登革热和其他媒介传播的疾病在哥伦比亚具有重要的公共卫生意义。病媒监测和控制活动往往集中在家庭一级。人们对包括学校在内的非家庭场所在维持媒介传播疾病传播方面的重要性知之甚少。这份文件的目的是确定哥伦比亚两个城市农村学校的蚊子种类组成，并评估学校环境中媒介传播疾病的潜在风险。2011年旱季和雨季在农村学校进行了昆虫学调查。共发现12种蚊虫：埃及伊蚊、假按蚊、冠状库蚊、CX。Ququiefasciatus和Limatus duhamii幼虫和成虫，Ae.River atilis、CX.Nigripalpus、CX.Corniger和Psorophora ferox仅为幼态；仅成体的角叉尾轮虫、马血藻和斑点毛滴虫。最常见的蚊子种类是CX。[医]五倍子属教室里有最多的成年雌性Ae。埃及伊蚊和Cx.[医]五倍子属最常见的Ae.埃及伊蚊的滋生点是被归类为“其他”的容器(如罐头)，其次是用于储水的容器。埃及伊蚊在雨季有很高的感染率。我们的结果表明，农村学校可能是登革热和其他蚊媒传播疾病的重要传播中心。我们建议在农村学校实施公共卫生计划，以预防媒介传播疾病。
Dengue and other vector-borne diseases are of great public health importance in Colombia. Vector surveillance and control activities are often focused at the household level. Little is known about the importance of nonhousehold sites, including schools, in maintaining vector-borne disease transmission. The objectives of this paper were to determine the mosquito species composition in rural schools in 2 municipalities in Colombia and to assess the potential risk of vector-borne disease transmission in school settings. Entomological surveys were carried out in rural schools during the dry and rainy seasons of 2011. A total of 12 mosquito species were found: Aedes aegypti, Anopheles pseudopunctipennis, Culex coronator, Cx. quinquefasciatus, and Limatus durhamii in both immature and adult forms; Ae. fluviatilis, Cx. nigripalpus, Cx. corniger, and Psorophora ferox in immature forms only; and Ae. angustivittatus, Haemagogus equinus, and Trichoprosopon lampropus in adult forms only. The most common mosquito species was Cx. quinquefasciatus. Classrooms contained the greatest abundance of adult female Ae. aegypti and Cx. quinquefasciatus. The most common Ae. aegypti breeding sites were containers classified as "others'' (e.g., cans), followed by containers used for water storage. A high level of Ae. aegypti infestation was found during the wet season. Our results suggest that rural schools are potentially important foci for the transmission of dengue and other mosquito-borne diseases. We propose that public health programs should be implemented in rural schools to prevent vector-borne diseases.
