Phylogenetic analysis of all HAV isolates obtained from 2019 to 2020 in sentinel provinces. Nucleotide (nt) sequences from the VP1/2A junction region (391 bases) of reference strains retrieved from GenBank (*) and 118 sequences from this study were analyzed by the neighbor-joining (NJ) method. Branches with colors indicate different clusters. The numbers at the nodes indicate bootstrap percentages over 1,000 replicates (only values >70% are shown). The bar length indicates genetic distance. HAV, hepatitis A virus.
