We present the first documented case of highly pathogenic avian influenza virus (HPAIV) subtype H5N5 in an Atlantic walrus (). The animal was found dead in Svalbard, Norway, in 2023. Sequence analysis revealed the highest genetic similarity with virus isolates from different avian hosts.
我们报告了在一头大西洋海象身上首次记录到的高致病性禽流感病毒（HPAIV）H5N5亚型感染病例。这头海象于2023年在挪威斯瓦尔巴群岛被发现死亡。序列分析显示，其与来自不同禽类宿主的病毒分离株具有最高的基因相似性。
