Hurricane Katrina caused massive destruction and flooding along the Gulf Coast in August 2005. We collected mosquitoes and tested them for arboviral infection in a severely hurricane-damaged community to determine species composition and to assess the risk of a mosquito-borne epidemic disease in that community about 6 wk after the landfall of Hurricane Katrina. Light-trap collections yielded 8,215 mosquitoes representing 19 species, while limited gravid-trap collections were not productive. The most abundant mosquito species was Culex nigripalpus, which constituted 73.6% of all specimens. No arboviruses were detected in any of the mosquitoes collected in this survey, which did not support the assertion that human risk for arboviral infection was increased in the coastal community 6 wk after the hurricane.
2005年8月，卡特里娜飓风给墨西哥湾沿岸地区带来了大规模破坏和洪水。我们在一个遭受飓风严重破坏的社区收集蚊子，并检测它们是否感染虫媒病毒，以确定物种组成，并评估在卡特里娜飓风登陆约6周后，该社区发生蚊媒传染病的风险。灯光诱捕收集到8215只蚊子，分属19个物种，而有限的孕蚊诱捕则没有收获。最常见的蚊子种类是致倦库蚊，占所有标本的73.6%。在本次调查收集的任何蚊子中均未检测到虫媒病毒，这并不支持飓风过后6周沿海社区人群感染虫媒病毒的风险增加这一说法。
