Most recent lineages based on data last downloaded on 2023-07-28

We currently catalog more than 100 officially designated dengue virus lineages across all four serotypes.

Use Genome Detective to assign lineages to your sequences.

The global distribution and phylogenetic tree of each genotype, major lineage, and minor lineage can be visualized by clicking the names in the table. If an exact sequence you expect to see here seems missing, it may not have been released yet on GenBank, or it may not be included in our build.
