If you have symptoms of any respiratory viral infection, take the Ontario Ministry of Health’s COVID-19 Self-Assessment for recommendations on what to do next. For more information, visit the Provincial website.
Stay home until you have no fever and symptoms are improving for at least 24 hours (or 48 hours for gastrointestinal symptoms such as vomiting and/or diarrhea).
If you have COVID-19 or other respiratory virus symptoms and you are at a higher risk of severe illness, you may seek COVID-19 testing and treatment, if eligible. You can take a Rapid Antigen Test if you have one. COVID-19 treatment must be taken within the first 5-7 days from the start of your symptoms.
COVID-19 and other respiratory viruses, such as the flu, share some common symptoms.
Clinical Assessment Centres are able to assess, test and provide treatment options to eligible individuals with COVID-19, cough, cold and flu symptoms. Some centres can also assess children.
COVID-19 specific symptoms can vary from person-to-person and may take up to 14 days after a COVID-19 exposure to appear.

Long COVID, or post-COVID-19 condition (PCC), is when someone has symptoms and/or health problems three or more months after a COVID-19 infection that cannot be explained by anything else. Even though they may have COVID-19 symptoms, people with long COVID no longer have the virus and cannot spread it to others.
As of June 2023, 3.5 million Canadian adults (almost 12 per cent) report having symptoms three months or more after their original COVID-19 infection.
Long COVID can be serious. Over 20 per cent of adults in Canada with long COVID say their symptoms impact their ability to do daily activities. Almost 80 per cent say they experienced symptoms for six months or more, and almost half say that they experienced symptoms for over a year and missed about 20 days of work or school.
Anyone who gets COVID-19 can get long COVID. We do not know why some people with COVID-19 get long COVID, while others do not. Long COVID is more common in adults, particularly women and adults with pre-existing health conditions, but children can also get it.
There is a higher chance of getting long COVID if you got very sick with COVID-19 and needed to go to the hospital. However, even people with a mild or moderate COVID-19 illness can get long COVID, as well as people who had no symptoms. The risk of long COVID can also increase anytime you get another COVID-19 infection.
Talk with a health care provider who can assess you and review your symptoms.
There are a wide range of symptoms of long COVID. Symptoms can be different for everyone, especially between adults and children. The symptoms can also change over time. Common symptoms include:
People with long COVID may continue to have their original symptoms or get new symptoms which can change or get worse. If you have long COVID, you can get COVID-19 again. Get tested if you have new symptoms of an infection and are eligible. There is currently no specific treatment for long COVID, but a health care provider can give you advice and support on how to manage your symptoms.
The best way to prevent long COVID is by not getting a COVID-19 infection. It may be difficult to prevent all infections, but there are things you can do to lower the risk of infection.
You can lower your risk by getting vaccinated. Studies show that people who are vaccinated with two or more doses are less likely to get long COVID and that getting vaccinated continues to protect people even after having a COVID-19 infection.
Newer research is showing that antiviral treatment taken at the beginning of a COVID-19 infection may also lower the risk of getting long COVID. Find out if you are eligible for treatment.
Following public health measures, such as wearing a mask, especially if you or people around you are at higher risk or have a health condition, continues to protect against COVID-19 and prevent long COVID.
