Estimated relative Reof each viral lineages, assuming a fixed generation time of 2.1 days. The relative Reof EG.5.1 is designated to 1 (horizontal dashed line). The graph includes: the posterior distribution enclosed within the 99% Bayesian confidence interval (CI; violin), 95% CI (line), and posterior mean (dot). BA.2.86 and its sublineages, except for those with amino acid mutations in S (e.g., JN.1), are summarized as BA.2.86. The global average values estimated by a hierarchical Bayesian model10are presented. See alsoFigure S1B.
