A Posterior distribution of the basic reproduction number and intervention efficacy combined. B Marginal posterior distribution of the basic reproduction number. C Marginal posterior distribution of the intervention efficacy for each outbreak, in chronological order. Dashed lines indicate 95% confidence intervals. Purple/blue regions in plot A represent low density pairs of intervention efficacy and \({R}_{0}\) values (i.e. pairs with relatively few values found in the posterior distribution), while yellow regions represent high density pairs (i.e. pairs with relatively many values found in the posterior distribution)
