Signs and symptoms of COVID-19 may appear two to 14 days after exposure and can include fever, cough, shortness of breath or difficulty breathing. Other symptoms can include tiredness, aches, runny nose and sore throat.
The severity of COVID-19 symptoms can range from very mild to severe. Some people have no symptoms. People who are older or have existing chronic medical conditions, such as heart or lung disease or diabetes, may be at higher risk of serious illness. This is similar to what is seen with other respiratory illnesses, such as influenza.
