HARRISBURG — Health officials are warning of a significant spike in respiratory illness across the Commonwealth as the 2025-2026 flu season enters its most intense phase.
The Pennsylvania Department of Health released updated data through last Saturday, revealing that lab-confirmed influenza cases have now climbed to 35,055 since the season began on September 28.
Rising fatalities and hospital strain
The surge in cases has unfortunately turned fatal for nearly two dozen residents. According to data from the National Center for Health Statistics, 22 flu-related deaths have been confirmed in Pennsylvania so far this season.
Perhaps the most alarming metric for healthcare providers is the strain on local hospitals. Over the past week, the percentage of emergency department visits resulting in an influenza diagnosis was classified as “very high” statewide. This trend is not limited to any specific demographic, as health officials noted high levels of infection across all age groups.
Flu vs. RSV: A tale of two viruses
While the flu is dominating the current health landscape, Pennsylvania is also tracking Respiratory Syncytial Virus (RSV). However, the data shows a stark difference in how the two viruses are currently impacting the population:

Prevention and advice
Health experts continue to urge residents to take standard precautions as holiday gatherings continue:
Vaccination: It is not too late to receive a flu shot, which can significantly reduce the severity of the illness.
Hygiene: Frequent handwashing and staying home when symptomatic remain the best defenses against community spread.
When to seek care: While ER visits are high, officials suggest contacting primary care physicians for mild symptoms to help alleviate the burden on emergency rooms.
