A H5N6 highly pathogenic avian influenza virus (HPAIV) was detected in a black-faced spoonbill (Platalea minor) found dead in Taiwan during December 2017. Genome sequencing and phylogenetic analyses suggest the hemagglutinin gene belongs to H5 clade 2.3.4.4 Group B. All genes except neuraminidase gene shared high levels of nucleotide identity with H5N8 HPAIV identified from Europe during 2016-2017. Genetically similar H5N6 HPAIV was also identified from Japan during November 2017. Enhanced surveillance is required in this region.
在 2017 年 12 月，台湾发现一只死亡的黑脸琵鹭（Platalea minor）体内检测到 H5N6 高致病性禽流感病毒（HPAIV）。基因组测序和系统进化分析表明，血凝素基因属于 H5 分支 2.3.4.4 组 B。除神经氨酸酶基因外，所有基因与 2016-2017 年在欧洲发现的 H5N8 HPAIV 具有高度核苷酸同一性。2017 年 11 月在日本也发现了遗传上相似的 H5N6 HPAIV。该地区需要加强监测。
