COVID-19 and the flu (influenza) are both respiratory illnesses caused by different viruses, and while they share some symptoms, there are also some important differences:
Common symptoms of COVID-19 include:
- Fever or chills
- Cough
- Shortness of breath or difficulty breathing
- Fatigue
- Muscle or body aches
- Headache
- Loss of taste or smell
- Sore throat
- Congestion or runny nose
- Nausea or vomiting
- Diarrhea
Common symptoms of the flu include:
- Fever or feeling feverish/chills
- Cough
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Headaches
- Fatigue (tiredness)
- Some people may have vomiting and diarrhea, though this is more common in children than adults.
While both COVID-19 and the flu can cause serious illness, COVID-19 appears to be more contagious and can result in more severe illness and complications, particularly among older adults and those with underlying health conditions. It is important to seek medical attention if you experience any of these symptoms, particularly if you have been in close contact with someone who has COVID-19 or if you are at higher risk for severe illness.
