The Bayesian maximum clade credibility (MCC) host discrete traits tree for 348 bp HEV ORF2 nucleotide sequences (nt position 6022–6369) of 19 Vietnamese strains, and reference strains obtained from the GenBank database. The phylogenetic host tree indicated the transmission between HEV hosts, the host at node indicated the ancestor of sub-group and the number at the node indicated the posterior probability. The bar at the bottom of the figure denotes evolutionary distance
