The common cold and the flu may seem very similar at first. They are indeed both respiratory illnesses and can cause similar symptoms. However, different viruses cause these two conditions, and your symptoms will gradually help you differentiate between the two.
Both a cold and the flu share a few common symptoms. People with either illness often experience:
- a runny or stuffy nose
- sneezing
- body aches
- general fatigue.
As a rule, flu symptoms are more severe than cold symptoms.
Another distinct difference between the two is how serious they are. Colds rarely cause additional health conditions or problems. The flu, however, can lead to sinus and ear infections, pneumonia, and sepsis.
To determine whether your symptoms are from a cold or from the flu, you need to see your doctor. Your doctor will run tests that can help determine what’s behind your symptoms.
