Fig 3. Phylogenetic tree containing the recombinants from the incident, higher-risk, and prevalent HIV-1 infection studies.

The phylogenetic relationships between incident recombinant strains from the community cohort (red), higher-risk cohort recombinant strains (blue), and prevalent infection recombinant strains (green) were constructed using the full-length genomes and appropriate pure subtype and recombinant reference sequences. Bootstrap values at relevant nodes are shown. The scale bar indicates a genetic distance of 10%.
