Phylogenetic analysis of a subset of dengue virus 1 E gene sequences within genotype III that are most closely related to those sampled from Wenzhou, Zhejiang Province, and Wuhan, Hubei Province, China, during 2014. The viruses identified in this study were designated as the Wenzhou-human and Wuhan-human sequences, respectively (GenBank accession nos. KR024705–KR024708). Bootstrap values (>70%) are shown at relevant nodes. Bold text indicates sequences obtained in this study. The tree is midpoint rooted for clarity. Scale bar indicates nucleotide substitutions per site.
