我们检测了2008至2009年间从墨西哥梅里达的学校采集的埃及伊蚊的数量和登革病毒(DENV)的存在。来自24所学校的背包抽吸产生了468名女性Ae。埃及伊蚊和1,676只雌性致倦库蚊。天哪。埃及伊蚊女性最常从教室收集，其次是办公室和卫生间。在这些雌性动物中，24.7%是新鲜喂养的。对118个Ae池进行了检查。检出DENV RNA的埃及伊蚊雌虫(共415只)产生19个阳性池(16.1%)。从24所学校的11所学校(45.8%)检测到DENV感染池，这些池来自不同的房间类型，包括教室、办公室和卫生间。每100Ae中DENV总感染率。埃及伊蚊女性为4.8人。我们的结论是，梅里达的学校为学生、教师和其他人员暴露在蚊子和感染登革热病毒的Ae的叮咬中提供了危险环境。埃及伊蚊雌性。
We determined abundance of Aedes aegypti mosquitoes and presence of dengue virus (DENV) in females collected from schools in Merida, Mexico, during 2008 and 2009. Backpack aspiration from 24 schools produced 468 females of Ae. aegypti and 1,676 females of another human biter, Culex quinquefasciatus. Ae. aegypti females were collected most commonly from classrooms followed by offices and bathrooms. Of these females, 24.7% were freshly fed. Examination of 118 pools of Ae. aegypti females (total of 415 females) for presence of DENV RNA produced 19 positive pools (16.1%). DENV-infected pools were detected from 11 (45.8%) of 24 schools and came from different room types, including classrooms, offices, and bathrooms. The overall rate of DENV infection per 100 Ae. aegypti females was 4.8. We conclude that schools in Merida present a risk environment for students, teachers, and other personnel to be exposed to mosquitoes and bites of DENV-infected Ae. aegypti females.
