Although reports of human infection with influenza A(H5N6) increased in 2021, reports of similar H5N6 virus infection in poultry are few. We detected 10 avian influenza A(H5N6) clade 2.3.4.4b viruses in poultry from 4 provinces in China. The viruses showed strong immune-escape capacity and complex genetic reassortment, suggesting further transmission risk.
尽管 2021 年报告的人感染甲型流感病毒（H5N6）病例有所增加，但家禽中类似 H5N6 病毒感染的报告却很少。我们在中国 4 个省的家禽中检测到 10 株甲型流感病毒（H5N6）属 2.3.4.4b 分支病毒。这些病毒表现出较强的免疫逃逸能力和复杂的基因重配，提示存在进一步传播的风险。
