Maximum clade credibility FMDV O/ME-SA/PanAsia viruses collected in Vietnam (and additional 3 sequences from China and Kazakhstan) between 2010 and 2014. Nodes and branches of the trees are colored according to the location with the higher posterior probability in the reconstructed phylogeny. Ancestors of the two divergent clusters are inferred to exist in the Northeast. Clades A and B represent the two main O/ME-SA/PanAsia sublineages that have diverged recently in Vietnam. Characteristics of the sampled viruses (clinical stage: C., host species: H., and location: L.) are indicated in colored columns aligned to the right of the tree, color coding is indicated in the metadata legend.
