Scatter Plot from Scientific Research

Maximum clade credibility tree of 241 CHIKV genomes from the ECSA genotype, including 61 new CHIKV genomes (Ceara 2022, magnified section) from Ceara state generated in this study. Tips are coloured according to the source region or state of each sample. A strict molecular clock approach was used for generating the time-rooted tree. Posterior probability scores are shown next to key well supported nodes. Dates at key nodes are the estimated date of divergence from a common ancestor, with Bayesian credible intervals.
