CDC’s Measles Death Reversal Fuels Trust Fears

The Centers for Disease Control and Prevention (CDC) removed two measles-associated deaths in Pennsylvania from its national tally after Health and Human Services Secretary Robert F. Kennedy Jr. publicly questioned them, a reversal that public health experts say threatens the reliability of federal health data just as flu, COVID-19 and RSV season approaches. The episode has amplified concerns about a breakdown in trust between states and the federal government — and about the leadership of the agency’s new director.

According to NPR, the two deaths in Lancaster County, Pennsylvania — reported in August 2026 — were the state’s first measles-related deaths in 35 years and the first U.S. measles deaths of the year. Pennsylvania flagged them to the CDC on Aug. 25, and the agency initially reflected them in its national count.

A Reversal That Experts Call Unprecedented

Over the weekend of Aug. 29–31, the CDC removed the deaths, replacing the figure with an asterisk and an explanatory note. The agency said it would not include the deaths “while CDC reviews additional information regarding the circumstances and causes of death,” adding that available information “does not establish whether measles caused or contributed to the deaths or whether the individuals died from other causes while infected with measles.”

The move was highly unusual. When states report measles deaths — as Texas and New Mexico did in 2025 — the CDC normally adds them to its national tally without adjudicating the cause. One of the deceased was a newborn whose death the Lancaster County coroner initially attributed to a ruptured spleen; a postmortem test of the baby’s lung tissue showed a measles infection acquired before birth. On Sept. 10, a Pennsylvania coroner released details confirming the virus itself caused at least one of the deaths.

“Red flag. Red alert,” 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.”

Kennedy Disputes the Deaths

Kennedy’s public dispute with Pennsylvania was itself without precedent. The health secretary suggested on social media that the deaths may have been “fabricated” by Gov. Josh Shapiro’s administration and gave an incorrect tally of U.S. measles deaths in a Fox News interview, saying “in 10 years, there have been three measles deaths in America.”

Shapiro, a Democrat, pushed back sharply. “There are real-life consequences to spreading misinformation,” he said, arguing that Kennedy’s language undermining confidence in vetted medical guidance is contributing to outbreaks.

An HHS spokesperson defended the agency’s position, saying the CDC “has a responsibility to ensure its reporting accurately and transparently reflects what is known and what remains unconfirmed.”

Neither the CDC nor HHS responded to NPR’s repeated requests for comment.

A Breakdown in Federal-State Trust

Beyond the disputed tallies, experts describe a broader erosion of the working relationship between state and federal health officials that is essential to outbreak response.

“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,” said 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. “These partnerships are critical and essential to making us healthy and well.”

Pennsylvania has recorded almost 500 measles cases in 2026 across 29 counties, with Lancaster County the epicenter at nearly 200 confirmed cases. Local officials say the true count is likely higher. The NPR reporting on the clash captured how the dispute unfolded, with Kennedy questioning whether the deaths “actually happened” and former HHS Secretary Kathleen Sebelius accusing him of an “intentional refusal to confront” the spread of measles.

Implications for Other Diseases

The concern is not limited to measles. Experts warn that if federal data can be altered under political pressure, the reliability of national reporting on flu, COVID-19 and RSV could be drawn into question during a season when coordinated surveillance matters most.

“We need to have good solid evidence-based national data. And I’m obviously concerned that it will happen again for other infectious diseases,” said Dr. Georges Benjamin, executive director of the American Public Health Association. “If it happens with flu and with COVID, the question is: Who can we rely on for the data on a national level. More people will get sick… They won’t know who to trust. And that is the problem here.”

The episode also casts a shadow over the new CDC director, Dr. Erica Schwartz, who took over after a tumultuous year that left the agency demoralized and diminished. Many hoped Schwartz — a well-respected physician and attorney — would restore credibility by pushing back against political pressure.

“What the director should be doing instead of looking into these disease counts is responding to the outbreak itself,” said Dr. Debra Houry, who resigned as the CDC’s chief medical officer at the same time as Daskalakis. “I haven’t heard from her talking about the importance of getting kindergarteners vaccinated when we’re seeing declining rates.”

Dr. Paul Offit, a vaccine safety expert at the Children’s Hospital of Philadelphia, put the stakes bluntly regarding the Pennsylvania cases: “These patients would not have died were it not for measles.”

What’s Next

The immediate question is whether the CDC will restore the two deaths to its national tally after the coroner’s confirmation that the virus caused at least one death, and whether Schwartz will publicly address the outbreak and falling vaccination rates. The longer-term concern is whether states and the public can trust federal health data as seasonal disease pressures build — a test that will play out in the coming weeks and months.
