The GB virus-C and hepatitis G virus (GBV-C/HGV) are variants of the same flavivirus. This proposal attempts to clarify the conflicting nomenclature for GBV-C/HGV genotypes. The first three genotypes described were genotype 1 (West Africa); genotype 2 (US/Europe) and genotype 3 (Asia). Subsequently, two groups published data from South Africa and Southeast Asia both stating the presence of a novel '4th genotype.' These isolates are distinct phylogenetically. It is proposed that the nomenclature for genotypes 1-3 remains as per previous publications, and that the Southeast Asian isolates be known as genotype 4, and the South African isolates as genotype 5.
