Circulation of DENV-3 genotypes in 16 countries across three regions in Asia from the 1950s to 2023. DENV-3 envelope sequences were collected from GenBank and categorized by genotype and year for each country. The numbers of DENV cases were aggregated for sequences collected prior to 1989 and for those collected between 1990 and 1999. Differently colored dots represent the genotypes indicated in the legend, with the dot size corresponding to the number of sequences.
