Contact tracing is a fundamental approach to public health practice and has the aim of reducing the number of secondary cases of an infectious disease in an outbreak and the consequences of infection in subsequent cases.
In this next recovery phase contact tracing will seek to achieve its aim of reducing transmission of the infection by identifying contacts who may have come into contact with the person with COVID-19 at the time the case was infectious.
