A West Nile virus (WNV) surveillance system was created and implemented in New York State (NYS) in 2000 and described previously (White et al. 2001). We examine and evaluate the results of mosquito and virus surveillance for 2000 through 2004 exclusive of New York City. Forty-nine counties submitted 1,095,426 mosquitoes in 35,280 pools for WNV assay. Specimens of 47 species were tested, with Culex species accounting for 47.6% of all pools tested. WNV was detected in 814 pools from 10 species, with combined Culex pipiens/Culex restuans pools accounting for 90.8% of all detections. Pools submitted from gravid traps were 5.7 times more likely to be positive than submissions from carbon dioxide-baited light traps. Most human WNV cases resided in counties that conducted mosquito surveillance. Local health departments' use of mosquito surveillance information often led to an enhanced disease prevention response. In NYS, Cx. pipiens/Cx. restuans groups are most likely vectors of WNV. Future efforts to improve system efficacy are discussed.
2000年，纽约州创建并实施了西尼罗河病毒（WNV）监测系统，此前已有相关描述（怀特等人，2001年）。我们对2000年至2004年纽约市以外地区的蚊虫和病毒监测结果进行了检查和评估。49个县提交了35280组共1095426只蚊子用于WNV检测。对47个物种的样本进行了检测，其中库蚊属物种占所有检测样本的47.6%。在来自10个物种的814组样本中检测到了WNV，其中致倦库蚊/环跗库蚊混合样本占所有检测阳性样本的90.8%。来自孕蚊诱捕器的样本检测呈阳性几率比二氧化碳诱蚊灯诱捕器的样本高5.7倍。大多数人类WNV病例所在的县都开展了蚊虫监测。当地卫生部门对蚊虫监测信息的利用常常促使疾病预防反应得到加强。在纽约州，致倦库蚊/环跗库蚊种群最有可能是WNV的传播媒介。文中还讨论了未来提高系统效能的努力方向。
