Springfield, IL – The Illinois Department of Public Health (IDPH) is reporting a significant increase in flu activity across the state, with officials confirming the first pediatric influenza death of the 2025–26 season. Health authorities are urging residents to take precautions as influenza cases reach the highest level of severity on the CDC’s scale.
Illinois is experiencing very high influenza activity, the most severe of five respiratory illness levels defined by the U.S. Centers for Disease Control and Prevention (CDC). This uptick comes as COVID-19 cases also rise to moderate levels statewide, compounding public health concerns during the winter season.
“The combination of high flu activity and moderate COVID-19 levels highlights the need for continued vigilance,” said an IDPH spokesperson.
Pediatric Impact
The first child influenza death for the current season was recently reported by IDPH. During the 2024–25 flu season, Illinois recorded 12 pediatric deaths from influenza, emphasizing the potential severity of flu in children.
“We are saddened by this loss and remind parents that vaccination and early treatment remain key tools in protecting children from influenza,” the spokesperson said.
Flu Activity and Public Health Response
IDPH monitors flu activity weekly through data reported from hospitals, clinics, and laboratories statewide. Officials confirm that influenza cases are spreading rapidly, with high rates of outpatient visits for flu-like illness.
Key factors contributing to the surge include:
- Seasonal influenza virus circulation
- Lower-than-expected vaccination coverage in some populations
- Co-circulation with COVID-19, RSV, and other respiratory illnesses
Residents are encouraged to:
- Get vaccinated against influenza and COVID-19
- Practice good hygiene, including frequent handwashing
- Stay home when sick to prevent spreading illness to others
- Seek medical attention promptly if flu symptoms worsen
COVID-19 and Other Respiratory Viruses
Alongside influenza, IDPH reports that COVID-19 infection rates have risen to moderate levels. While not at pandemic peaks, this increase in respiratory illness emphasizes the importance of monitoring symptoms and testing as needed.
“Even moderate COVID-19 activity can strain healthcare systems if combined with high flu activity,” IDPH noted.
Other respiratory viruses, including RSV and common cold viruses, are also circulating, which may contribute to increased hospital visits and clinical complications.
Recommendations for Residents
Health officials recommend that everyone over six months of age receive the influenza vaccine, even if already vaccinated earlier in the season. Children, the elderly, and people with underlying health conditions are particularly vulnerable and should seek vaccination immediately.
IDPH also reminds residents that antiviral medications can reduce the severity of influenza if administered early. Individuals experiencing high fever, persistent cough, or breathing difficulties should contact a healthcare provider without delay.
Conclusion
Illinois is confronting a serious surge in flu activity alongside moderate COVID-19 transmission. With the first child flu death of the season now reported, public health officials stress vaccination, hygiene, and early treatment as critical measures to protect residents statewide.
