蚊子传播的感染导致一些最令人衰弱的人类疾病，包括黄热病和疟疾，但我们缺乏对疾病风险如何与人类驱动的栖息地变化相关联的理解。我们提出了一种方法来研究蚊子分布的变化和伴随的病毒感染的景观水平。在一项试点研究中，我们分析了蚊子分布沿着10公里的样带的西非雨林地区，其中包括原始林，次生林，种植园，和人类住区。不同生境类型间按蚊、伊蚊、库蚊和Uranotaenia蚊的丰度存在差异。从不同的栖息地捕获的蚊子筛选导致五个uncharacterized病毒的家庭布尼亚病毒科，冠状病毒科，黄病毒科，弹状病毒科，以及未分类的病毒的分离。聚合酶链反应筛选这五种病毒在个别蚊子的趋势表明感染特定的病毒在特定的蚊子属，不同的栖息地。基于这些初步的分析，我们认为，进一步的工作表明，调查蚊子分布和伴随虫媒病毒感染的人为景观变化的影响。
Mosquito-borne infections cause some of the most debilitating human diseases, including yellow fever and malaria, yet we lack an understanding of how disease risk scales with human-driven habitat changes. We present an approach to study variation in mosquito distribution and concomitant viral infections on the landscape level. In a pilot study we analyzed mosquito distribution along a 10-km transect of a West African rainforest area, which included primary forest, secondary forest, plantations, and human settlements. Variation was observed in the abundance of Anopheles, Aedes, Culex, and Uranotaenia mosquitoes between the different habitat types. Screening of trapped mosquitoes from the different habitats led to the isolation of five uncharacterized viruses of the families Bunyaviridae, Coronaviridae, Flaviviridae, and Rhabdoviridae, as well as an unclassified virus. Polymerase chain reaction screening for these five viruses in individual mosquitoes indicated a trend toward infection with specific viruses in specific mosquito genera that differed by habitat. Based on these initial analyses, we believe that further work is indicated to investigate the impact of anthropogenic landscape changes on mosquito distribution and accompanying arbovirus infection.
