Flu Cases Surge in Chicago, Hitting 3-Year High
Table of Contents
Chicago is currently experiencing a significant rise in flu cases, with hospitalizations and emergency room visits reaching levels not seen in three years. Health officials are urging residents to get vaccinated as the respiratory season progresses.
Current Flu Activity in Chicago
As of January 5, 2026, the Chicago Department of Public Health reports a positivity rate of just over 24% for influenza tests, indicating widespread activity [1]. Emergency room visits related to the flu are at “very high” levels, mirroring the peak seen in 2022.
The increase is particularly noticeable among children 17 years and younger, though all age groups are experiencing rising cases.
New Flu Variant Driving the surge
The current surge is attributed to a new variant of the influenza virus, known as “subclade K.” This variant has been linked to outbreaks globally [2], and its emergence is contributing to the increased number of infections.
National Flu Statistics
Nationwide, the flu is also causing significant illness. The Centers for Disease Control and Prevention (CDC) reports at least 81,000 hospitalizations and 3,100 deaths from the flu this season, including eight pediatric deaths [3].
Protecting Yourself and Others
Health officials emphasize that vaccination remains the most effective way to protect against severe illness from the flu. Free vaccinations are readily available at many pharmacies and city Immunization Clinics. A list of locations and hours can be found here.
Preventative Measures Beyond Vaccination
In addition to vaccination, healthcare professionals recommend practicing good hygiene to minimize the spread of the flu. Eileen Manojlovic,a family nurse practitioner with Rush University Medical Center,advises:
- Maintaining overall health through proper medication and a balanced diet.
- Drinking plenty of fluids.
- Staying home when experiencing a fever.
- covering coughs and washing hands frequently.
Manojlovic also notes that stress and lack of sleep can weaken the immune system, increasing susceptibility to the virus. Rush University Medical Center offers vaccinations at its urgent care locations at 1625 N. Harlem ave. and 539 N. Dearborn St.
Other Respiratory Viruses
While the flu is currently the dominant respiratory illness, the Chicago department of Public Health reports that Respiratory Syncytial Virus (RSV) activity is “moderate,” and COVID-19 activity “remains low.”
