Phylogenetic dendrogram were drawn on the basis of the 891-nt sequence of entire VP1 gene using the Neighbor-Joining method of MEGA software (version 4.0) for 14 selected Fuyang representative isolates and other HEV71 strains of known subgenotypes listed in Table 1. The bootstrap values from 1000 pseudoreplicates for major lineages within the tree are shown as percentages. The prototype CVA16 strain (G-10) was used as outgroup. Solid diamond indicated the fatal cases; Solid triangle indicated the severe cases; Solid round indicated the outpatients; Triangle indicated the HEV71 sequences from other provinces in China between 1997-2008 available in GenBank database.
