Genetic analysis of HIV-1 strains in rural eastern Cameroon indicates the evolution of second-generation recombinants to circulating recombinant forms.

The HIV-1 genetic diversity in most parts of Cameroon is well described and shown to be very broad. However, little is known about the composition of the HIV-1 epidemic in the rural parts of eastern Cameroon. Therefore, we investigated 25 specimens from this region for their subtypes in gag, pol, and env gene fragments.
