How else can I prevent the spread of flu?

  • Wash your own and your child’s hands often with soap and warm water. Children should sing their ABCs twice in a row while washing their hands to ensure the proper length of time. Use alcohol-based hand cleansers when soap and water are not available. Learn more about handwashing.
  • The social distancing and masking efforts to reduce the spread of COVID-19 also help reduce spread of the flu. Wear a mask when in public and when around people you don’t live with.
  • Avoid people who are sick.
  • People with the flu should stay home from work or school. They should stay home while they are sick and for at least one day after they no longer have a fever, without the use of fever-reducing medicines. Learn more about flu symptoms and care advice.
  • Cover noses and mouths when coughing or sneezing: use tissue or the crook of your elbow when you cough or sneeze and throw the tissue away in a covered trash bin.
  • Avoid touching your eyes, nose and mouth with unwashed hands. Remind children to keep their hands away from their face to avoid touching their eyes, nose or mouth.
  • Clean surfaces often, including toys, doorknobs, phone receivers, keyboards and tables.
  • Avoid sharing personal items such as forks, spoons, toothbrushes and towels.
  • The single best way to prevent the flu is to get the vaccine every flu season.
