Reproduction number estimates for the Omicron subvariants. (a) Estimates of effective reproduction numbers for each Omicron subvariant (e.g. BA.1, BA.2, BA.4, BA.5 and XG). (b) Estimates of relative effective reproduction numbers to the Delta variant for each Omicron subvariant. The estimates of BA.1 and BA.2 were pooled values, whereas those of BA.4, BA.5 and XG were directly retrieved from Kimura et al.3. The dots and error bars show the estimated mean and 95% confidence interval, respectively
