Pennsylvania’s flu surge strains hospitals as Lancaster County cases spike

Flu cases are surging across Pennsylvania, with hospitalisations expected to climb in Lancaster County and nearby areas. Health officials warn that the worst may not be over, as infection rates and emergency visits continue to rise. Over 50,000 confirmed cases have been recorded statewide since late September.

Lancaster County is facing a sharp increase in flu activity. As of January 3, the area reported 443.14 cases per 100,000 residents, ranking 15th among Pennsylvania’s 67 counties. While Allegheny and Philadelphia have higher total case numbers, their per-capita rates remain lower than Lancaster’s.

Hospitals are feeling the strain. WellSpan Health is treating more than 110 flu patients across its nine facilities—over twice last year’s figure at the same time. Penn State Health Lancaster Medical Center saw cases jump from just 4 in October to 160 in December, with 60 more recorded by January 3. The spike comes as this year’s flu vaccine does not fully match the dominant H3N2 subclade K, which emerged in August after vaccine strains were selected in February. Nationally, the flu has already caused 11 million illnesses, 120,000 hospitalisations, and 5,000 deaths, including nine children, as of December 27. Dr. John Goldman, UPMC’s epidemiologist in central Pennsylvania, predicts local flu rates, emergency visits, and hospitalisations will keep rising for another two to three weeks. Erie and Lehigh counties currently have higher case numbers and per-capita rates than Lancaster, but the region remains on high alert.

The flu season, which runs from autumn to spring, is hitting Pennsylvania hard. With infection rates still climbing, health systems are preparing for further pressure in the coming weeks. Officials continue to monitor hospital capacity and urge preventive measures as cases spread.
