COVID-19 and the flu share many symptoms, including fever or chills, cough, fatigue, muscle or body aches, headache, sore throat, and congestion or runny nose. Both can also cause nausea, vomiting, and diarrhea, though these are more common in children with the flu. A key distinction is that COVID-19 frequently causes a loss of taste or smell, which is less common with the flu. Additionally, flu symptoms typically appear more suddenly, while COVID-19 symptoms may develop more gradually.
