Phylogenetic analysis of WEEV strains from Rio Grande do Sul state, Brazil, and reference sequences. A) Regression of sequence sampling dates against root-to-tip genetic distances in a maximum likelihood phylogeny of the WEEV strains. Sequences are colored according to geographic source. Line indicates the correlation; shading indicates 95% CIs. B) Effective population size of WEEV through time using the Skygrid model. Thin blue lines represent 95% Bayesian credibility interval, and the thick blue line represents the posterior median. Vertical dotted lines indicate the best estimates for the time of the root of the tree (left) and the upper highest posterior density (right). WEEV, western equine encephalitis virus.
