Main Article

Figure 7

Bayesian time-scaled phylogeny of enterovirus D68, subgenotype A2, from report on national surveillance of enterovirus D68 upsurge, France, 2024. Phylogeny created using BEAST version 2.6.3 (https://beast.community). Subtree focusing on the most recent strains of subgenotype A2 was extracted from the complete time-calibrated phylogenetic tree. The estimated ages of the most recent common ancestors from the root of each clade to the year 2024 are indicated. Red stars at nodes indicate posterior probabilities >0.9, star sizes are proportional to posterior probability (larger symbols indicate values closer to 1). Colors at right indicate country of origin for each strain. Blue dots indicated at the taxon names indicate sequences generated in this study in 2024. GenBank accession numbers are provided.
