Practice good hand hygiene by washing your hands with soap and water, especially after coughing or sneezing. Alcohol-based hand cleaners also are effective.

Cover your mouth and nose with a tissue when you cough or sneeze. If you don't have a tissue, cough or sneeze into your elbow or shoulder, not into your hands. Avoid touching your eyes, nose, or mouth; germs are spread this way.

Know the signs and symptoms of the flu. A fever is a temperature taken with a thermometer that is equal to or greater than 100 degrees Fahrenheit or 38 degrees Celsius. Look for possible signs of fever: if the person feels very warm, has a flushed appearance, or is sweating or shivering.

Stay home if you have the flu or flu-like illness for at least 24 hours after you no longer have a fever (100 degrees Fahrenheit or 38 degrees Celsius) or signs of a fever (have chills, feel very warm, have a flushed appearance, or are sweating). Don't go to class or work.

Talk with your health care providers about whether you should be vaccinated for seasonal flu.
