Fig. 4

Epidemic curves of scenarios simulating resuming of in-person education with different levels of personal protection based on mask-wearing and physical distancing (from June 21, 2020, to June 21, 2021). The panel shows estimates from a scenario with no personal protection (left), with mask-wearing and physical distancing performed by 50% (center) and 70% (right) of the school population. In the graphs, the yellow bars are the mean values of the simulation, and the green and red bars are the 95% credible interval. The orange line represents the reported number of cases until November 20, 2020. The gray bar represents the number of cases reported until June 21, 2020
