Phylogenetic analysis of DENV-2 strains isolated in French Polynesia, February 2017 (n = 3)

DENV: dengue virus.

The evolutionary history was inferred by using the maximum likelihood method based on the Kimura 2-parameter model [24]. The percentage of trees in which the associated taxa clustered together is shown for values higher than 90 next to the branches (1,000 replicates). Evolutionary analyses were conducted in MEGA7 [25]. Each strain is labelled by country _ date of origin / GenBank accession number. The DENV-2 strains isolated in French Polynesia in February 2017 are marked with a black circle.
