Sickness spreads in many ways. You can breathe in germs when someone talks, coughs, or sneezes. You get some diseases, like chickenpox or pinkeye, if you touch a person who has it. And you can catch others, like hepatitis B, by having sex with an infected person or by coming in contact with their blood.
To prevent flu -- or any illness -- you've got to stick with a healthy lifestyle.
"I really believe your immune system takes care of a lot of things," says Erica Brownfield, MD, a professor of internal medicine at Emory University School of Medicine in Atlanta. "Even if you've been exposed to the flu, you don't have to get it."

Germs are everywhere. Follow these five easy steps to help keep your family clear from catchy infections.

Then they should get a diphtheria/tetanus, or Td, booster every 10 years. People over 60 should get a shot to prevent shingles. People 65 and over need to get two pneumonia shots. And most everyone over 6 months old should get a yearly flu vaccine. Adults may also need any vaccinations that they didn't get as children.
Remember, more shots means fewer chances for disease to spread.
Wash Your Hands
The CDC calls hand washing a “do-it-yourself vaccine.” It’s one of the easiest things you can do to stop germs in their tracks. Follow these steps to make sure:
Wet your hands with clean, running water (warm or cold).
Use soap. Rub your hands together for 20 seconds - about as long as it takes to sing “Happy Birthday” twice.
Dry your hands with a clean towel or let them air dry.
Don’t have soap and water? Use a hand sanitizer with at least 60% alcohol.
