Emergence of a novel reassortant highly pathogenic avian influenza clade 2.3.4.4b A(H5N2) Virus, 2024

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 vi...
