After an outbreak of West Nile virus (WNV) infections in people, horses, and wildlife in Staten Island, NY, during the summer of 2000, we surveyed the bird population of the island for evidence of infection. Neutralizing antibodies were detected in 59 of 257 (23.0%) resident birds and none of 96 transient (migrating) birds sampled in early October. Species with the greatest seroprevalence were northern cardinal (Cardinalis cardinalis) (69.2%) and rock dove (Columba livia) (54.5%). House sparrows (Passer domesticus) and chickens (Gallus gallus) had lower than expected seroprevalences, 8.6% and 5.5%, respectively. The geographic distribution of seropositivity suggested focal transmission at several locations on the island. The concentration of seropositive birds among resident bird populations on Staten Island supports the concept that many birds survive WNV infection and that some of these play an important role in the WNV-bird-mosquito transmission cycle.
2000年夏季，纽约市斯塔滕岛出现了西尼罗河病毒（WNV）在人类、马匹和野生动物中感染的疫情，之后我们对该岛的鸟类种群进行了调查，以寻找感染证据。在257只留鸟中有59只（23.0%）检测到中和抗体，而10月初采样的96只候鸟均未检测到。血清阳性率最高的物种是北美主红雀（Cardinalis cardinalis）（69.2%）和原鸽（Columba livia）（54.5%）。家麻雀（Passer domesticus）和鸡（Gallus gallus）的血清阳性率低于预期，分别为8.6%和5.5%。血清阳性的地理分布表明该岛多个地点存在局部传播。斯塔滕岛留鸟种群中血清阳性鸟类的集中情况支持了这样一种观点，即许多鸟类在WNV感染中存活下来，其中一些在WNV-鸟类-蚊子传播循环中发挥着重要作用。
