Maximum-likelihood phylogenetic analysis for DENV-2 cosmopolitan genotype, Brazil. A) Midpoint rooted tree shows the evolutionary relationships of the complete genome sequence from the DENV-2 cosmopolitan genotype identified from a patient in Goiás state, Brazil (orange circle), and 1,089 publicly available sequences from GenBank. Scale bar indicates nucleotide substitutions per site. Colors represent different sampling locations. Blue highlighting shows area enlarged in panel B. B) Time-resolved maximum-likelihood tree showing the blue highlighted area from the larger tree in panel A. Colors indicate geographic location of sampling. Support for branching structure is shown by bootstrap values at key nodes. DENV-2, dengue virus serotype 2.
