FIG 6.

Maximum clade credibility (MCC) tree of the cluster including one sequence of the Contamines-Monjoie transmission chain (EPI-ISL-410486). Branch colors indicate the most probable location of the MRCA, and node labels indicate the posterior probability supporting the estimated MRCA location. Node support values are indicated by node size (only nodes with PP of ≥0.8 are considered well supported). The scale axis represents estimated dating of the MRCA for each cluster, and label spacing defines exactly 9.16 days from the most recent sample included in the analysis. The red star indicates the sequence associated with the Contamines-Monjoie cluster, and “V” indicates the presence of the G251V mutation in ORF3a protein.
