Fig 1. Phylogenetic tree of DENV-2 based on the whole genome.

Fig 1

It shows the relationship of the 54 virus strains from different sources, the MT 180479 strain from Sri Lanka, and the 5 isolates (*) of DENV-2 in this study. The 5 isolates in this study and the MT 180479 formed a new clade whereas the strains previously circulating in Sri Lanka belonged to an old clade. The representative strains of each genotype obtained from GenBank are named by country-origin, strain name, year of isolation, and GenBank accession number.
