NPI groups | Specific NPIs | Coding schema |

Any effort scenario: NPIs are binary variables, considered “present” as long as any (non-zero) effort is made. Maximum effort scenario: NPIs are binary variables, considered “present” only if the maximum effort is made. For example, an intervention X has levels 0–3. A record at level 2 is converted to 1 under any effort and 0 under maximum effort scenarios. |
International travel restrictions | International movement restriction | |
Economic policies | Income support; debt/contract relief for households | |
Health systems policies | Public information campaign; testing policy; contact tracing |
