House Democrats Give CDC Until Sept. 28 to Explain Zero-Death Measles Tally as Pennsylvania's Toll Hits Four

Since Pennsylvania's health department confirmed its first two measles deaths in 35 years, the state has now confirmed two more, bringing its 2026 total to four, according to The Hill and Newsweek. All four came from an outbreak Governor Josh Shapiro calls the worst in the country, with 693 cases confirmed across 38 of Pennsylvania's 67 counties as of this week.

The fight over that outbreak has moved from cable news shouting matches to a formal congressional demand. Reps. Frank Pallone Jr. (D-N.J.), Diana DeGette (D-Colo.) and Yvette Clarke (D-N.Y.), the top Democrats on the House Energy and Commerce Committee and its health and oversight subcommittees, sent a letter to new CDC Director Erica Schwartz demanding a staff briefing by September 28 on why the agency has refused to count Pennsylvania's deaths in its official weekly measles report, according to The Hill.

As of last Friday, the CDC's public dashboard showed 3,294 measles cases for 2026, up 160 in a single week, with an asterisk next to the data noting the National Center for Health Statistics hasn't recorded any deaths this year where measles was the underlying cause. Zero. Meanwhile Pennsylvania's own health department says it evaluated all four deaths using CDC's own criteria and handed over the epidemiological data.

According to The Hill, the decision to exclude Pennsylvania's deaths reportedly came directly from Schwartz, who took over the CDC this month with a stated pledge to run the agency independently of Health Secretary Robert F. Kennedy Jr. Schwartz has not publicly explained that decision, which The Hill calls a break from the CDC's normal practice of taking states' own case classifications at face value.

The underlying dispute traces back to the first two deaths, both unvaccinated Lancaster County residents, one an infant. The county coroner said the baby died of a ruptured spleen and internal hemorrhage, not measles directly, though measles was found in lung tissue and listed as a contributing condition, according to MedPage Today. Kennedy seized on that distinction, suggesting on X that the deaths "may even have been altogether fabricated" and that Shapiro's office had declined CDC's offers to help, a claim Pennsylvania's health department publicly disputed, per CNN.

Infectious disease specialist Amesh Adalja told PBS's PolitiFact that state health departments use the term "measles-associated" to track outbreaks in real time, not to assign a formal cause of death, and that it isn't unusual for a coroner and a health department to describe the same death differently. Adalja himself said the ambiguity, left unexplained, "looked to a reasonable observer like either incompetence or concealment."

But that dispute over one classification does not explain why the CDC is now declining to count Pennsylvania's other three deaths at all. Two of them have gone unaddressed by Schwartz entirely, according to the Democrats' letter. Pennsylvania's health secretary, Dr. Debra Bogen, said her department's epidemiology team verified positive measles tests in both original cases and reported them to CDC's measles response team, according to CNN.

Shapiro has kept up the pressure. In a post on X after the two newest deaths were confirmed, he said Kennedy should "stop stoking vaccine skepticism and misinformation and compromising the serious mission of the nation's public health agencies," and accused Kennedy of personally directing CDC not to report the deaths because they don't "fit his phony narrative," per Newsweek. Kennedy has not responded publicly to that specific accusation about Schwartz's decision.

Kathleen Sebelius, who ran HHS under President Obama, told NPR that Kennedy's decision to spend the week at events on regenerative farming and school nutrition rather than addressing the outbreak directly amounts to "a very intentional refusal to confront both the spread of measles throughout the country, but also the effectiveness of vaccines." HHS did not respond to NPR's question about whether Kennedy recommends the MMR vaccine to unvaccinated people in outbreak areas.

The House Democrats' September 28 deadline is now the next concrete checkpoint. Whether Schwartz appears for that briefing and whether she offers any public explanation for excluding a state's own confirmed data from the federal count remains an open question. So does whether the CDC's national tally will ever reflect Pennsylvania's four deaths, or continue to carry an asterisk instead of a number.
