Phylogenetic relationships of 3 complete coding regions of Nigerian dengue virus type 2 (DENV-2) isolates obtained from febrile patients in Ibadan, Nigeria, during the 1966 rainy season. A total of 15 sylvatic DENV-2 genomes (shaded) were compared with human isolates of DENV-2 and representatives of DENV-1, DENV-3, and DENV-4. Phylogeny was inferred by using Bayesian analysis, and all horizontal branches are scaled according to the number of substitutions per site. Bootstrap values are shown for key nodes.
