- Being a close contact with a person who has COVID-19 can occur in different settings and depends on different situations such as how long you were together, how close you were, what happened during the interaction, if protective measures such as physical distancing were followed, or in other special circumstances
- If you are identified by public health as a close contact, you need to self-monitor for symptoms consistent with COVID-19 for 14 days after being exposed to COVID-19. Contacts need to get tested if they develop any COVID-19 symptoms.
- Some close contacts also need to self-isolate. If you have already had COVID-19 or if you have been partially or fully immunized, you may not need to self-isolate. Public health will help you decide which steps to take based on how you were exposed to COVID-19, the dates of your first and second dose of vaccine, or when you recovered from COVID-19.
A close contact is generally someone who has been near a person with COVID-19 for at least 15 minutes when health and safety measures were not in place or were insufficient. Health and safety measures include things such as physical barriers or physical distancing of at least 2 metres. If you are wearing a non-medical mask, you may still be considered a close contact. Some interactions that are less than 15 minutes can also be considered close contact.
Close contact can occur when people have intimate contact, share a room, a house or a workplace, or are in a crowded place where health and safety measures aren’t always being used. You can also be considered a close contact if someone with COVID-19 sneezes or coughs on you. In other situations public health will need to assess what happened, and decide if someone is a close contact.
You may be a close contact even if you interacted with a person up to 2 days before they showed symptoms.
Some people are asymptomatic and still test positive. You may also be a close contact if you were around them up to 2 days before their positive test.
If public health decides you are a close contact, you have to follow their advice.
