Fig. 4From: Chikungunya virus infection: molecular biology, clinical characteristics, and epidemiology in Asian countriesEvolutionary analysis of the complete genome of the CHIKV ECSA lineage. Bayesian time-scale tree of 169 genomes of the CHIKV ECSA lineage based on the strict clock model. The 95% HPD values of the most recent common ancestors (tMRC) are shown beside the nodes. The colored square of each strain corresponds to the amino acid mutations specific for the CHIKV ECSA lineage.
