Monitoring and evaluation

Governments can use predefined performance targets to determine the efficacy of its contact tracing program. These metrics can be used in tandem with broader metrics tracking cases and mortality rate to consider loosening and tightening social restrictions.

Example metrics and targets for contact tracing

Possible criteria to loosen restrictions

Possible criteria to tighten restrictions

Other performance metrics
