Molecular Clock of DENV-2. DENV-2 divergence time was estimated using year of isolation (scale used in the tree) as calibration points under the strict molecular clock model using GTR + Γ + I parameters. Posterior Probability (PP) values are indicated for each node, and the blue bars represent the extent of the 95% highest posterior density (HPD) intervals for each divergence time. American genotype (Subtype V) and Colombian isolates belonging to this clade are show in red. American/Asian genotype (Subtype IIIb) and Colombian isolates belonging to this clade are show in blue.
