565 of 6,313 (8.9%) reported specimens tested for influenza were positive. Since October 1, 2023, 5,483 of 84,789 (6.5%) reported specimens tested for influenza were positive.

Chicagoans should ask their healthcare provider or pharmacist about vaccine availability. For those without a healthcare provider or whose healthcare providers do not have the influenza vaccine, a schedule of City of Chicago influenza vaccination clinics is available on the city website and by calling 311.
The Illinois Department of Public Health has issued Influenza Testing and Reporting Guidance for the 2023-2024 season. Visit the CDPH HAN website for more information on how to report.
