Close and casual contacts are determined after a NSW Health official carries out a risk assessment on the locations where a person with COVID-19 has visited whilst they are infectious. Settings might include public transport, residential homes, restaurants, pubs, cafes and other locations where the person has come into contact with people. Factors involved in the risk assessment include the time spent at the location, activities undertaken, the number of people present, and the size and layout of the setting or location.
If you are a close contact of a person with confirmed COVID-19 infection, you need to be isolated for 14 days after you last saw that person and seek immediate testing. You must self-isolate regardless of the test result. Self-isolating applies to all close contacts, even if you are well. It is important to monitor your health and report any symptoms as early as possible and get tested if new symptoms develop.
If you live in the same household as, or are identified as a close social contact, of the infected person, you should be tested again on day 10-12 of your isolation period. You should continue to self-isolate until you have completed your 14-day isolation period and have received a negative test result.
