New Insights into the Origin of the HIV Type 1 Subtype A Epidemic in Former Soviet Union's Countries Derived from Sequence Analyses of Preepidemically Transmitted Viruses

Abstract excerpt

The HIV-1 subtype A epidemic affecting injecting drug users (IDU) in former Soviet Union (FSU) countries started dramatically in Odessa, southern Ukraine, in 1995, and is caused by a variant of monophyletic origin, often designated IDU-A. We phylogenetically analyzed one near full-length genome and two partial sequences of three HIV-1 subtype A viruses collected in St. Petersburg, Russia, heterosexually...
