Fig. 2. The estimated maximum clade credibility (MCC) phylogeny of the hemagglutination (HA) gene of H5N8 in Korea and of H5 worldwide (all variants of H5 clade 2.3.4.4). Each subgroup is marked on the right and the C0 group is labeled in red. Branch lengths represent time, and colors represent location. Red, Asia; green, Europe; blue, North America; and purple, South Korea. Numbers at the nodes show posterior probabilities >0.7.
