Figure 6

Maximum clade credibility tree of CRF89_BF Pr-RT sequences. Branch colors indicate, for terminal branches, country of sample collection or, if known, of origin of the individual, and for internal branches, the most probable location country of the subtending node, according to the legend on the left. Nodes supported by PP ≥ 0.95 are indicated with filled circles. Most probable countries at the root of the tree and of the three major clusters are indicated, together with PP supporting the locations and tMRCA (mean values, with 95% HPD intervals in parentheses).
