Sequence similarity of epitopes among common strains was performed. A VP1 and B VP2 epitope sequence conservation was analyzed in different genotypes of norovirus. Representative strains, mutant strains and recombinant strains of genotypes GII.4, GII.3, and GII.2 were selected for comparison. Each letter represents an amino acid residue, and the size of the letter reflects the conservation of this site
