Phylogenetic tree based on complete genome of Chinese mainland EV71.

<p>Red dots indicate the sequences from Mainland China and blue triangles indicate the sequences downloaded from GenBank. The prototype of EV71(BrCr), CVA-16(G-10) and the oldest sequences of different subgenotypes of EV71(B0-5, C1-5 subgenotypes) were included as well. Green color strain name indicate the mild case, purple color strain name indicate the severe case and pink color strain name indicate the fatal case.
