Notifying contacts helps to control the spread of the virus by quickly informing people who may have been exposed to a person who has tested positive for COVID-19. If you contract COVID-19 or are exposed to someone who has tested positive, you can protect other people from getting sick by notifying your close contacts (anyone who has been within six feet of you for at least 15 minutes).
If you test positive for COVID-19 and have had symptoms, you should notify all the people you have had close contact with, starting from two days before your symptoms started up until you tested positive. If you don’t have symptoms, you should notify anyone who you were in close contact with in the two days before you got your positive test.
