Abstract

The divergence of the A(H5) hemagglutinin (HA) gene of highly pathogenic avian influenza (HPAI) viruses (A/goose/Guangdong/96 lineage) was analyzed by phylogenetic and average pairwise distance methods to identify new clades that merit nomenclature changes. Three new clade designations were recommended based on division of clade 2.1.3.2a (Indonesia), 2.2.1 (Egypt) and 2.3.4 (widespread detection in Asia, Europe and North America) that includes newly emergent HPAI virus subtypes H5N2, H5N3, H5N5, H5N6 and H5N8.
