Phylogenetic analysis of HA proteins in H5N1 VN, RG6, and selected circulating H5N2 viruses (2013–2017) in Taiwan Maximum likelihood phylogenies of HA genes from H5Nx viruses in this study, including A/VietNam/1203/2004 H5N1 Human CDC RG (in blue), A/AnHui/1/2005 H5N1 Human IBCDC-RG6 (in purple), KP714479 A/goose/Taiwan/01004/2015 4 H5N2 goose VLP (in red) are depicted. This analysis encompasses 164 circulating H5N2 strains to illustrate the phylogenetic relationship of H5N2 viruses in Taiwan before and after the 2015 large outbreak. Bootstrap support and Bayesian posterior clade classifications are indicated in the phylogenetic tree.
