Few studies have investigated the many mosquito species that harbor arboviruses in Kenya. During the 2006-2007 Rift Valley fever outbreak in North Eastern Province, Kenya, exophilic mosquitoes were collected from homesteads within 2 affected areas: Gumarey (rural) and Sogan-Godud (urban). Mosquitoes (n = 920) were pooled by trap location and tested for Rift Valley fever virus and West Nile virus. The most common mosquitoes trapped belonged to the genus Culex (75%). Of 105 mosquito pools tested, 22% were positive for Rift Valley fever virus, 18% were positive for West Nile virus, and 3% were positive for both. Estimated mosquito minimum infection rates did not differ between locations. Our data demonstrate the local abundance of mosquitoes that could propagate arboviral infections in Kenya and the high prevalence of vector arbovirus positivity during a Rift Valley fever outbreak.
在肯尼亚，很少有研究调查携带虫媒病毒的多种蚊子。在 2006-2007 年肯尼亚东北部裂谷热疫情期间，从两个受影响地区（古马雷（农村）和索甘-戈杜德（城市））的住家采集了嗜人按蚊。根据诱蚊器位置将蚊子（n = 920）汇集在一起，并检测裂谷热病毒和西尼罗河病毒。捕获的最常见的蚊子属于库蚊属（75%）。在测试的 105 个蚊子池中，22%对裂谷热病毒呈阳性，18%对西尼罗河病毒呈阳性，3%对两种病毒均呈阳性。估计蚊子的最小感染率在不同地点没有差异。我们的数据表明，肯尼亚存在大量可能传播虫媒病毒感染的蚊子，并且在裂谷热疫情期间，病媒虫媒病毒阳性率很高。
