Evaluation of lockdown and social distancing policy intensity (left panel) and timing (right panel) in Wuhan by June 1, 2020. For the policy intensity, the current policy (red) were considered, together with three other scenarios: The overall response intensity decreased to 70% (green), all of the response intensity decreased to 70% after Level I response (light blue), and all of the response intensity decreased to 70% after Level II response (purple). For the policy timing, the current policy (red) was considered, together with two other scenarios: a 7-day delay of the intervention (green) and a 14-day delay of the interventions (blue).
