Pennsylvania Reports First Measles Deaths in 35 Years Amid Rising U.S. Outbreak

Pennsylvania has recorded its first measles deaths in 35 years during a state outbreak that has grown to 393 cases, according to state health officials and reporting by outlets including CNN and NBC News. The fatalities and infections reflect a broader national surge in measles cases across the United States driven by declining vaccination rates.

According to the Pennsylvania Department of Health, the two deaths occurred in Lancaster County, which has emerged as the epicenter of the state’s outbreak. State health officials reported that the victims were unvaccinated individuals living in the county, where confirmed infections have driven the state total across 28 counties.

Outbreak Scale and Hospitalizations in Pennsylvania

The outbreak in Pennsylvania represents the state’s most severe spread of the virus in over three decades. State figures show that 70 people have required hospitalization for complications related to the virus.

Public health authorities emphasize that measles remains entirely preventable through immunization, though the disease can lead to severe medical conditions such as pneumonia, brain inflammation, hearing loss, intellectual disability, and death. According to public health data cited by CNN, fatalities occur in between one and three out of every 1,000 measles cases.

Declining Vaccination Coverage and National Trends

The resurgence of measles in Pennsylvania coincides with a measurable drop in uptake for the measles, mumps, and rubella (MMR) vaccine. NBC News reported that vaccination coverage in Lancaster County fell from 95.5% in 2017 to 87.6% in 2025.

Pennsylvania Health Secretary Dr. Debra Bogen noted that the multi-decade absence of measles fatalities caused many residents to lose awareness of the disease’s severity.

Due to that the measles was in large part eliminated in the Commonwealth for more than three decades, the people are not familiar with this disease and do not understand of the full possible gravity of the picture.

The vast majority of individuals infected nationwide were not vaccinated. National kindergarten exemption rates rose to 4.2% in 2026, up from 3.6% the prior year, affecting approximately 155,000 children.

Public Health Response and Expert Commentary

Federal health tracking indicates that the United States is experiencing its second year of record-high measles counts, threatening the nation’s elimination status originally achieved in 2000.

Medical specialists and pediatricians have reiterated calls for families to maintain immunization schedules. Dr. Paul Offit, an infectious disease specialist and director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, emphasized the preventable nature of the current fatalities in remarks covered by CNN, stating that these deaths are totally preventable.
