The best way to prevent the flu is by getting vaccinated each year.

CDC recommends that everyone 6 months of age and older get their yearly flu vaccine now. Flu vaccine is especially important for infants, young children, pregnant women, adults over 65, and for those with chronic medical conditions.

Flu virus is mainly spread through droplets from coughs and sneezes. Remember these important everyday steps to help stop the spread of germs:

  • cover your cough with a sleeve or tissue
  • wash your hands often
  • stay home if you are sick

More Information About Seasonal Influenza (Flu)

CDC recommends everyone 6 months of age and older get their yearly flu vaccine now. While everyone should get a flu vaccine each flu season, it's especially important certain people get vaccinated either because they are at high risk of having serious flu-related complications or because they live with or care for people at high risk for developing flu-related complications. These groups include:

  1. Pregnant women (including women up to two weeks postpartum)
  2. Children younger than 5 years—especially children younger than 2 years old
  3. People 65 years of age and older
  4. People who live in nursing homes and other long-term care facilities
  5. American Indians and Alaskan Natives seem to be at a higher risk of flu complications
  6. People who have certain chronic medical conditions (more information here)

The CDC recommends use of the flu shot (inactivated influenza vaccine). The nasal spray flu vaccine (live attenuated influenza virus) should not be used during 2016-2017.
