Phylogeography and genomic diversity of contemporary H5 HPAIVs. (A) Maximum likelihood phylogenetic tree of H5 HA gene segments (left panel) and viral genotypes (right panel) of Vietnamese H5 HPAIVs during 2014–2017. Viruses isolated by our Hokkaido University (HU) surveillance program are indicated in corresponding horizontal gray lines (middle column panel). Supplementary Fig. S2A shows annotated tree with full strain names. Bootstrap values are shown for key nodes. The total (n) of H5 HPAIV strains per genotype is indicated in parentheses. Asterisks (*) indicate newly identified genotypes in this study. For detailed color interpretation, readers are advised to refer the online version of this article. (B) Schematic space-time genotypic transition of Vietnamese H5 HPAIVs from 2010 to 2017. Genotypes are indicated inside circles. Number (#) of H5 HPAIV strains of each genotype per year is indicated in each square. Arrows indicate the probable transition of each genotype following the existence of previous homologous HA clade assignment. Geographic origins of each virus/genotype are shape-coded as North (▲), Central (●) and South (▼) regions.
