Fig 2. Phylogenetic comparison of pure HIV-1 subtype sequences retrieved from prevalent and incident infections.

Fig 2

Full genome sequences from prevalent HIV-1 subtype A1, C, D and G strains previously identified in 1999–2000 (green), a higher-risk (MSM and FSW) cohort identified in 2006 (blue), and the community cohort incident infections identified during this study in 2003–2006 (red), including relevant reference sequences (black) were used to construct a neighbor-joining tree. Bootstrap values at relevant nodes are shown. The scale bar indicates a genetic distance of 10%. Incident infection study participants 05KE851891V4 and 06KE795643V7 (*) are likely linked: pairwise genetic distance of 0.4% (SE 0.06%).
