Pennsylvania Reports Its First Measles Deaths in 35 Years as National Outbreak Hits Historic Levels

2026-08-25
The Confirmed Deaths

The Pennsylvania Department of Health confirmed Tuesday that two people have died from measles-associated complications, both of them unvaccinated Lancaster County residents. These mark the first measles-related deaths in the Commonwealth in 35 years, and the first measles deaths reported anywhere in the United States in 2026. The department said it will not release the victims' ages or identities, citing the privacy of the individuals and their families.

Pennsylvania Secretary of Health Dr. Debra Bogen offered condolences in a statement: "My deepest sympathies are with the loved ones who are facing this unimaginable loss." She went on to note that because measles had been largely eliminated in Pennsylvania for more than three decades, "people are not familiar with this disease and don't fully understand the potential severity of the illness," adding, "As a physician, I want to make sure that people understand that the MMR vaccine is safe and provides the best protection we have against measles."

Lancaster County at the Center of a Growing Outbreak

The deaths come amid an intensifying outbreak concentrated in Lancaster County, which has recorded 177 measles infections since April. Statewide, Pennsylvania has confirmed 393 cases across 28 to 29 counties (reports vary slightly on the exact county count) so far this year, with 86 of those cases diagnosed in just the past week, a sign the outbreak continues to accelerate rather than slow down.

A National Picture Not Seen in Over Three Decades

Pennsylvania's outbreak is playing out against a much larger national surge. According to the CDC, 2,777 measles cases have been reported across the United States this year, the highest annual total since 1991, 35 years ago. About 94% of those cases are linked to 36 separate outbreaks nationwide, and as of August 20, roughly 7% of infected people, 193 total, have required hospitalization. The majority of those infected, consistent with the pattern in Pennsylvania, are unvaccinated.

This year's Pennsylvania deaths follow three measles deaths reported in the U.S. last year: an adult in New Mexico and two young girls in Texas, the first American measles deaths in decades at the time.

Why Vaccination Rates Matter Here

Health officials have repeatedly tied the resurgence to declining childhood vaccination rates. Two doses of the MMR (measles-mumps-rubella) vaccine provide 97% lifetime protection against the disease, one dose provides roughly 93%. But CDC data shows kindergarten MMR vaccination coverage has declined for three consecutive school years, falling to 92.4% in the 2025–2026 school year, down from 95.2% in 2019–2020, before the COVID-19 pandemic. That downward trend matters because measles requires very high community vaccination rates, generally cited around 95%, to maintain the kind of herd immunity that prevents sustained outbreaks; falling meaningfully below that threshold creates exactly the conditions seen in Lancaster County this year.

Dr. Paul Offit, director of the Vaccine Education Center at Children's Hospital of Philadelphia, was blunt about the underlying takeaway: "These deaths are entirely preventable."

Why Measles Remains So Dangerous

Measles is among the most contagious viral diseases known, capable of spreading through coughing, sneezing, or simply breathing near an infected person, and the virus can remain infectious in the air for up to two hours after an infected person has left a room. Early symptoms include fever, cough, runny nose, and red, watery eyes, with the characteristic rash typically appearing a few days later, starting on the head and spreading downward. Symptoms generally emerge seven to 21 days after exposure. While death from measles is rare, it occurs in an estimated 1 to 3 out of every 1,000 cases, and the disease can cause serious complications including pneumonia and swelling of the brain (encephalitis).

What Pennsylvania Officials Are Recommending

In response to the outbreak, Pennsylvania health officials are now recommending early or catch-up MMR vaccine doses for anyone as young as 6 months old who isn't already fully protected, a notably younger threshold than the standard vaccination schedule, reflecting the elevated exposure risk in affected areas.

The Political Backdrop

The deaths were confirmed roughly two weeks after President Trump signed a vaccine-related executive order at the White House alongside Health and Human Services Secretary Robert F. Kennedy Jr., a longtime vaccine skeptic. Neither CNN's nor other outlets' reporting on the Pennsylvania deaths detailed the specific contents of that executive order in connection with this story, but the timing places the deaths within an active and closely watched national debate over vaccine policy at the federal level.

What Comes Next

As of the latest reporting, Lancaster County remains the epicenter of Pennsylvania's outbreak, and state officials have not indicated any sign the case count has peaked. With the national case total already the highest in 35 years and still climbing, health officials in Pennsylvania and nationally continue to point to MMR vaccination as the primary tool available to prevent further deaths, particularly as the current outbreak shows no clear signs of slowing.

This story involves ongoing public health developments; if you have questions about your own or a family member's vaccination status, contacting a healthcare provider or local health department is the most reliable next step.
