The Camargue area of southern France experienced the re-emergence of West Nile Virus (WNV) in the late summer of 2000 and 2004. Immediately preceding the 2004 outbreak, samples were collected from 432 birds of 32 different species captured in mist nets and from 201 Cattle Egret (Bubulcus ibis) nestlings sampled in their nests between 1 April and 12 June 2004. West Nile virus neutralizing titers of >/=40 were detected in 4.8% (95% confidence limit, 2.9-7.5%) of the adult birds and in 1.6% (0.3-4.6%) of the egret nestlings. Migratory passerines had a higher prevalence of WNV neutralizing antibodies (7.0%) than did resident and short-distance migratory passerines (0.8%), suggesting exposure to WNV or a related flavivirus during overwintering in Africa.
法国南部的卡马尔格地区在2000年夏末和2004年再次出现西尼罗河病毒（WNV）。在2004年疫情爆发前夕，于2004年4月1日至6月12日期间，从用雾网捕获的32种不同鸟类的432只鸟以及从巢中采集的201只牛背鹭（Bubulcus ibis）雏鸟身上采集了样本。在4.8%（95%置信限，2.9 - 7.5%）的成年鸟类和1.6%（0.3 - 4.6%）的牛背鹭雏鸟中检测到西尼罗河病毒中和滴度≥40。候鸟雀形目鸟类的WNV中和抗体流行率（7.0%）高于留鸟和短距离迁徙雀形目鸟类（0.8%），这表明在非洲越冬期间接触了WNV或相关黄病毒。
