What happened
A 39-year-old unvaccinated woman in Franklin County died on October 10, 2026, from complications of measles, becoming Pennsylvania’s sixth measles-associated death this year. The Franklin County Coroner’s office confirmed the death met the state’s criteria for a measles-associated death, citing underlying health conditions and a recent positive measles test. All six deaths involved unvaccinated individuals, including two infants too young to receive the vaccine.Who is affected
The outbreak has spread across 41 of Pennsylvania’s 67 counties, with Lancaster County reporting the highest number of cases. Adults aged 18 to 24 make up the largest affected age group, contrary to the national trend where children and teenagers are most commonly infected. Unvaccinated individuals account for more than 99 percent of confirmed cases. See the table above for verified figures.What to do next
Pennsylvania health officials urge unvaccinated residents to receive the measles, mumps, and rubella (MMR) vaccine, which is available at no cost through pop-up clinics. Two doses provide 97 percent protection, and the state has administered over 5,900 doses at these clinics since the outbreak began. Residents with unknown vaccination status or only one dose should consult a healthcare provider.What we know and don’t know
We know the outbreak began in late April 2026 and has since spread rapidly, with cases rising by more than 100 per week. However, we do not yet know the full extent of undiagnosed cases, as many mild infections go unreported. The Centers for Disease Control and Prevention (CDC) has not yet included all Pennsylvania deaths in its national tally due to differing reporting criteria.Timeline of Pennsylvania’s sixth measles-linked death
- Late April 2026: Outbreak begins in Pennsylvania.
- August 2026: First two measles-associated deaths reported in Lancaster County (both infants).
- September 30, 2026: Fifth death reported in Lancaster County.
- October 10, 2026: Sixth death confirmed in Franklin County.
- October 13, 2026: State reports 1,136 confirmed cases and 219 hospitalizations.
Why it matters
The outbreak has raised concerns about declining vaccination rates and the potential loss of the U.S.’s measles elimination status, which requires no continuous transmission for 12 months. Experts warn that measles can cause severe complications, including pneumonia and brain swelling, particularly in unvaccinated individuals.How the outbreak compares to national trends
Pennsylvania accounts for more than a quarter of the 4,080 national measles cases reported in 2026, the highest total since 1991. Nationally, 95 percent of cases occur in unvaccinated people or those with unknown vaccination status. The CDC has only included two of Pennsylvania’s deaths in its tally, citing reporting discrepancies.How vaccination rates are changing
Pennsylvania providers typically administer 25,000 MMR doses monthly, but over 56,000 doses were given in September 2026—more than double the usual volume. This surge reflects increased demand amid the outbreak, though vaccination rates remain below the 95 percent threshold needed for herd immunity.Frequently asked questions
How does Pennsylvania define a measles-associated death?
The state defines a measles-associated death as one occurring within 30 days of symptom onset in a person with clinical evidence of measles, a positive laboratory test, and no unrelated cause of death. The Franklin County case was the first such death in the county in many years.
Why are some deaths not included in the CDC’s national tally?
The CDC only counts deaths when measles is listed as the underlying cause on official death records, a stricter criterion than Pennsylvania’s definition. This has led to discrepancies, with Pennsylvania reporting six deaths while the CDC includes only two.
How effective is the MMR vaccine?
Two doses of the MMR vaccine are 97 percent effective at preventing measles. The vaccine is available at no cost through state pop-up clinics, and health officials urge unvaccinated residents to get protected.
What are the symptoms of measles?
Complications can include pneumonia, encephalitis, and death, particularly in unvaccinated individuals.
How can I protect myself and my family?
Ensure you and your family are vaccinated with two doses of the MMR vaccine. Infants under six months are too young for vaccination and rely on community immunity. Avoid close contact with unvaccinated individuals during outbreaks.
