From: Phylogenetic history demonstrates two different lineages of dengue type 1 virus in Colombia
Evolutionary relationships of DENV-1. Phylogenetic tree of 126 DENV-1 isolates worldwide. It was computed using the Maximum Likelihood method. The optimal tree with the sum of branch length = 0.596 is shown. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. Significant bootstrap values (≥ 50) are indicated. Clade supporting the putative lineage 2 is show in red. Colombian isolates are in blue. There were a total of 221 positions in the final dataset. Phylogenetic analyses were conducted in PAUP*
