔肯雅热的发生。这些结果使卫生和媒介控制服务部门能够确定这些区域的优先级，以制定监测和控制措施。可以优化现有资源的利用，并有可能降低这些疾病（特别是登革热）的预期发病率。
