West Nile virus (WNV) is a mosquito-transmitted flavivirus with wild birds as its natural hosts. Ravens, falcons and jays are highly susceptible for WNV and develop deadly encephalitis, while other bird species undergo only subclinical infections. Migratory birds are efficient vectors for geographic spreading of WNV. Until now, WNV infections have not been diagnosed in Germany, but infections in humans and horses have occurred recently in Austria, Hungary and Italy. To investigate potential WNV introduction by infected wild birds, we have monitored the serological status of ducks in three national sentinel stations. No WNV-positive reactions were found, whereas sera from coots from northern Iran were positive.
西尼罗河病毒（WNV）是一种通过蚊子传播的黄病毒，野生鸟类是其自然宿主。乌鸦、猎鹰和松鸦极易感染 WNV，并发展为致命性脑炎，而其他鸟类仅发生亚临床感染。候鸟是 WNV 地理传播的有效媒介。到目前为止，WNV 感染尚未在德国确诊，但奥地利、匈牙利和意大利最近报告了人类和马匹感染病例。为了调查受感染野生鸟类引入 WNV 的可能性，我们在三个国家监测站监测了鸭子的血清学状况。未发现 WNV 阳性反应，而来自伊朗北部的黑水鸡血清呈阳性。
