The flu is serious.

The flu can hit you fast and leave you with debilitating symptoms that last for more than a week. And it’s not just you. The CDC estimates that each year, up to 45 million people will be affected by the flu.* It can also lead to serious complications.

Look out for three common flu symptoms.

You don’t have to have all of the symptoms above to have the flu. If you’re experiencing any symptoms, don’t wait for things to get worse—see your doctor when they first appear.
