COLD OR THE FLU?

How to Tell the Difference Between a Cold and the Flu

The cold and flu are both respiratory illnesses, but they are caused by different types of viruses. Flu symptoms usually come on quickly (within 3-6 hours) and consist of a fever, body aches, dry cough, and extreme tiredness. Cold symptoms are less severe and people experience a stuffy nose, productive cough, slight tiredness, and limited body aches.
