Phylogenetic network analysis and understanding of waterfowl migration patterns suggest that the Eurasian H5N8 clade 2.3.4.4 avian influenza virus emerged in late 2013 in China, spread in early 2014 to South Korea and Japan, and reached Siberia and Beringia by summer 2014 via migratory birds. Three genetically distinct subgroups emerged and subsequently spread along different flyways during fall 2014 into Europe, North America, and East Asia, respectively. All three subgroups reappeared in Japan, a wintering site for waterfowl from Eurasia and parts of North America.
系统发育网络分析以及对水鸟迁徙模式的理解表明，欧亚H5N8 2.3.4.4分支禽流感病毒于2013年末在中国出现，2014年初传播至韩国和日本，并在2014年夏季通过候鸟抵达西伯利亚和白令地区。2014年秋季出现了三个基因不同的亚群，随后分别沿着不同的迁徙路线传播到欧洲、北美和东亚。所有这三个亚群都在日本再次出现，日本是来自欧亚大陆和北美部分地区水鸟的越冬地。
