Maximum likelihood tree of JEV strains from the ROK using NS5/3'UTR base-sequence homologies. Phylogenetic analysis was performed using the GTR+G₄+I model of nucleotide substitution (ln(L) = -3090.1 571) and aLRT branch support (indicated at major nodes). The phylogenetic tree has been rooted at its midpoint. Scale bar represents substitutions per site.
