Reassortant highly pathogenic avian influenza A(H5N2) clade 2.3.4.4.b viruses were detected from ducks and environmental samples in Egypt, June 2024. Genomic and phylogenetic analyses revealed a novel genotype produced by the reassortment of an A(H5N1) clade 2.3.3.4b virus with an A(H9N2) G1-like virus. Monitoring the spread of this virus is important.
2024年6月，在埃及的鸭子和环境样本中检测到重配高致病性甲型禽流感A(H5N2) 2.3.4.4.b分支病毒。基因组和系统发育分析显示，一种A(H5N1) 2.3.3.4b分支病毒与一种A(H9N2) G1样病毒重配产生了一种新型基因型。监测这种病毒的传播很重要。
