Model simulations showing the effect of a hand hygiene intervention across different levels of intervention coverage in the community. At each level of coverage of the intervention, the stochastic model was simulated 100 times. Panels A and B show the median values for the cumulative incidence (proportion infected) and protective efficacy, respectively, where D₁ represents the disease risk in the intervention group, D₀ represents the disease risk in the control group, and D_0* represents the disease risk in a separate population where there is no intervention (see Figure 1 for details).
