Fig 7. Alternative scenarios: Lifting combinations of different policies.

Fig 7

This figure plots the trends in observed and counterfactual number of cumulative infections under several alternative scenarios from (A) Jan 1,2020 to Mar 15,2020, and from (B) Jan 1 to July 15. Data are presented as the median (solid line) and IQR (shading) of estimates (200 simulations). “No Policy” denotes the scenario in which no anti-contagion policies have been put in place. “Travel Restriction” denotes the case where only intercity travel bans were implemented after January 23. “TR+Lockdown” denotes the scenario in which both intercity travel restrictions and city lockdown were implemented. “TR+Lockdown+Testing&Treatment(TT)” denotes the baseline scenario in which all three policies have been implemented from January 23 to March 15.
