You can take some other simple steps to dodge it. Try not to touch your eyes, nose, and mouth, because germs are spread that way. Wear a face mask. Wash your hands often with soap and water. Or use an alcohol-based hand sanitizer when soap and water aren't around.
If you get sick, you can keep other people from getting the flu by staying away from them. Cover your mouth and nose when you cough and sneeze, too. If you don't have a tissue handy, the inside crook of your elbow is a great place to do it, so you don't get germs on your hands.
