WHO has defined four transmission scenarios for COVID-19:
- countries with no cases (No Cases)
- countries with 1 or more cases, imported or locally detected (Sporadic Cases)
- countries experiencing cases clusters in time, geographic location and/or common exposure (Clusters of cases)
- countries experiencing larger outbreaks of local transmission (Community transmission)
The Table describes the preparedness, readiness and response actions for COVID-19 for each transmission scenario. Hyperlinks to existing WHO Technical Guidance are provided.
