The number of new hospitalizations per 100,000 population for Cook County has decreased from 2.4 to 2.0.
The test positivity for SARS-CoV-2 has decreased from 3.5% to 2.8%.

Influenza:

Influenza activity remains high with the majority of specimens testing positive for influenza B.
Three influenza-associated ICU hospitalizations were reported for the current surveillance week. Since October 1, 2023, 280 influenza-associated ICU hospitalizations have been reported.
328 of 4,943 (6.6%) reported specimens tested for influenza were positive. Since October 1, 2023, 9,994 of 144,589 (6.9%) reported specimens tested for influenza were positive.
The proportion of emergency department visits for influenza-like illness (ILI) is above local thresholds and the proportion of outpatient visits for ILI is below local thresholds.
Vaccination is the best way to protect against influenza infection and all Chicagoans six months and older are encouraged to get vaccinated. Influenza and COVID-19 vaccines can be given at the same visit if the timing coincides.
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.
