CDC’s Measles Death U-Turn Stirs Fears on Agency Reliability

Federal health officials have removed two Pennsylvania measles deaths from the Centers for Disease Control and Prevention’s official national tally, a reversal that public health experts warn signals a breakdown in trust between state and federal authorities as the country heads into a demanding fall and winter disease season.

The dispute centers on two unvaccinated Lancaster County residents — at least one a newborn — whose deaths Pennsylvania officials announced on August 25 as the commonwealth’s first measles-associated fatalities in 35 years. Within days, Health and Human Services Secretary Robert F. Kennedy Jr. publicly questioned whether the deaths had occurred at all, and the CDC quietly stopped counting them.

The episode, first detailed by NPR, has unsettled independent public health authorities and raised questions about whether the nation’s premier disease-fighting agency can be relied upon as other outbreaks loom.

A Reversal in Three Weeks

According to the Pennsylvania Department of Health, both individuals were unvaccinated Lancaster County residents, and the deaths marked the first measles-related losses in the commonwealth in 35 years. Lancaster County has recorded more measles cases than any other part of the state.

The trouble began the same day. Lancaster County Commissioner Josh Parsons posted on X that the county coroner’s office had “ZERO reported cases where measles is the immediate cause of death,” describing one case as a person who died “WITH measles, but not FROM measles.” The following day, speaking in Tampa, Kennedy seized on the discrepancy. “They cannot find any measles deaths in Lancaster County,” he said, adding that officials were “trying to figure out who those deaths were and whether they actually happened.” He later suggested on X that the deaths may have been “fabricated by one of the Governor’s hopeful staffers.”

Pennsylvania’s own timeline, compiled by PolitiFact, shows that the state health department had thoroughly investigated and verified that both individuals tested positive for measles. The state explained that it uses the term “measles-associated” when laboratory or epidemiologic evidence of measles is present, even if a coroner does not certify the disease as the immediate cause of death — a standard distinction that is not necessarily a contradiction.

By August 30, the CDC announced it would not include the two deaths in its count while it reviewed the cases. Then, per an exclusive Reuters report, three sources said Kennedy personally asked his newly installed CDC director to remove the reference to the deaths — and that Director Erica Schwartz implemented the directive without objection.

As of September 11, the CDC had excluded the Pennsylvania deaths from its tally for three consecutive weeks, according to NPR.

A Data Picture That Is Growing Harder to Read

The reversal matters because the stakes of national surveillance are rising. The CDC’s own measles dashboard shows 3,294 confirmed cases in 2026 as of September 10 — the worst resurgence in decades — with 95% of cases occurring in people who are unvaccinated or of unknown vaccination status. Hospitalizations have reached 267, and the agency notes that no death records from 2026 currently list measles as the underlying cause.

That framing is precisely what worries former officials. “Red flag. Red alert. This is not normal,” said Dr. Demetre Daskalakis, who resigned as director of the CDC’s National Center for Immunization and Respiratory Diseases to protest what he called political interference. “When they raise doubt on the adjudication that a state may have made around a death, that is highly problematic… This is dangerous.”

Dr. Anne Zink, a senior fellow at the Yale School of Public Health and former president of the Association of State and Territorial Health Officers, described a broader erosion: “What we have been seeing, that got amplified even more with these measles cases, is a breakdown in the coordination and trust between states and the federal government.”

Dr. Georges Benjamin, executive director of the American Public Health Association, put the concern bluntly: “We need to have good solid evidence-based national data. And I’m obviously concerned that it will happen again for other infectious diseases… If it happens with flu and with COVID, the question is: Who can we rely on for the data on a national level?”

A New Director Under Pressure

The controversy also tests Dr. Schwartz, confirmed as CDC director on August 5 by a narrow 51–44 Senate vote — the third nominee for the role in 18 months. She inherited an agency NPR described as “demoralized and diminished” after months of tumult and waves of staff cuts.

Dr. Debra Houry, who resigned as the CDC’s chief medical officer alongside Daskalakis, said the director’s priorities appear misplaced. “What the director should be doing instead of looking into these disease counts is responding to the outbreak itself,” Houry said. “I haven’t heard from her talking about the importance of getting kindergarteners vaccinated when we’re seeing declining rates. It’s back to school time around the United States. We need her to step up publicly to talk about what can be done.”

Neither the CDC nor HHS responded to NPR’s repeated requests for comment. An HHS spokesperson told Reuters only that the agency had “requested details necessary to determine whether measles caused or contributed to the deaths,” citing conflicting accounts between county and state officials.

Why the Dispute Echoes COVID-19

The fight over whether a person died “with” or “from” a disease is a familiar one. During the pandemic, social media users falsely claimed COVID-19 death counts were inflated by counting people who died “with, not from” the virus — a claim PolitiFact has repeatedly rated false. Kennedy himself invoked “the Democrats’ COVID playbook” in questioning the Pennsylvania deaths.

Experts note the two determinations are not mutually exclusive. A coroner establishes the specific chain of events that caused death, while a health department tracks outbreak-associated deaths in real time. A person can carry a measles infection that contributes to death without measles being the single certified cause.

What compounds the problem, infectious disease specialists told PolitiFact, is the limited public information about the victims — a gap that misinformation and conspiracy theories have rushed to fill.

What to Watch

Several questions remain unresolved. It is unclear whether the CDC will eventually reinstate the two Pennsylvania deaths, whether Director Schwartz will publicly address vaccination and the outbreak, and whether state-federal data-sharing will deteriorate further as flu, COVID-19 and RSV season arrives.

For public health officials, the more consequential issue is trust. National surveillance works only when states report data and the federal government relays it credibly. If that chain weakens, the consequences extend well beyond one state’s death count — complicating the nation’s ability to spot trends, target resources and persuade a wary public to act on official guidance.
