HIV-2 subtype circulating in India (south)

J Acquir Immune Defic Syndr. 2003 Jun 1;33(2):219-22. doi: 10.1097/00126334-200306010-00017.

Abstract

The genetic types and subtypes of HIV vary from region to region. This study looked at the relative prevalence of HIV-2 subtypes in south India. Nucleotide sequencing of the HIV-2 envelope V3 region of strains from 11 individuals infected with HIV-2 and one individual who had dual infection with HIV-1 and HIV-2 was performed. Phylogenetic analysis showed that all individuals were infected with HIV-2 subtype A. These strains were from individuals who live in different regions of south India. In all, up to present, 17 strains inclusive of the authors' 12 have been sequenced, and subtype A of HIV-2 is seen in both monoinfections and dual infections with HIV-1 in India.
