COVID-19 Exposed

Last updated: November 17, 2022

NOTE: Ontario has updated public health guidance to manage COVID-19 during the upcoming flu and respiratory illness season. 

If you are having difficulty breathing or experiencing other severe symptoms, call 9-1-1 immediately. Advise them of your symptoms, travel history or exposure risks.

Visit the provincial webpage, Public health measures and advice to learn how to protect yourself, your family and your community from COVID-19 and other respiratory illnesses.

Stay home when sick

If you are sick with COVID-19 or another respiratory illness, stay home to prevent spreading the virus to others, except to seek testing or medical care if required.

You should stay home until all of the following apply to you:

  • your symptoms have been improving for at least 24 hours (or 48 hours if you had nausea, vomiting and/or diarrhea)  
  • you do not have a fever
  • you do not develop any additional symptoms

When your symptoms are improving and you are no longer isolating at home, doing the following can provide extra protection against the spread of COVID-19 and other respiratory viruses circulating in the community.

For 10 days after your symptoms started:

  • wear a well-fitted mask in all public settings
  • avoid non-essential activities where you need to take off your mask (for example, dining out)
  • avoid non-essential visits to anyone who is immunocompromised or may be at higher risk of illness (for example, seniors)
  • avoid non-essential visits to highest risk settings in the community such as hospitals and long-term care homes

If you work in a high risk setting

If you have symptoms of COVID-19 or have tested positive for COVID-19 and work in a high-risk setting (such as a hospital, a long-term care home, or a retirement home), you should speak with your employer and follow your workplace guidance for return to work.

COVID-19 treatments

COVID-19 treatments are available for free by prescription to individuals with COVID-19 symptoms and a positive test result, who are at higher risk of developing severe illness. More information is available on the provincial webpage, COVID-19 testing and treatment.

To determine if you might be at higher risk and should be assessed for treatment, use the provincial COVID-19 antiviral treatment screener.
