How to tell a cold from the flu

[September 30, 2009]  (AP)  The common cold and flu -- both the seasonal and the new swine flu -- are caused by different viruses but can have some similar symptoms, making them tough to tell apart. In general, the flu is worse and symptoms are more intense.

COLDS: Usual symptoms include stuffy or runny nose, sore throat and sneezing. Coughs are hacking and productive. It's unusual to have fever, chills, headaches and body aches, or if present, those symptoms will be mild.

FLU: Fever is usually present, along with chills, headache and moderate-to-severe body aches and tiredness. Symptoms can come on rapidly, within three to six hours. Coughs are dry and unproductive, and sore throats are less common.
