The single best way to prevent the flu is to get vaccinated each fall, and to practice good health habits. Avoid close contact with people who are sick. When you are sick, keep your distance from others to protect them from getting sick too. Also, cover our mouth and nose with a tissue when coughing or sneezing. It may prevent those around you from getting sick.
Additionally, stay home when you are sick. If possible, stay home from work, school, and errands when you are sick. You will help prevent others from catching your illness. Avoid touching your eyes, nose, or mouth. Germs are often spread when a person touches something that is contaminated with germs and then touches his or her eyes, nose, or mouth.
Also, washing your hands often will help to prevent the spread of germs. Wash all surfaces, including the backs of hands, wrists, between fingers, and under fingernails for a minimum of 20 seconds with warm soapy running water. Rinse well and dry hands with a clean towel, paper towel, or air dyer.
