Flu Information

Influenza (the flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness. Serious complications of flu infection can result in hospitalization or death. Some people, such as elderly, young children, and people with certain health conditions, are at higher risk for serious flu complications.

The best way to prevent the flu is by getting immunized each year. The upcoming season's flu vaccine will protect against the influenza viruses that research indicates will be most common during the season.


To request a pop-up Flu vaccine clinic at a community event, please fill out an interest form here.  In efforts of accommodating your request, please submit the interest form at least 7 business days prior to the event date.

Flu can be very serious for people of all ages, even for healthy young adults, which is why it is recommended that everyone older than 6 months of age receive a yearly flu immunization.

Flu immunizations can be found at a number of locations:

  • Your healthcare provider. Make an appointment with your primary care provider each flu season to get your seasonal flu vaccine.
  • HealthMap Vaccine Finder - Input your zip code to find immunizations near you.
