(A) Bootscanning analysis was conducted using a window size of 300 bp and a step size of 20 bp along with reference strains of B, C, and F1 representative HIV-1M subtypes. (B) Genomic structure of the CRF99_BF1. Breakpoint positions according to HXB2 genome numbering system are indicated. The blue color stands for subtype B, the green color stands for subtype F1, and the brown color for subtype C.
