Phylogenetic trees showing genetic relationships among Human Enterovirus 71 (HEV71) isolates. The neighbor-joining trees were constructed from alignment of the whole genome sequences (panel A) and nucleotide sequences of P3 (nucleotides 50677325) (panel B). The bootstrap values are shown as percentage derived from 1,000 samplings, and the scale reflects the number of nucleotide substitutions per site along the branches. Isolates from fatal cases are denoted with asterisks.
