Illinois Residents Urged to Act as Whooping Cough Cases Hit 20-Year High

As colder weather settles across Illinois, the Illinois Department of Public Health (IDPH) is urging residents to prepare for respiratory virus season.

While flu, COVID-19, and RSV vaccines are strongly recommended, public health officials are also highlighting a sharp rise in whooping cough (pertussis) cases, which have reached their highest level since 2012, according to an IDPH press release.

Whooping Cough Surge Alarms Officials

In October, Illinois reported 408 whooping cough cases—the largest monthly total in 20 years—more than doubling last year’s figure for the same period.

Preliminary 2024 data shows over 1,900 confirmed or probable cases statewide, reflecting a national trend of increased pertussis activity post-pandemic.

"The post-pandemic rise in pertussis cases is a cause for concern," said IDPH Director Dr. Sameer Vohra. The agency has issued health alerts to local providers and schools, emphasizing the importance of timely vaccinations and prompt reporting of cases.

Prepare for Respiratory Virus Season

Dr. Vohra also reminded Illinoisans to get updated vaccines for flu, COVID-19, and RSV ahead of the holiday season. Vaccines take about two weeks to become fully effective and are especially critical for individuals over 65, those with chronic conditions, and the immunocompromised.

The new COVID-19 and flu vaccines are recommended for everyone over 6 months old, while the RSV vaccine targets adults 75 and older, pregnant women, and newborns through specific programs.

Where to Find Vaccines and Resources

Vaccines are widely available at pharmacies, community clinics, and health departments. Residents can find local providers at www.vaccines.gov.

Free COVID-19 tests are available through covidtests.gov, and IDPH operates the Vaccines for Children Program to ensure access for uninsured youth. Adults without insurance can contact free or charitable clinics or local health departments.

Quick Action Reduces Risk

Health officials emphasize staying home when sick and seeking treatment quickly if respiratory symptoms develop.

COVID-19 antivirals and flu treatments are most effective when started early and are crucial for high-risk individuals. Testing locations for COVID-19 can be found using the federal ICATT locator.
