Phylogenetic dendrogram of 5 Dongguan CHIKV strains.
This dendrogram was constructed using the neighbor-joining method based on the alignment of E1 gene sequences. The bootstrap values from 1000 pseudoreplicates for major lineages within the tree are shown as percentages. Dongguan CHIKV strains are marked using the symbol ▴.
