Four Pennsylvania Measles Deaths Sit on Two Official Tallies

Pennsylvania confirmed 903 measles cases on Sept. 28, along with 176 hospital stays and four deaths the state ties to the virus. The CDC’s national board lists two measles deaths for 2026.

The Pennsylvania measles outbreak now touches 39 of the state’s 67 counties, but it is still a two-county epidemic wearing a statewide label, and a fight over how a measles death gets written down.

Two Counties Still Account for Half the Cases

The Department of Health’s Sept. 28 bulletin put 903 measles cases across 39 counties, 13 of them new since Sept. 25. Lancaster County had 363. Mifflin County had 105. Those two counties hold 468 of the 903 confirmed infections, just over half the state’s load.

Four of the 903 people were fully vaccinated, less than 1 percent. About 1 in 5 confirmed patients, 176 people, have been hospitalized. State health-center staff have given more than 7,900 MMR doses in 2026, and more than 5,300 of those shots went out at 173 pop-up clinics in the hardest-hit towns since the outbreak began in late April.

WHERE THE 903 CASES SIT

The CDC’s public map still showed 850 Pennsylvania cases as of Sept. 24, a lag behind Harrisburg’s later count. Nationally the agency has 3,659 confirmed measles cases for 2026, already above the 2,289 recorded in all of 2025, with 95 percent of this year’s infections tied to outbreaks. Among those national cases, 95 percent are in people who were unvaccinated or whose status is unknown. Nine percent, 327 people, have been hospitalized.

Measles spreads when an infected person breathes, coughs, or sneezes, and the virus can stay infectious in the air and on surfaces for up to two hours. Symptoms can start 7 to 21 days after exposure. The health department puts the death risk at 1 to 3 patients per 1,000 cases and says two documented MMR doses give 97 percent lifetime protection. People who think they were exposed can call 877-724-3258.

Four Deaths, Two Official Tallies

Pennsylvania had not recorded a measles-associated death since 1991. It has now recorded four in one season, and Washington has accepted two of them for the national board. The people behind those numbers are not interchangeable, which is why the argument will not die with a press release.

THE FOUR DEATHS PENNSYLVANIA COUNTS

• Lancaster newborn: Tested positive for measles. Lancaster County Coroner Dr. Stephen Diamantoni said the immediate cause was a lacerated spleen and that measles did not contribute. State epidemiologists still list the death as measles-associated, saying measles can enlarge the spleen and make a rupture more likely.
• Lancaster 6-week-old: Diamantoni later said this infant died of measles. The child had Amish lethal microcephaly, a rare genetic condition, had been on palliative care from birth, and was too young for MMR.
• Mifflin County 18-year-old: Unvaccinated. The Mifflin County coroner said the death came from acute disseminated encephalomyelitis, a rare brain inflammation that can follow measles. The health department listed the death on Sept. 15.
• Jefferson County 40-year-old woman: Unvaccinated. County officials said she died of measles complications. The state listed that death the same day as the Mifflin case.

Health Secretary Dr. Debra Bogen said both of the Sept. 15 deaths met the state’s tests after work with those coroners: clinical measles, a positive lab result, and no unrelated cause such as a crash. Gov. Josh Shapiro, speaking on Aug. 25 after the first two Lancaster deaths, put the risk in plainer terms.

As a father of four children, I know every parent wants what’s best for their kids, but right now, there’s a barrage of information thrown at us online, on TV, and in our daily lives. I want every Pennsylvanian to know this: measles does not care about your county, your faith, or your social circle.

Gov. Josh Shapiro, Aug. 25, 2026, Lancaster

HHS Secretary Robert F. Kennedy Jr. accused Shapiro of politicizing the infant deaths and, according to people familiar with the exchange, asked CDC Director Dr. Erica Schwartz to keep Pennsylvania’s fatalities off the national weekly board. CDC staff had already taken the state’s characterization before that request. On Sept. 4, Kennedy posted that Diamantoni had attributed only the second infant’s death to measles and that the National Center for Health Statistics had no 2026 death records listing measles as the underlying cause.

The facts emerging now demonstrate why CDC waited for the evidence rather than allowing political grandstanding to dictate its reporting. Governor Shapiro, by contrast, politicized these two tragic deaths before the underlying causes had been established.

How Pennsylvania Counts a Measles Death

There is still no national measles-death definition of the kind used for flu or RSV. The Council of State and Territorial Epidemiologists is writing one with the CDC. Until that lands, Harrisburg published its own case definition for measles-associated death, modeled on those other respiratory-death rules, and that document is now doing national political work.

MEASLES-ASSOCIATED DEATH

• The term: Pennsylvania counts a confirmed measles-associated death when a person with clinical measles and a positive lab test dies within 30 days of symptom onset, and the death is not from an unrelated cause such as a motor-vehicle crash.

A death more than 30 days after rash onset does not count, and neither does a death after a full recovery. Supporting records and known exposure are part of the file. That is a surveillance rule, not a bedside diagnosis, and it is broader than “measles was the underlying cause on the death certificate,” which is the clock CDC now says it is using.

The first infant is the hard case under both tests. Diamantoni has not moved off the lacerated spleen. The state has not moved off “associated.” The 6-week-old, the 18-year-old with ADEM, and the 40-year-old woman are much closer to a classic measles death, which is why a federal tally of two against a state tally of four can both be internally consistent and still leave families in the gap.

Nurses Bring the Shot to the Kitchen Table

Pop-up clinics are the public face of the response. The quieter one is a nurse in a kitchen. Chester County, which shares a long border with Lancaster, has given 538 MMR doses in this outbreak, 340 of them in private homes rather than clinics. Health Director Jeanne Franklin said her staff reused a method from Covid: knock, explain the outbreak, and offer the shot on the spot.

People have called up and said, I can’t get to your clinic, or, I don’t want people to know I’ve changed my mind.

Nurse Dale Weiser has been driving those routes, sometimes daily, vaccinating families at the table. She has said many of the people she meets have no insurance and little contact with clinics, and had not seen a reason to get the shot until measles was already in the next house. Franklin has described the work as MMR only, not a pile of other vaccines, because trust in those rooms is thin and easy to spend.

The geography matches the culture the state has named without always putting it in the lede. High case counts include Mennonite and Amish households that often skip routine care. Claudia Beiler, a Mennonite mother of five in the Lancaster area, said last summer that families she knows treat measles at home and that some infected children never reach an official count. “Many of us hold the belief that measles can be conquered at home,” she said. If she is right about hidden illness, 903 is a floor.

Providers across the state are not waiting on those households. They usually give about 25,000 MMR doses in a month. In August they gave more than 49,000. In the first three weeks of September they gave more than 38,000. Dozens more pop-up clinics are on the calendar, the department said, based on community interest and need. Interest is not the same thing as a kitchen door opening.

Why School MMR Rates Were Already Thin

Measles needs about 95 percent two-dose coverage to stop community spread. Pennsylvania’s own school survey for 2025-26 put kindergarten MMR at 93.2 percent, seventh grade at 94.6 percent, and 12th grade at 96.9 percent. More than half of reporting schools met the 95 percent line in kindergarten, and more than 200 posted 100 percent, but a large minority did not, and the holes are not randomly placed.

THE COVERAGE THE OUTBREAK WALKED INTO

• Pennsylvania kindergarten MMR: 93.2 percent with two doses in 2025-26, below the 95 percent community-immunity line.
• National kindergarten MMR: kindergarten MMR coverage of 92.4% in the same school year, with 4.2 percent of kindergartners exempt from one or more shots, the highest U.S. exemption rate on that series.
• Pennsylvania’s exemption rules: The state allows medical, religious, and personal belief opt-outs, which is the legal gap sitting under the Lancaster and Mifflin maps.
• Early MMR: After the first deaths, the health department told clinicians they could start MMR at 6 months in outbreak areas, months before the usual first-birthday dose.

On Aug. 25, when the state still had 393 cases in 29 counties, Shapiro’s office was already sending school nurses the same warning. More than 1,000 clinicians had sat through measles briefings, because most practicing doctors in the state had never treated a case. Nearly 1,000 school nurses joined those sessions as classrooms reopened. The coverage problem was not a surprise that arrived with the rash. It was in the spreadsheet before late April.

Harrisburg Withdrew Its Disease-Control Rules

On Sept. 25, three days before the 903-case update, the health department pulled a 502-page rewrite of its contagious and noncontagious disease rules, the first serious attempt to update that code since 2001. The draft would have widened the list of diseases providers must report, tightened how immunization and infection data move, and given health officials clearer power to act in an outbreak. The comment file ran past 10,000 submissions, and most of the noise was opposition that treated the package as a return of Covid-era controls.

DOH spokesperson Neil Ruhland said the department would revise the draft and file it again once that feedback is in the text. Secretary Bogen told the Independent Regulatory Review Commission the agency was making further changes and would resubmit later. House Republicans called the withdrawal a win against overreach. The measles dashboard did not pause while the lawyers argued. Thirteen more cases landed between Sept. 25 and Sept. 28.

Bogen had already tied federal field help to the death dispute. In a mid-September letter to Schwartz she said Pennsylvania was seeking a CDC Epi-Aid, then warned that if the agency would not recognize the four deaths, the department would pull the request. Kennedy said he had not ordered anyone to suppress Pennsylvania’s fatalities and that CDC would count measles-caused deaths when NCHS sees measles as the underlying cause on records the states submit. Those are two different machines. They are now both running on the same four bodies.

The Federal Count Now Waits on Death Certificates

For a generation, CDC’s weekly measles board took death reports from state health departments. After the Lancaster announcement, the agency moved the national death number onto NCHS vital records, a slower feed, and began work with CSTE on a standard measles-death definition. The fetched CDC page, updated Sept. 25, lists two U.S. measles deaths in 2026 against three in 2025, with an asterisk that the figure can change as reviews finish.

HOW THE TWO TALLIES GOT THIS FAR APART

1. Late April 2026: Pennsylvania’s outbreak is identified. Pop-up MMR clinics start in the affected towns.
2. Aug. 25, 2026: The state announces two measles-associated deaths in Lancaster County, the first in 35 years, with 393 cases in 29 counties.
3. Aug. 26 to Aug. 31, 2026: Kennedy disputes the deaths. CDC omits them from the weekly board after Schwartz’s direction, departing from the old practice of posting state death reports.
4. Sept. 4, 2026: Diamantoni says the 6-week-old died of measles. Kennedy posts that NCHS has no measles death records yet and that the first infant died of a lacerated spleen.
5. Sept. 15, 2026: Pennsylvania adds the Mifflin 18-year-old and the Jefferson 40-year-old. The state case count is 693 in 38 counties.
6. Sept. 24 to Sept. 28, 2026: CDC’s public table shows 3,659 U.S. cases and two deaths. Pennsylvania’s table shows 903 cases, 176 hospitalizations, and four deaths.

Last year’s three U.S. measles deaths went onto the federal board the old way, from states. The new path runs through death certificates that can take months to land. That is a change in what the country is willing to say out loud while an outbreak is still producing patients. It does not change the rash in Lancaster, the ADEM file in Mifflin, or the kitchen visits in Chester County.

The clinics are still open. The two death numbers are still both posted. Lancaster still has 363 confirmed infections, Mifflin still has 105, and the national board still trails the state by a week and by two lives.
