Phylogenetic analysis of HAV sequences detected from blood donors. The phylogenetic tree was constructed using the Maximum Likelihood method using the Kimura-2 parameter + G model based on sequences of 247 bp of the VP1/2A region of the HAV genome. Samples with black diamonds were from this present study. (*) Sequence HAS-15 is a prototype of subgenotype IA, sequences HAF-203 and HM-175 are prototypes of the subgenotype IB, sequence CF-53 is a prototype of subgenotype IIB, and sequence SLF88 is a prototype of subgenotype IIA. DS49 equals PP941961, and DS62 is PP941962 in the GenBank database
