在巴西,蚊子伊蚊(Segogomyia)埃及伊蚊被认为是登革热的主要媒介,基孔肯雅,和寨卡病毒传播。最近在巴西南部进行的流行病学研究显示,登革热的发病率有所上升,引起人们对流行病控制的关注,监测,和调查。因此,这项研究旨在对Ae进行历史时空分析。过去19年巴西南部的埃及房屋指数(HI)。由于媒介侵染与气候和环境变量有关,来自巴西卫生部的HI数据,来自Giovanni基于Web的应用程序的气候数据,和来自Mapbiomas项目的环境数据被用于这项研究。我们的结果表明,在确认媒介存在的市政当局中,HI调查的数量有明显的增加,与2017年相比。环境变量,比如城市基础设施,降水,温度,和湿度,与Ae呈正相关。埃及人嗨.这是第一个分析Ae的研究。埃及伊蚊HI在巴西南部城市的调查,我们的发现有助于制定和规划疾病控制策略,以改善公共卫生。
In Brazil, the mosquito Aedes (Stegomyia) aegypti is considered the main vector of the dengue, chikungunya, and Zika arbovirus transmission. Recent epidemiological studies in southern Brazil have shown an increase in the incidence of dengue, raising concerns over epidemiological control, monitoring, and surveys. Therefore, this study aimed at performing a historical spatiotemporal analysis of the Ae. aegypti house indices (HI) in southern Brazil over the last 19 years. As vector infestation was associated with climatic and environmental variables, HI data from the Brazilian Ministry of Health, climate data from the Giovanni web-based application, and environmental data from the Mapbiomas project were used in this study. Our results showed an expressive increase in the number of HI surveys in the municipalities confirming the vector presence, as compared to those in 2017. Environmental variables, such as urban infrastructure, precipitation, temperature, and humidity, were positively correlated with the Ae. aegypti HI. This was the first study to analyze Ae. aegypti HI surveys in municipalities of southern Brazil, and our findings could help in developing and planning disease control strategies to improve public health.
