A close contact is now defined as living with someone who has Covid-19 or being being formally notified by NSW health they are a close contact. If your exposure was someone outside of your household, please assess your own personal risk in accordance with the guidance shown here.
If you find out that you are a close contact, you should isolate as much as possible from the person with Covid-19. If you have no symptoms, you do not have to self isolate, but you should be aware that you are at increased risk of COVID-19 and need to take steps to protect people around you.  You should not visit the practice for at least 7 days after the last family member tested positive, unless you have spoken with a doctor.
If you develop any symptoms, you should get tested and isolate for 7 days from the day of the test if it is positive.
