Pennsylvania confirmed its sixth measles-associated death in 2026, with the state reporting over 1,100 cases and 198 hospitalizations as the outbreak worsens. The death of a 39-year-old Franklin County woman, who had underlying conditions, marks the latest in a series of fatalities linked to the largest measles crisis in decades.
Updated October 20, 2026
The Pennsylvania Department of Health confirmed the state’s sixth measles-related death on October 12, 2026, as the outbreak continues to strain healthcare systems and public health infrastructure. The victim, a 39-year-old woman from Franklin County, had several underlying health conditions and a prior measles diagnosis, according to the county coroner. Her primary cause of death was listed as a probable acute cardiac event due to complications from measles, though the exact connection remains under review.
Outbreak Spreads Across 41 Counties
The outbreak has also affected pregnant women and newborns. Doctors warn that measles can lead to severe complications during pregnancy, including preterm labor and congenital measles, a rare but life-threatening condition. Vaccinated pregnant people pass antibodies to their infants, offering critical protection,
said Dr. Sharee Livingston, an OBGYN in Lancaster County.

Pennsylvania’s measles outbreak has reached historic levels, with over 1,100 confirmed cases as of October 12, 2026, and 198 hospitalizations. The state’s health department reported that 99% of cases involve unvaccinated individuals, with only four cases in vaccinated people. The outbreak has spread across 41 counties, with the largest numbers of cases occurring in people aged 25 to 49, a demographic less commonly affected in past outbreaks.
The virus’s rapid spread has been exacerbated by low vaccination rates in certain communities. In Pennsylvania, more than half of counties have MMR vaccination rates below 95%, the threshold needed to prevent outbreaks. Experts like Dr. Peter Chin-Hong, an infectious diseases specialist, note that the low vaccination rates, combined with the virus’s extreme contagiousness, have created a perfect storm for transmission. It’s the most contagious virus we know,
Chin-Hong said, emphasizing that measles can linger in the air for hours after an infected person has left a room.
Controversies Over Death Toll and Federal Response
A dispute has emerged between Pennsylvania and federal health officials over the number of measles-related deaths. Pennsylvania has reported five deaths since late August, while the CDC has only recognized two. The state’s definition of a measles-associated death
includes cases where the virus is linked to symptoms within 30 days of infection, a broader standard than the CDC’s. This discrepancy has led to tensions, with Pennsylvania threatening to withdraw support for federal outbreak assistance unless the deaths are acknowledged.
The conflict highlights deeper political and public health divisions. Health and Human Services Secretary Robert F. Kennedy Jr. has faced criticism for undermining vaccine infrastructure and spreading misinformation about vaccines, according to a report in the Pennsylvania Capital-Star. Meanwhile, the CDC’s decision to count deaths only when measles is listed as the underlying cause of death has been called extraordinary political interference
by experts.
The federal government’s approach has also drawn scrutiny. In September 2026, the CDC reported 4,080 cases nationally, the highest number in decades, with five deaths in Pennsylvania. However, the agency has not yet confirmed the state’s sixth death, pending further review. The story’s not been fully told yet,
said Dr. Chin-Hong, noting that many cases may go unreported due to under-testing.

Franklin County’s coroner noted the death matched Pennsylvania’s reporting standard for deaths related to measles.
Previous reported deaths include two infants from Amish families in Lancaster County, an 18-year-old in Mifflin County, and a 40-year-old woman. The five measles-associated deaths— the first in the state in 35 years—have drawn national attention.
Vaccination Gaps Widen in Key Areas
Health officials are urging residents to get vaccinated, particularly in areas with low immunization rates.
Efforts to boost vaccination rates have included emergency doses in high-risk areas. In Lancaster County, for example, health officials reported giving more than three times as many MMR doses in 2026 as in 2025. However, disparities persist: in Lancaster County, 88% of pupils were vaccinated against measles last school year, against 97% across Pennsylvania. Closing local coverage gaps is what matters most,
said The Conversation, citing the UK’s successful recovery of its measles elimination status after a similar crisis.
However, the current outbreak is the largest since 1991, when the nation recorded 9,643 cases. US officials recorded 27,786 infections in 1990 and 17,840 cases in 1989. The 1989-1991 epidemic was blamed on budget cuts to vaccination programs and national recommendations calling for children to receive just one dose of measles vaccine.
Experts have linked declining vaccination rates in part to growing vaccine skepticism. The US has recorded 3,887 cases of measles so far this year, the highest annual total since 1991. Nationwide, the CDC data show 4,080 cases nationally and two deaths, with most reported by 45 states and Washington, D.C. During the 2024–2025 school year, kindergartners’ MMR vaccination rates decreased to 92.5%, below the 95% threshold for herd immunity.
Public health officials are also addressing the role of misinformation.
The outbreak has also highlighted the financial burden of vaccination. By the end of June, more than 55,000 Pennsylvanians had lost Medicaid or CHIP coverage.
As the outbreak continues, public health officials are urging residents to take preventive measures, including avoiding crowded spaces and seeking medical attention if symptoms arise. The Pennsylvania Department of Health has launched a review of the sixth death, promising to update the public once its investigation is complete. We will update the public after our investigation is finished,
a department spokesperson said.
Update (October 15, 2026)
According to Fox8, health officials in Lake County, Ohio, have confirmed a possible measles exposure at the SweetBerry Fresh Market located at 30022 Euclid Ave. in Wickliffe. The potential exposure occurred between 7 a.m. and 5 p.m. on October 3, October 5, and October 7. Lake County health officials are collaborating with the individual’s healthcare team to identify known contacts to prevent further spread of the virus. While there are currently no confirmed measles cases in Lake County, officials remind the public that the virus can survive in the air for up to two hours after an infected person has coughed or sneezed.
Update (October 20, 2026)
According to Ars Technica, Pennsylvania’s health department issued a health alert Monday as measles cases in pregnancy and congenital measles continue to increase, reaching 53 cases during pregnancy as reported by The 19th earlier this month. Before this outbreak, congenital measles cases had not been seen in decades. At least one case of congenital measles resulted in a newborn baby boy dying immediately after birth while his mother was severely ill.
As of October 19, Pennsylvania reported 1,286 measles cases across 42 counties, with 247 hospitalizations and six reported deaths, though the latest death remains under state investigation. The health department advisory noted that the MMR vaccine is not recommended during pregnancy because it is a live attenuated vaccine, but exposed pregnant individuals can receive intravenous immunoglobulin if given within six days of exposure.
