When visiting with family and friends this week, the goal is to spread holiday cheer, not germs.
However, flu activity is starting to pick up across much of the country.
The Centers for Disease Control and Prevention says flu is now widespread in six states: Alabama, California, Delaware, Georgia, Massachusetts, and New York.
There are signs many areas of the southwest and mid-Atlantic aren’t far behind.
Doctors say the best way to protect yourself from the flu is by getting the flu shot.
You should also wash your hands often. Experts recommend a full 20 seconds of lathering up.
