Phylogenetic trees constructed based on the <i>P1</i> (a), <i>P2</i> (b), and <i>P3</i> (c) coding regions of EV-C strains.

<p>The five EV-96 strains with available full genome sequences were included. The locations of the Guangdong strains are indicated by a black diamond. Bar, nucleotide distance as substitutions per site. Only bootstrap values of over 70% are shown.</p>
