The flu and the common cold have similar symptoms. It can be difficult to tell the difference between them. Your health care provider can give you a test within the first few days of your illness to determine whether or not you have the flu.
In general, the flu is worse than the common cold. Symptoms such as fever, body aches, tiredness, and cough are more common and intense with the flu. People with colds are more likely to have a runny or stuffy nose.
