WHO has defined four transmission scenarios for COVID-19:

Critical preparedness, readiness and response actions

WHO has defined four transmission scenarios for COVID-19:

  1. Countries with no cases (No cases);

  2. Countries with 1 or more cases, imported or locally detected (Sporadic cases);

  3. Countries experiencing cases clusters in time, geographic location and/or common exposure (Clusters of cases);

  4. Countries experiencing larger outbreaks of local transmission (Community transmission).

This document describes the preparedness, readiness and response actions for COVID-19 for each transmission scenario.

Responding to community spread of COVID-19

This document provides technical guidance for government authorities, health workers, and other key stakeholders to guide response to community spread. It will be updated as new information or technical guidance become available. For countries that are already preparing or responding, this document can also serve as a checklist to identify any remaining gaps.

Operational considerations for case management of COVID-19 in health facility and community

This document is intended to guide the care of COVID-19 patients as the response capacity of health systems is challenged; to ensure that COVID-19 patients can access life-saving treatment, without compromising public health objectives and safety of health workers.

It promotes two key messages:

  1. Key public health interventions regardless of transmission scenario; and

  2. Key action steps to be taken by transmission scenario to enable timely surge of clinical operations.

Prioritized Laboratory Testing Strategy According to 4Cs Transmission Scenarios

Diagnostic testing for COVID-19 is critical to tracking the virus, understanding epidemiology, informing case management, and to suppressing transmission. This document describes the strategic use of diagnostic testing in different transmission scenarios of the COVID-19 outbreak, from no cases to community transmission, including how testing might be rationalized when lack of reagents or testing capacity necessitates prioritization of certain populations or individuals for testing.”
