Abstract
Two novel reassortant highly pathogenic avian influenza viruses (H5N1) clade 2.3.4.4b.2 were identified in dead migratory birds in China in November 2021. The viruses probably evolved among wild birds through different flyways connecting Europe and Asia. Their low antigenic reaction to vaccine antiserum indicates high risks to poultry and to public health.
摘要
2021 年 11 月，在中国死亡的候鸟中发现了两株新型重配高致病性禽流感病毒（H5N1），属 2.3.4.4b.2 分支。这些病毒可能是通过连接欧洲和亚洲的不同迁徙路线在野鸟中进化而来。它们对疫苗抗血清的低抗原反应表明对家禽和公共卫生存在高风险。
