Phylogenetic analysis of H5 clades based on HA nucleotide sequences. The HA nucleotide sequences of our H5N1 viruses (● black circle) were analyzed for clade identification against various WHO reference H5 avian influenza strains that caused human infections: H5N1 virus clades 0, 1, 2.1, 2.2, 2.3.2, and 2.3.4 and the H5N6 virus clade 2.3.4.4.
