Figure 5. The bootscanning plots of 26 near-full-length sequences and 6 half-genome sequences of HIV-1 strains isolated from Dehong IDUs with diagnosis year in chronological order.

In the recombination analyses, a subtype C strain from India (95IN21068) (pink) and a subtype B′ strain from Yunnan (RL42) (blue) was used as subtype references, and a CRF01_AE strain from Thailand (CM240) (green) was used as an out-group control.
