Learn about COVID-19 symptoms and what to do if you experience symptoms. If you are a close contact of someone who has COVID-19, you should closely monitor for symptoms and get tested if symptoms develop – even if you have already been tested. If you are not a close contact, you should use the COVID-19 Self-Assessment Tool to determine if you should get tested.

COVID-19 causes a range of symptoms that vary from person-to-person. Some people may experience mild or no physical symptoms. Symptoms can take up to 14 days after exposure to COVID-19 to appear, and include new or worsening:

  • Fever
  • Cough
  • Difficulty breathing
  • Sore throat
  • Runny nose
  • Loss of taste or smell
  • Nausea, vomiting, diarrhea
  • Difficulty swallowing
  • If you are having difficulty breathing, call 911.

Disease symptoms may be different, depending on age. Children and older adults with COVID-19, may also have non-specific symptoms (also available in French), such as: disorientation, confusion, sleeping more than usual or muscle aches, dizziness, weakness or falls, chills, headaches.

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.

For others, there is a higher risk for severe illness, including people over the age of 60, and those with weakened immunity or underlying health conditions.

If you are a low-risk (non-close) contact, you may have been instructed by Toronto Public Health or a health care provider to self-monitor for symptoms of COVID-19. Follow Public Health Ontario’s instructions on how to self-monitor.

If you develop any symptoms of COVID-19, you must stay home and self-isolate until you test negative for COVID-19 or a healthcare provider has diagnosed a condition that is not related to COVID-19. Your household members must also stay home until you test negative or receive an alternative diagnosis. If you choose not to get tested, you must self-isolate for 10 days from when your symptoms started. Your household members must self-isolate for 14 days from their last contact with you, after you began having symptoms (unless they are able to effectively self-isolate away from you).

Follow Public Health Ontario’s instructions on how to self-isolate if you develop symptoms. Instructions on how to self-isolate are also available in: French | Arabic | Bengali | Simplified Chinese | Traditional Chinese | Eastern Ojibwe | Farsi | German | Greek | Gujarati | Hindi | Italian | Japanese | Korean | Mohawk | Oji-Cree | Polish | Portuguese | Punjabi | Romanian | Russian | Somali | Spanish | Swampy Cree | Tagalog | Tamil | Ukrainian | Urdu | Vietnamese

Anyone with symptoms should arrange to get tested at a community Assessment Centre.  Continue to self-isolate until you receive a negative test result, and have been feeling better for at least 24 hours.
