Phylogenetic tree of dengue virus 3, subtype III group A, group B, East Africa, and Latin America. Tree is based on 966-base region spanning positions 179–1,145 on the viral genome, capturing a portion of the C gene, all of pre-M/M gene and a portion of the E gene. Nucleotide substitutions conserved within each dengue virus 3, subtype III group (group A, B, East Africa, and Latin America) are listed in Table 3. DHF, dengue hemorrhagic fever.
