To determine circulation of West Nile virus (WNV) during nonepidemic times, we serosurveyed wild birds of Morocco in 2008. We found antibodies against WNV in 12 (3.5%) birds, against Usutu virus in 1 (0.3%), and against both in 2 (0.6%). High WNV prevalence among juvenile birds suggests local virus circulation among resident birds.
为了在非流行期间确定西尼罗河病毒(WNV)的传播情况,我们在 2008 年对摩洛哥的野生鸟类进行了血清学调查。我们在 12 只(3.5%)鸟类中发现了针对 WNV 的抗体,在 1 只(0.3%)鸟类中发现了针对乌舒图病毒的抗体,在 2 只(0.6%)鸟类中发现了针对两种病毒的抗体。幼鸟中高的 WNV 流行率表明当地居留鸟类中存在病毒循环。
