(A) Epidemic curve (based on confirmed date) with colored boxes indicating dominant variants at each time period, (B) Effective reproduction number (\({R}_{t}\), or R on the chart), red line was estimated from the daily number of cases, (C) time-varying dispersion parameter (\({k}_{t}\), k on the chart), (D) the proportion of cases infecting 80% (\({P}_{80}\), Prop_80 on the chart), and (E) the proportion of cases who did not spread to anyone (\({P}_{0}\), Prop_0 on the chart) for each generation of transmission in Yamagata, Japan between 2020 November 1 and 2022 January 19. In Panel (A), (1) ~ (5) indicates each wave. In Panel (B–E), the shaded areas show the 95% CrI. SOE: State of emergency, G1: first-generation, G2+: second-generation or later, All: All generation.
