The flu virus spreads easily - traveling as far as 6 feet - and lingering in the air.
So what are the top three ways to catch the flu?
- The Center for Disease Control says, being near someone who is sick, who sneezes, coughs or talks, releasing germs.
- Drinking from the same cup as an ill person, or sharing utensils.
- Touching a germ-infected surface and then touching your eyes or mouth.
Also, you can pass the virus to someone before you even know you're sick.
But, disease control experts say, it's not too late to do something to protect yourself and get that flu shot. Shots are recommended for everyone over 6 months old.
