Maximum-likelihood phylogram of the envelope gene (1,485 nt) of DENV-1 strains detected in Osaka, Japan, 2019 (arrow), Africa (black squares), and reference strains. Based on Bayesian information criteria, the Tamura-Nei plus gamma model was used to construct the phylogram. Numbers at the nodes indicate the bootstrap support values, which are expressed as a percentage of 1,000 replicates (values <80% are omitted).

Numbers at the nodes indicate the bootstrap support values, which are expressed as a percentage of 1,000 replicates (values <80% are omitted). Each strain is identified by strain name, 2-letter country name abbreviation (country exported from/to, in the case of travelers), and detection year; accession numbers are shown in parentheses. Genotype I–IV branches are condensed for space. Scale bar indicates genetic distance (nucleotide substitutions per site).
