Should I go see a doctor if my son is coughing a lot but has no other symptoms?

It is recommended to see a doctor if a cough has been present for more than 3 weeks and if there are symptoms such as fever, cough, shortness of breath, difficulty breathing, fatigue, sore throat, or muscle pain. If there has been recent travel outside of Canada, exposure in a targeted public place, close contact with a confirmed or probable case of COVID-19, or close contact with someone with an acute respiratory illness who has traveled, it is advised to call a specific phone number for further guidance. It is important to follow quarantine measures if experiencing flu-like symptoms and to avoid contact with others, especially older individuals, while practicing good hygiene. It's important not to panic as severe complications from the coronavirus are rare.
