Figure 2: Comparison of cumulative case data with model projections for the 2023 Mpox epidemic in Beijing . Cumulative case data (black lines) between 2023-06-21 and 2023-09-30, and comparison with projections from the individual-instant heterogeneity model under homogeneous transmission (A~C,k =1~4) and heterogeneous transmission (D,k =0.5). Colored lines represented the medians of simulated data under various levels of effective reproduction numberR e. In simulation, we used the gamma-distributed serial interval with the mean = 5.6 days and SD = 1.5 days and repeated for 5000 times.
