Symptoms of COVID-19

View the list of commonly reported COVID-19 symptoms below.

 Symptoms of COVID-19
Symptoms of COVID-19 can vary from person to person. Symptoms may also vary in different age groups. Some of the more commonly reported symptoms include:
  • new or worsening cough
  • shortness of breath or difficulty breathing
  • temperature equal to or over 38°C
  • feeling feverish
  • chills
  • fatigue or weakness
  • muscle or body aches
  • new loss of smell or taste
  • headache
  • gastrointestinal symptoms (abdominal pain, diarrhea, vomiting)
  • feeling very unwell

Children have been more commonly reported to have abdominal symptoms, and skin changes or rashes. In severe cases, infection can lead to death.

Symptoms may take up to 14 days to appear after exposure to COVID-19.

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. This means it is extremely important to follow the proven preventative measures

COVID-19 Self-Assessment

Take the self-assessment questionnaire if you’re worried you were exposed to COVID-19 (novel coronavirus) or have symptoms.

COVID-19 Self-Assessment

Assessment Centres

The province has recently updated the guidelines for COVID-19 testing. Effective immediately, Assessment Centres will only be testing patients who:

  • have symptoms of COVID-19
  • were alerted to a potential exposure by the COVID-19 app or by Public Health
  • were in contact with someone who has COVID-19
  • were involved in a COVID-19 outbreak
  • are in an at-risk group as defined by provincial health officials

Assessment Centres will not be testing patients who do not meet the above criteria.

Think you might have COVID-19 or been exposed to someone with it? An appointment is required before attending and you are required to wear a mask or face covering. Please visit the assessment centres website links below for the most up-to-date information.
