Flu information and resources

Influenza (flu) is a serious contagious respiratory illness caused by influenza viruses. Flu activity is widespread in California and most of the United States. It can cause mild to severe illness. Serious outcomes of flu infection can result in hospitalization or death. Some people, such as older people, young children, and people with certain health conditions, are at high risk of serious flu complications.

You can take some basic steps to protect yourself and family from getting flu and other respiratory infections.

  1. Get a flu vaccine. Everyone 6 months of age and older should get a flu vaccine, if possible. A yearly flu vaccine is the first and most important step in protecting against the flu.
  2. Take everyday actions to stop the spread of germs. Try to avoid close contact with sick people, and if you become sick, limit your contact with others. When possible, stay home for at least 24 hours after your fever is gone. Cover your nose and mouth with a tissue when you cough or sneeze, and wash your hands often with soap and water. If soap and water are not available, use an alcohol-based hand rub.
  3. Take flu antiviral drugs if your doctor prescribes them. If you get the flu, prescription medicine called antiviral drugs can be used to treat flu illness. Antiviral drugs can make illness milder and shorten the time you are sick. They may also prevent serious flu complications. Learn more about how you can fight flu this season.
