Pennsylvania health officials confirmed on Tuesday that two unvaccinated Lancaster County residents have died from measles complications, the first measles deaths recorded in the commonwealth in 35 years and the first confirmed anywhere in the United States this year.
The Pennsylvania Department of Health announced the two deaths alongside Governor Josh Shapiro and Health Secretary Dr. Debra Bogen. Officials declined to release ages, sex, or dates of death, citing patient privacy. Both people lived in Lancaster County, the center of an outbreak that has pushed Pennsylvania to 393 confirmed cases across 28 counties this year.
For households inside the outbreak zone, the practical meaning is narrow but real. Until this week, Pennsylvania's measles story was a case-count story: 70 hospitalizations and no deaths. It is now a mortality story, and the shift arrives in the opening weeks of the school year, when exposure in classrooms, daycares, and waiting rooms peaks.
Inside the First Measles Deaths Pennsylvania Has Recorded in 35 Years
State officials confirmed only the essentials. Both people who died were Lancaster County residents; neither was vaccinated, and both deaths were classified as measles-associated, the standard term used when measles complications contribute to death.
Bogen declined to say whether either patient was pregnant or an infant, and the department said it will not release details that could identify the families. The ages, underlying conditions and specific complications are all unconfirmed. The Lancaster County coroner's office has not independently confirmed the deaths, which is not unusual, since not every death is referred to a coroner.
Officials framed the deaths within a statistical reality rather than as a surprise. The health department says measles deaths occur in one to three of every 1,000 reported cases, and that close to one in five people who contract measles are hospitalized. Pennsylvania has confirmed 393 cases this year, with 86 reported in the past week alone, and 70 people have been hospitalized.
Bogen said that because the disease was largely eliminated here for decades, "people are not familiar with this disease" and do not grasp how severe it can be. Shapiro, speaking at the Lancaster briefing, said of the two deaths, "We hope and pray that those deaths will be the last."
Lancaster County Carries the Outbreak, and Its Vaccination Rate Explains Much of It
Lancaster County has accounted for roughly half of Pennsylvania's cases since the outbreak began, and the county's immunization data explains why the virus has continued to spread. Measles vaccination coverage among Lancaster County children has fallen steadily, from 95.5 percent in 2017 to 87.6 percent in 2025, according to figures reported by NBC News.
That gap matters because measles requires unusually high coverage to stop. Officials cite a 95 percent threshold for community protection, since up to 9 in 10 susceptible people who are exposed become infected. Lancaster County is home to the country's largest Amish settlement, and the Association of Immunization Managers estimates that about a quarter of that population is vaccinated against measles, according to Time.
The national picture is moving the same way. The CDC has logged 2,777 confirmed cases this year, the highest annual total since 1991. The agency added 211 cases in its latest weekly update, more than double the prior week, with most of them in Pennsylvania and Ohio, according to the Center for Infectious Disease Research and Policy. About 7 percent of national cases have led to hospitalization, or 193 people as of August 20, and 94 percent of patients were unvaccinated or had unknown vaccination status. National kindergarten MMR coverage sits at 92.4 percent, down from 95.2 percent before the pandemic, per CDC measles data.
Families Near the Outbreak Face a Narrow Set of Decisions
The most useful action is also the least dramatic. Parents in Lancaster, Lebanon, Chester, Berks, York and surrounding counties can pull their children's immunization records and confirm two documented MMR doses. Two doses provide about 97 percent lifetime protection.
Adults who cannot locate records are not unusual. Many people counted as undocumented are vaccinated but missing paperwork, and a clinician can advise whether a repeat dose or a blood test makes sense. In counties with active transmission, the state has recommended an early MMR dose for infants aged 6 to 11 months rather than waiting for the standard 12 to 15 months. That early dose does not count toward the routine two-dose series.
Cost should not be the barrier. Pennsylvania residents can receive free vaccinations through state health centers in nearly every county, and pop-up clinics have been running in the Lancaster region since the outbreak began. Anyone with fever plus rash, cough, runny nose, or red eyes should call a provider before entering a waiting room so the office can prepare. Symptoms can start 7 to 21 days after exposure. Trouble breathing, severe dehydration, confusion or seizure activity warrants urgent evaluation. The state also runs a measles hotline at 877-PA-HEALTH.
MedicalDaily previously reported on Pennsylvania's school exclusion rule, which allows schools to keep unvaccinated students home for up to 21 days after a single confirmed exposure. That guidance has not changed.
Officials Have Withheld Key Details, and Several Questions Stay Open
Much about these deaths remains unconfirmed. The ages, whether either patient was a child or a pregnant adult, the complications involved, and whether either case traced to a known exposure event have all been withheld. Officials have not said whether additional deaths are under review.
It is also unclear whether the state total of 393 will hold, because counts are revised as laboratory confirmation catches up with reporting. The federal and state figures are current through different dates and should not be added or compared directly.
The department updates case numbers through its measles dashboard and the CDC posts national figures weekly. MedicalDaily will monitor both, as well as any changes to school exclusion guidance or infant vaccination recommendations.
The confirmed fact is narrow. Two unvaccinated people in one county have died, and the overwhelming majority of cases nationally have been in people who were unvaccinated or whose status was unknown. The households with the most at stake are those with infants too young for a first dose, immunocompromised members, or unvaccinated children where transmission is active. For nearly everyone else, the reasonable step is to check records rather than change routines.
Key Questions Answered
What exactly did Pennsylvania confirm? The state health department confirmed two measles-associated deaths. Both people were unvaccinated Lancaster County residents. These are the first measles deaths in Pennsylvania in 35 years and the first confirmed in the United States this year.
Were the people who died children? Officials have not said. The department declined to release ages, sex, or any other identifying detail, and specifically declined to answer whether either case involved a pregnant woman or an infant.
How many measles cases does Pennsylvania have? The state has confirmed 393 cases across 28 counties this year, with 86 reported in the most recent week. Roughly half are in Lancaster County, and 70 people have been hospitalized.
Is my vaccinated child at risk? The risk is low. Two documented MMR doses provide about 97 percent lifetime protection. Nationally, 94 percent of this year's patients were unvaccinated or had unknown vaccination status.
What should parents do first? Pull immunization records and confirm two documented MMR doses. Families in counties with active transmission should ask a clinician about an early dose for infants aged 6 to 11 months.
Where can uninsured families get the MMR vaccine? Pennsylvania offers free vaccination through state health centers in nearly every county, and county health departments and pop-up clinics in the Lancaster region have expanded access since the outbreak began.
When should someone seek urgent care? Fever with rash warrants a phone call to a provider before an in-person visit. Trouble breathing, severe dehydration, confusion, or seizure activity requires urgent medical evaluation.
