Symptoms and treatments of COVID-19

Symptoms of COVID-19

Those who are infected with COVID-19 may have little to no symptoms. You may not know you have symptoms of COVID-19 because they are similar to a cold or flu.

Symptoms have included:

  • cough

  • fever

  • difficulty breathing

  • pneumonia in both lungs

In severe cases, infection can lead to death.

Symptoms may take up to 14 days to appear after exposure to COVID-19. This is the longest known incubation period for this disease.

Recent evidence indicates that the virus can be transmitted to others from someone who is infected but not showing symptoms. This includes people who:

  • have not yet developed symptoms (pre-symptomatic)

  • never develop symptoms (asymptomatic)

While experts know that these kinds of transmissions are happening among those in close contact or in close physical settings, it is not known to what extent.


If you or your child become ill

If you are showing symptoms of COVID-19, reduce your contact with others:

  • isolate yourself at home for 14 days to avoid spreading it to others

  • if you live with others, stay in a separate room or keep a 2-metre distance


  • visit a health care professional or call your local public health authority

  • call ahead to tell them your symptoms and follow their instructions


Children who have mild COVID-19 symptoms are able to stay at home with a caregiver throughout their recovery without needing hospitalization. If you are caring for a child who has suspected or probable COVID-19, it is important to follow the advice for caregivers. This advice will help you protect yourself, others in your home, as well as others in the community.

If you become sick while travelling back to Canada:

  • inform the flight attendant or a Canadian border services officer

  • advise a Canada border services agent on arrival in Canada if you believe you were exposed to someone who was sick with COVID-19, even if you do not have symptoms

  • this is required under the Quarantine Act

  • the Canada border services agent will provide instructions for you to follow.

Diagnosing coronavirus

Coronavirus infections are diagnosed by a health care provider based on symptoms and are confirmed through laboratory tests.


Treating coronavirus

Most people with mild coronavirus illness will recover on their own.

If you are concerned about your symptoms, you should self-monitor and consult your health care provider. They may recommend steps you can take to relieve symptoms.

Vaccine

If you have received a flu vaccine, it will not protect against coronaviruses.

At this time, a vaccine or therapy to treat or prevent this disease has not yet been developed. However, the COVID-19 pandemic has resulted in a global review of therapies that may be used to treat or prevent the disease.


About coronaviruses

They are a large family of viruses. Some cause illness in people and others cause illness in animals. Human coronaviruses are common and are typically associated with mild illnesses, similar to the common cold.

COVID-19 is a new disease that has not been previously identified in humans. Rarely, animal coronaviruses can infect people, and more rarely, these can then spread from person to person through close contact.
