Here’s a quick look at the basics of what you should know about the virus, what to do in case of suspected infection and how to protect yourself.

What is COVID-19?

COVID-19 is the name given to the current pandemic “coronavirus disease 2019”, caused by the recently discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

SARS-CoV-2 is a novel strain of coronavirus — a family of viruses that can cause a range of illnesses associated with infection of the upper respiratory tract, from the common cold to pneumonia and bronchitis. The SARS outbreak in 2003 was also caused by a coronavirus.

SARS-CoV-2 was first documented in Wuhan, China.

The first presumptive case of infection in Ontario was identified on Jan. 25.

How is this strain different?

SARS-CoV-2 possesses unique traits for a coronavirus, often associated with high communicability, including a delayed incubation period that can allow carriers to transmit the virus without realizing they are infected. As well, because much is still being learned about this strain, successful diagnostic and treatment methods are still being developed.

How does it spread?

Coronaviruses spread mainly from person to person through contact of common surfaces such as clothes, utensils, and furniture.

The risk of contracting a severe case of the disease is higher if your immune system is compromised due to old age or chronic illness.

What are the symptoms?

Symptoms are usually flu-like and can range from mild to severe. They include fever, cough, sore throat, difficulty breathing, malaise, fatigue, chills and diarrhea.

Complications from COVID-19 can result in serious conditions like pneumonia or kidney failure and in some cases, death.

The Ontario government has a self-assessment tool available online.

Can COVID-19 be treated?

There is no singular treatment for coronaviruses and very few if any vaccines that protect against them. Most people with common human coronavirus illnesses recover on their own.

To manage symptoms, the government recommends taking the same measures as you would with a common cold: drink plenty of fluids, get lots of rest and sleep as much as possible and try using a humidifier or take a hot shower to help with a sore throat and cough.


Who to call if you think you have the virus

Unrelated to travel:

If you develop symptoms of COVID-19, call Telehealth Ontario for medical advice at 1-866-797-0000 for medical advice. You can also contact your local public health unit. Click here to find a public health unit close to you: Public Health Units.

Be sure to tell them your symptoms and travel history including any countries you visited.

Online self-assessment tool

The Ontario government has set up an online self-assessment tool here.

The province is urging people to use this first before visiting an assessment centre in order to cut down on volume and ensure those who are most at risk are getting tested.

Public health COVID-19 test results hotline

Toronto Public Health has a COVID-19 test results hotline should you be tested for the illness.

You can call 416-338-7600 between 8 a.m. and 8 p.m. seven days a week.

During and after travel:

  • If you become sick while travelling or after you get back, avoid contact with others and call Telehealth or contact your local public health unit. Tell them your symptoms, where you have been travelling or living and if you had direct contact with animals or with a sick person.
  • If you feel sick during your flight or upon landing, tell a flight attendant or a Canada border services agent.


After return from an affected area:

  • You may need to self-isolate for 14 days because you may have been exposed to COVID-19. Staying home and limiting your contact with others will help prevent further spread.
  • If your symptoms feel worse than a common cold and you went to an affected area within 14 days of when your symptoms began, once again, call Telehealth or contact your local public health unit and be sure to reveal your symptoms and travel history.

  • China (mainland)
