Is It a Cold or the Flu?

The cold and flu are both respiratory illnesses, but they are caused by different types of viruses with different symptoms. Use this chart to learn the difference between the two.

If you or a family member are experiencing symptoms that sound more like the flu than a cold call your doctor right away.

There are prescription medicines that can actually help prevent you from getting the flu – or shorten the duration if you already have it. But you must start treatment within 48 hours of first symptoms.
