You may be identified as a contact of a case in various ways: through the confirmed case itself, through public health, your employer, your child’s school or daycare, etc.

You are a contact of a case in the following situation: you have been in contact with the case within 48 hours before the onset of symptoms of the case (or before the date of collection if the case had no symptoms) until the case is isolated.

The following recommendations must be followed unless otherwise advised by public health authorities.

If you develop symptoms, you must follow the instructions on the page Instructions for people with COVID-19 symptoms.

If in doubt, call 1-877-644-4545 or consult the Self-Care Guide. You can also contact the Info-Santé 811 hotline (24/7 phone consultation service) if you need advice about your health (e.g., if your symptoms persist).

Healthcare workers

If you’re a healthcare worker, contact your workplace to receive instructions on when and how to end your isolation and return to work.

Self-isolating means staying at home

For a high-risk contact, self-isolation is required even if the contact does not develop any symptoms and even if they get a negative test result.

  • Do not go to school or work or to an early childhood or daycare centre or any other public place, such as a store, and do not take public transport.
  • Do not go out for a walk.
  • If you have no one who can help you by picking up your groceries and medications, have your supermarket and pharmacy orders delivered and stay at least two metres away from the delivery person.
  • Allow no visitors in your home.
  • You can go outside on your balcony or in your private yard, making sure that you are 2 metres away from any other person.
  • If you live with others who do not have COVID‑19, avoid contact with them:
    • Keep a distance of at least 2 metres between yourself and others. Cover your nose and mouth if you need to be closer than 2 metres from someone.
    • Remain alone in one room of the house as often as possible.
    • If possible, eat and sleep alone in a single room of the home.
    • If possible, use a bathroom reserved for you alone. Otherwise, disinfect after each use.
    • Air out the house and your room often by opening a window, weather permitting.

No document (e.g., certificate) or procedure should be required after a period of isolation. Once isolation is over, you can resume your activities if the other conditions are met.
