Additions and changes from assignments proposed in ² shown in bold.

^*Consensus proposed genotype/subtype names. Where multiple sequences of a HCV genotype are available, two sequences have been listed, prioritized by (a) publication date or (b) submission date when unpublished.

^†Locus (or isolate name if locus is the same as the accession number).

^‡Previously described as 4b.^7,14

^§Sequence obtained from acute phase plasma of a chimpanzee experimentally infected with (human-derived) isolate SA13.
