How does the flu spread?

The flu virus is mainly spread by droplets when someone with the flu coughs, sneezes or talks. These droplets can then land in the mouths or noses of people who are nearby. Also a person might get the flu by touching a surface or object that has the flu virus on it and then touching their own mouth, eyes or nose.

What are signs and symptoms of the flu?

  • Fever or feeling feverish/chills (Not everyone with the flu will have a fever)
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Muscle or body aches
  • Headaches
  • Fatigue
  • Some people may have vomiting and diarrhea, though this is more common in children than adults

How long are you contagious with the flu?

You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Most healthy adults may be able to infect others beginning one day before symptoms develop and up to 5 to 7 days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for an even longer time.

What else can I do to prevent the flu?

  • Cover your nose and mouth with your sleeve or a tissue when you cough or sneeze.
  • Wash your hands often with soap and water, especially after you cough or sneeze. If you are not near water you can use an alcohol based sanitizer.
  • Stay away as much as you can from people who are sick.
  • If you get the flu, stay home from work or school for at least 24 hours after the fever has ended. If you are sick, don’t go near other people to avoid infecting them.
  • Try not to touch your eyes, nose or mouth. Germs often spread this way.
