Reconstructed genotyping phylogeny of dengue virus type 2 (Orthoflavivirus denguei) and Chikungunya virus. (A) Maximum likelihood phylogenetic reconstruction of DENV-2 using partial sequences (n = 58) of the NS5 gene, including sequences (n = 22, red tips) generated in this study from clinical samples. (B) Maximum likelihood phylogenetic reconstruction of CHIKV using partial sequences (n = 36) of the envelope gene, including sequences (n = 11, pink tips) generated in this study from clinical samples. Numbers along branches represent Ultrafast bootstrap values (only for the main branches, to maintain clarity).
