Get vaccinated! The single best way to prevent the flu is to get a flu vaccine each season. The seasonal flu vaccine protects against the influenza viruses that research indicates will be most common during the upcoming season.
Avoid close contact with people who are sick. When you are sick, keep your distance from others to protect them from getting sick too.
Stay home when you are sick. If possible, stay home from work, school, and errands when you are sick.
Cover your mouth and nose with a tissue when sneezing or coughing. If you don’t have a tissue available, cover your mouth with the inside of your elbow, not your hand.
Clean your hands. Wash them often and thoroughly.
Avoid touching your eyes, nose, or mouth. Most experts believe that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby. Less often, a person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes, or nose.
Clean and disinfect surfaces or objects.
