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.
COVID-19 specific symptoms can vary from person-to-person and may take up to 14 days after a COVID-19 exposure to appear.
Other symptoms that may be associated with COVID-19 include:
Rarely, children can get an inflammatory condition that impacts the blood vessels, called vasculitis. It can present with prolonged fever, abdominal pain, red eyes, nausea, vomiting, diarrhea, and rash. It needs medical attention.
If you have any of the symptoms above, you should stay home (self-isolate) while you are sick. Stay home until you have no fever and your symptoms are improving for at least 24 hours (or 48 hours if you have gastrointestinal symptoms such as vomiting and/or diarrhea).

Long COVID, or post-COVID-19 condition (PCC), is when someone who had COVID-19 has symptoms and/or health problems (that are not from another health condition or illness) 12 weeks or more after their original COVID-19 infection. These symptoms and/or health problems can be new, the same, or have come back. Even though they may have COVID-19 symptoms, people with long COVID no longer have the virus and cannot spread it to others.
In Canada, as of August 2022, almost 15% of adults (approximately 1.4 million) who got COVID-19 said they continued to have symptoms 3 months or more after their original COVID-19 infection.
Long COVID can be serious. Over 20% of adults in Canada with long COVID say their symptoms impact their ability to do daily activities. 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 develop long COVID. We do not know why some people with COVID-19 develop long COVID, while others do not. Long COVID is more common in adults, particularly women, 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 go up with each new COVID-19 infection.
Talk with a health care provider who can assess you based on your signs and symptoms.
There are a wide range of symptoms of long COVID. Symptoms can be different for everyone, especially between adults and children. 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.
You can lower your risk of getting COVID-19 by staying up-to-date with the recommended COVID-19 vaccines. Studies show that people who are vaccinated 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.
