III. The Role of Tracing While Waiting for a Cure and a Vaccine

Locating all the people that were in close contact with a person confirmed with COVID-19, at least since the onset of their disease and ideally some days before that.

Involves conducting interviews with each COVID-19 (+) patient and informing individuals of possible exposure on mitigation measures or testing

These contacts should ideally be placed in quarantine for at least 14 days (the upper bound of the incubation period of COVID-19), either in their homes or in a specific facility.

This also implies monitoring/following-up of the contacts to monitor for symptoms and signs of infection, and testing then to check for disease infection

The effectiveness depends on both high speed and the accuracy.
