Phylogenetic tree based on the full E gene of the reference DENV strains. DENV 3 was used as out-groups. The strains are denoted by the strain name, country of isolation, year of isolation and GenBank accession number. “NA” means “not available.” DENV serotypes 1–4 are shown as D1–D4, respectively. An asterisk is used to denote the new isolate identified in this study.
