Fig. 6From: Modeling of suppression and mitigation interventions in the COVID-19 epidemicsThe epidemic dynamics with a combined intervention of suppression and mitigation for different intervention time t0. a t0=30; b t0=20; c t0=10. The right column corresponds to the effective reproduction number Rt calculated by the intervention strategies. Parameters are set as αs=0.3 and αm=0.7. Other parameters are the same as Table 1Back to article page
