Abstract

West Nile (WN) virus was found throughout New York State in 2000, with the epicenter in New York City and surrounding counties. We tested 3,403 dead birds and 9,954 mosquito pools for WN virus during the transmission season. Sixty-three avian species, representing 30 families and 14 orders, tested positive for WN virus. The highest proportion of dead birds that tested positive for WN virus was in American Crows in the epicenter (67% positive, n=907). Eight mosquito species, representing four genera, were positive for WN virus. The minimum infection rate per 1,000 mosquitoes (MIR) was highest for Culex pipiens in the epicenter: 3.53 for the entire season and 7.49 for the peak week of August 13. Staten Island had the highest MIR (11.42 for Cx. pipiens), which was associated with the highest proportion of dead American Crows that tested positive for WN virus (92%, n=48) and the highest number of human cases (n=10).

摘要

2000年，西尼罗河（WN）病毒在纽约州全境被发现，其中心位于纽约市及周边县。在传播季节，我们对3403只死鸟和9954个蚊虫样本进行了WN病毒检测。代表30个科和14个目的63种鸟类检测出WN病毒呈阳性。在疫情中心，检测出WN病毒呈阳性的死鸟中比例最高的是美洲乌鸦（阳性率67%，n = 907）。代表四个属的8种蚊虫检测出WN病毒呈阳性。在疫情中心，致倦库蚊每1000只蚊虫的最低感染率（MIR）最高：整个季节为3.53，8月13日的高峰周为7.49。史坦顿岛的MIR最高（致倦库蚊为11.42），这与检测出WN病毒呈阳性的死亡美洲乌鸦的最高比例（92%，n = 48）以及最高的人类病例数（n = 10）相关。
