Do you have the cold or flu?

If you're under the weather, and wondering if it's the cold or flu, there usually a way to tell.

With the flu, symptoms often appear suddenly, without warning. You could literally feel fine one hour and the next be lying in bed with terrible aches and pains.

A lot of people say it's like being hit by a truck. You don't feel like doing anything, you just want to lie down and go to sleep.

Doctors say you'll usually get a very high fever with the flu and a dry cough.

For kids, vomiting and diarrhea are common symptoms.

Doctors say if you have a cold, symptoms will appear gradually. You'll have a mild fever and a runny or stuffy nose.

Typically colds will not cause serious complications.

But if you have the flu, there's always the risk of something much more serious like pneumonia or bacterial infections.
