As part of West Nile (WN) virus surveillance in New York State in 2000, 71,332 ill or dead birds were reported; 17,571 (24.6%) of these were American Crows. Of 3,976 dead birds tested, 1,263 (31.8%) were positive for WN virus. Viral activity was first confirmed in 60 of the state's 62 counties with WN virus-positive dead birds. Pathologic findings compatible with WN virus were seen in 1,576 birds (39.6% of those tested), of which 832 (52.8%) were positive for WN virus. Dead crow reports preceded confirmation of viral activity by several months, and WN virus-positive birds were found >3 months before the onset of human cases. Dead bird surveillance appears to be valuable for early detection of WN virus and for guiding public education and mosquito control efforts.
作为2000年纽约州西尼罗河(WN)病毒监测的一部分,报告了71332只生病或死亡的鸟类;其中17571只(24.6%)是美洲乌鸦。在检测的3976只死鸟中,1263只(31.8%)WN病毒呈阳性。该州62个县中有60个县首次确认了病毒活动,这些县有WN病毒阳性的死鸟。在1576只鸟(占检测鸟的39.6%)中发现了与WN病毒相符的病理结果,其中832只(52.8%)WN病毒呈阳性。死乌鸦报告比病毒活动确认早几个月,WN病毒阳性鸟类在人类病例出现前3个月以上就被发现。死鸟监测对于早期发现WN病毒以及指导公众教育和蚊虫控制工作似乎很有价值。
