On Tuesday, the Governor of Pennsylvania, Josh Shapiro, stood in a hospital in Lancaster County and said two measles deaths were completely preventable.
On Tuesday, the Pennsylvania Department of Health called those same two deaths "measles-associated."
On Tuesday, the Lancaster County Coroner, Dr. Stephen Diamantoni, said no measles deaths had been handled by his office.
Those statements are not consistent. If the deaths were “measles-associated” rather than measles-caused, the governor’s is not easily defensible. Assembled without a bridge between them, they are a weapon, and by Wednesday afternoon RFK Jr, the Secretary of Health and Human Services of the United States, was suggesting the deaths might have been fabricated.
That escalation was not inevitable. It was manufactured out of an information vacuum that the Commonwealth created and then declined to fill.
Where the outbreak actually is
Pennsylvania has 424 confirmed measles cases this year, 94 of them diagnosed in the past week. Seventy-three people have been hospitalized. Roughly half the cases are in Lancaster County, where kindergarten MMR coverage has fallen from 95.5 percent in 2017 to 87.6 percent in the last school year. These are the first measles deaths in Pennsylvania in thirty-five years and the first reported in the United States this year.
The outbreak is also no longer a southeastern Pennsylvania story. Jefferson County has become a second hotspot in the western part of the state and accounted for at least one of the cases diagnosed in Pittsburgh. There are cases in over two dozen of Pennsylvania’s counties, including in Butler County, where I grew up, and where kindergarten coverage sits at 93.1 percent — respectable, still short of the 95 percent that reliably stops transmission of a virus this contagious.
That is the operational picture. Almost none of the last forty-eight hours has been spent on it.
The newborn
The Lancaster County Coroner has said his office is investigating the death of a newborn who tested positive for measles and died of a splenic laceration. He has said the cause of death was not measles. Postmortem testing showed measles antibodies.
Here is what nobody arguing about this on X is doing: asking the right question.
A splenic rupture or laceration is a mechanical event. The capsule tears and the infant bleeds. Measles does not rupture a spleen. What measles might do — the literature on this is sparse — is produce splenomegaly, and an enlarged spleen is considerably more fragile under the mechanical stress of delivery than a normal one. So, the question is not "measles or rupture." The question is whether measles had any role in enlarging this spleen enough that an otherwise survivable delivery inflicted a lethal splenic laceration.
Answering it requires an actual workup which would include, at bare minimum:
· Revealing whether the antibodies found in the infant were IgG antibodies transferred from the mother trans-placenta or evidence of new infection (IgM)?
· Was PCR testing done?
· Maternal serology, vaccination status, and if there was a maternal rash
The state announced a conclusion in language that declined to conclude anything. The coroner, more carefully, offered a cause of death while the investigation that would establish it was still open — and that determination traveled far faster and far further than the caveats attached to it. Neither office got ahead of the science. Both got ahead of the public’s ability to interpret them.
"Measles-associated" is correct, and it was a catastrophe
The Department of Health uses "measles-associated" when laboratory or epidemiologic evidence of measles is present but the medical certifier or coroner has not determined measles to be the immediate cause of death. That is the right epidemiologic category before a causal workup is complete. It is honest uncertainty, properly labeled.
The failure is that a hedge and a certainty were deployed by the same administration inside twenty-four hours. You cannot say "we are not yet asserting causation" through your health department and "completely preventable" through your governor and expect anyone to read the pair as coherent. Pick one and hold it. Either you believe measles caused these deaths and you show your evidence, or you do not yet know and you publish the timeline on which you will.
Pennsylvania did neither, and got the worst of both.
Confidentiality was a choice, not a wall
The Department declined to release any detail that could identify the decedents, citing privacy as a core responsibility. Age, location, clinical course, community affiliation — all withheld.
Pennsylvania's confidentiality provision for communicable disease case reports is 28 Pa. Code § 27.5a. The section does make case reports confidential. It also contains an express exception: disclosure is permitted when necessary to carry out a purpose of the Disease Prevention and Control Law of 1955, as determined by the Department. Preventing further deaths during an active, accelerating outbreak sits about as squarely inside the purpose of a disease control statute as anything can.
And confidentiality was never the binding constraint anyway, because there is an enormous space of disclosure that identifies no one in a county of half a million people:
· Age band
· Vaccination status of the decedent, and of the mother where relevant
· Whether hospitalized, and the clinical course
· The specific complication
· Whether measles is expected to appear on the death certificate
· The date by which a final determination will be made and announced
None of that is a name. None of that is an address. The Commonwealth chose the narrowest available reading of an exception it was legally free to read generously, and then appeared surprised when the silence filled with something considerably worse than the truth.
What the vacuum is for
The anti-vaccine movement does not need to win an argument. It needs a gap.
And it did not need to invent anything here, because the frame was pre-built. "Died OF versus died WITH" is not a new argument about measles. It is the COVID death-certificate template, recycled intact, down to the capitalization. Lancaster County commissioner Josh Parsons deployed it on X within hours. The movement had the artifact ready and waiting; Pennsylvania supplied the occasion.
This is why institutional silence functions as an accelerant. To an already skeptical public, a health department that will not answer an answerable question does not read as careful. It reads as concealing something — which is precisely the story that has been told about public health institutions for two hundred years, and the single most durable asset the movement owns.
None of which excuses what came next. When the sitting Secretary of Health and Human Services says on national television that no measles deaths can be found in Lancaster County and floats the possibility that a state fabricated them, that is not a fringe rumor on a forum. That is the most powerful health official in the country lending an official seal to a counter-narrative, about children, during an outbreak his own department is nominally helping to contain. He owns that. He also did it into a vacuum he did not have to create, because Harrisburg built it for him.
The trap
Not all deaths in Pennsylvania are referred to a coroner or medical examiner, and Dr. Diamantoni might not yet have had situational awareness. He offered several ordinary explanations for the gap between his numbers and the state’s: his office may simply not have received the information yet, or a severely ill patient may have been treated at a specialized facility outside Lancaster County, in which case that county’s coroner would handle the death. Asked directly whether the discrepancy was a matter of state classification, he said he couldn’t speak to what the Governor or the state would decide.
The coroner was describing his office's formal case log. The Governor was describing the outbreak's toll. Two officials, two data systems, two different questions, both answered accurately, and nobody behind a podium in the Commonwealth stood up and explained why both could be true at once until the contradiction had already hardened into evidence of a cover-up.
A press operation's entire job in an outbreak is to make sure that gap never becomes visible. This one made it the story.
If I were teaching public health communication, I would use this week as the case study in how not to do it. It is an unforced error, and it is much better to be transparent than to spend the week trying to score points against Robert F. Kennedy Jr.
My stake in this is not abstract. I am an infectious disease, emergency medicine, and critical care physician who takes care of patients in Pittsburgh and Butler County hospitals, and I spend a large part of every week explaining this virus — to reporters, to audiences, and to people who are not ideologues but are genuinely unsure what to believe. This week made every part of that job harder. The anti-vaccine movement is emboldened, and it did not have to earn it. Pennsylvania’s health officials now look to a substantial portion of the public like people who were being either dishonest or manipulative, which is corrosive in a way that outlasts this outbreak by years. And the person who was merely hesitant last month has now watched a governor, a coroner, and the Secretary of Health and Human Services contradict each other about whether two people died, which is precisely the kind of spectacle that converts hesitancy into conviction. That conviction does not stay in the exam room. It becomes unvaccinated kindergarteners, and unvaccinated kindergarteners become measles cases, and measles cases eventually become the thing everyone this week has been arguing about whether we actually had.
What Harrisburg should do tomorrow
1. One statement, three signatures: DOH, the Lancaster County Coroner, and the Governor's office jointly, explicitly reconciling "measles-associated" with "no measles deaths handled by our office," and stating plainly why both are true.
2. Release the non-identifying clinical details on both deaths now — including everything in the list above regarding the infant death. It identifies no one and it ends the speculation.
3. Publish the investigation timeline: Which tests are running — genotyping, IgM/IgG serology, histopathology — and the date a determination will be announced. Give the vacuum a stated expiration.
4. Rebut "fabricated" with evidence, not with adjectives. Lab confirmations, genotype, epidemiologic linkage, and an invitation to independent verification. Calling something a conspiracy theory and stopping there is not a rebuttal; it is a press release.
5. Get ahead of the next data point rather than answering it a news cycle too late.
This is an operational response, not a political one. It needs politics removed from it — from both parties — so that public health workers and infectious disease physicians can get control of an outbreak that is still growing.
Decreasing the susceptible pool is more important than who wins
Vaccine exemptions in Pennsylvania have tripled. School is starting right now, which means the densest mixing of the age group most likely to be under-vaccinated is about to occur in all 67 counties simultaneously.
The virus does not care whether the Governor or RFK Jr. wins the argument. It does not wait for a coroner's report. All it requires is susceptible hosts sharing air, and there are more susceptible people in the United States right now than at any point in the modern era.
Every week spent on political oxygen instead of vaccination appointments leaves that pool exactly the size it is today. The biology is indifferent to all of it, and the biology is the only thing here that gets a vote.
This is horrifying. Thank-you for seeing so clearly, Dr. Adalja, and for writing so beautifully.
Outstanding analysis of a collection of awful unforced errors. Three different public officials, each simultaneously stepping on a rake.
