We characterized highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b genotype D1.1 in wild birds and a human in British Columbia, Canada, during 2024. D1.1, the predominant genotype circulating in fall 2024, is a reassortment between Eurasian A3 lineage viruses, introduced to North America in 2022, and North American lineage viruses.
2024年,我们对加拿大不列颠哥伦比亚省野生鸟类和一名人类体内的高致病性甲型禽流感(H5N1)2.3.4.4b分支基因型D1.1进行了特征描述。D1.1是2024年秋季流行的主要基因型,它是2022年引入北美的欧亚A3谱系病毒与北美谱系病毒之间的重组体。
