Flu Basics

Influenza (flu) is a contagious respiratory illness caused by influenza viruses. 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 for serious flu complications. The best way to prevent the flu is by getting vaccinated each year.  (Centers for Disease Control)

  • Flu season typically starts in the fall and peaks in January or February.
  • Getting a flu shot is your best protection against the flu.

If you have symptoms of flu and are worried about your illness contact your health care provider.  Certain people are at greater risk of serious flu-related complications (including young children, elderly persons, pregnant women and people with certain long-term medical conditions). (A full list of people at higher risk of flu related complications is available at People at High Risk of Developing Flu-Related Complications.)

Flu signs and symptoms usually include fever and respiratory symptoms, such as cough and runny nose, and possibly other symptoms, such as body aches, nausea, vomiting, or diarrhea.  For more helpful advice and a national perspective on preparations for the 2019-2020 flu season, visit the U.S. Centers for Disease Control and Prevention, as well as


How to Get a Flu Shot in Chicago

Chicago Department of Public Health holds no-cost flu clinics during the fall of each year. All of the 2019 CDPH flu clinics have now passed.

If you are unable to see your primary care provider for a flu shot, please refer to to find a pharmacy near you that is supplying flu vaccine this year. If you are a senior seeking high-dose flu vaccine, we encourage you to call ahead to the pharmacy to ensure high-dose flu vaccine availability.

Children 0-18 and uninsured adults who live within the city limits are also welcome to visit any of CDPH's five walk-in immunization clinics to receive a no-cost vaccine. Please check the clinics' schedules and arrive early, as they operate on a first-come, first-served basis.

CDPH also operates a mobile immunization CareVan in partnership with Blue Cross Blue Shield of IL that offers immunizations at different locations throughout the city. Please check the schedule to see when the CareVan will be at a location near you.
