Phylogenetic tree based on the complete coding sequences of 49 DENV-2 strains. Each strain was abbreviated as the GenBank accession number followed by the country and year of isolation. The numbers at the nodes revealed bootstrap support for that node (bootstrap replications was 1000). The DENV-2 strain sequenced in this study is marked with a solid circle (●). The complete sequence of DENV-1 (US/Hawaii/1944, EU848545) was used to root the tree
