Figure

Figure. Phylogenetic analysis of dengue virus type 2 strains obtained from 2 patients who returned to Japan from Sri Lanka in June 2017 (arrows) and a comparison with reference sequences from GenBank. Virus lineages are shown at right. Phylogenetic tree was constructed by using the neighbor-joining method. The maximum composite likelihood method was used, and the rates among sites were uniform. These analyses were performed using MEGA7 (http://www.megasoftware.net). Scale bar indicates nucleotide substitutions per site.
