Contact tracing is an effective public health measure for the control of COVID-19. The prompt identification and management of the contacts of COVID-19 cases makes it possible to rapidly identify secondary cases that may arise after transmission from the primary cases.
Measures to prevent transmission in healthcare facilities are an immediate priority in order to slow the demand for specialised healthcare; safeguard risk groups; protect healthcare workers and minimise the export of cases to other healthcare facilities and the wider community.
The use of face masks in public may serve as a means of source control to reduce the spread of the infection from infected individuals who have not yet developed symptoms or who remain asymptomatic.
