We report the complete genome sequence of a highly divergent strain of human immunodeficiency virus type 2 (HIV-2), 96FR12034, identified in France from a patient of West African origin. This lineage, H, represents only the third definitive instance of a monkey-to-human transfer of SIVsm that has given rise to pathogenic HIV-2. As the different "subtypes" of HIV-2 are analogous to the different groups of HIV-1 we propose that HIV-2 subtypes henceforth by renamed groups in agreement with the HIV Nomenclature Committee. The single-strain lineages C to G and the 96FR12034 lineage identified here should be considered only as putative groups until related strains are identified that confirm circulation of these viruses in the human population.
