During late summer 2016, in a northwest European region extending over Belgium, the Netherlands and the eastern border of the German state of North Rhine Westphalia, an outbreak of wild bird deaths occurred similar to those reported on the continent since 1996. Dead birds were necropsied and examined by complementary methods. Pathologic and immunohistological investigations strongly suggested an infection by Usutu virus. Subsequently, genomic segments of the said virus were detected, the virus was isolated and its complete genome was sequenced. The strain, designated Usutu-LIEGE, is a close phylogenetic relative of those isolated in Germany which form a distinct group within the USUV phylogeny, the so-called Europe_3 lineage. Should this outbreak recapitulate the characteristics of those in southwest Germany in 2011 and in/around Vienna (Austria) in 2001, it is expected that specific avian populations in the affected area will face a significant reduction in size for a few years.
2016年夏末，在一个横跨比利时、荷兰以及德国北莱茵-威斯特法伦州东部边境的西北欧地区，发生了一起野生鸟类死亡事件，与自1996年以来该大陆上所报告的情况类似。对死亡鸟类进行了尸检，并采用补充方法进行检查。病理和免疫组织学调查强烈提示为乌苏图病毒感染。随后，检测到了该病毒的基因组片段，分离出了病毒并对其完整基因组进行了测序。该毒株被命名为乌苏图-列日毒株，它在系统发育上与在德国分离出的毒株关系密切，这些毒株在美国乌苏图病毒系统发育中形成一个独特的群体，即所谓的欧洲_3谱系。如果此次疫情重现2011年德国西南部以及2001年奥地利维也纳及其周边地区疫情的特征，预计受影响地区的特定鸟类种群数量在几年内将大幅减少。
