Figure 1
Figure 1. Maximum-likelihood phylogenetic tree of Mayaro virus sequences from Peru compared with global Mayaro virus sequences. All sequences were mapped onto the phylogeny by sampling country and genotype using the ggtreeExtra R package (The R Project for Statistical Computing, https://www.r-project.org). Bootstrap values >80% are shown; scale bars represent nucleotide substitutions per site. Mayaro virus sequences indicate the strains circulating in Peru obtained in this study belong to genotype D and are organized into 2 independent monophyletic clades (left subtrees). NA, not available; s/s, substitution per site.
