Molecular Epidemiology of HIV-1 Subtype G in the Russian Federation.

Although HIV-1 subtype A has predominated in Russia since the end of the 20th century, other viral variants also circulate in this country. The dramatic outbreak of HIV-1 subtype G in 1988-1990 represents the origin of this variant spreading in Russia. However, full genome sequencing of the nosocomial viral variant and an analysis of the current circulating variants have not been conducted.
