Phylogenetic tree of DENV-2. The maximum-likelihood tree was constructed based on the complete envelope gene sequences generated during this study and retrieved from GenBank. Sequences from Pakistan are highlighted in red. Figures on branches are bootstrap percentages. Only bootstrap values more than 75% are shown on the major nodes.
