(a) Relative frequency of the serial intervals, based on eight observed transmission events, (b) Relative frequency of the serial intervals, based on 8 observed transmission events and 27 reconstructed transmission events. The black line shows the distribution with any infector, mean = 7.4 days [95% CI: 6.5, 8.6]. The grey line shows the distribution with only terminally ill infectors, mean = 9.2 days [95% CI: 7.9, 10.6]. (c) Average effective reproduction number (R_e(t)) per day (dots) and 95% bootstrap percentile confidence interval (bars).
