The U.S. Centers for Disease Control and Prevention (CDC) is facing intense scrutiny for excluding four recent measles deaths in Pennsylvania from its national tracking dashboard.
Despite local coroners and the state health department confirming the fatalities, the CDC is holding off on counting them while working with the Council of State and Territorial Epidemiologists to set a new federal definition for a “measles death.”
The uncounted deaths involve an 18-year-old in Mifflin County who suffered a rare neurological complication, a 40-year-old woman in Jefferson County, and two unvaccinated infants in Lancaster County who died in August.

As Pennsylvania battles the worst outbreak the United States has seen in decades, experts warn that omitting the official death toll skews how seriously the public views the crisis.
Why the CDC is Changing Its Reporting
Before this outbreak, the U.S. hadn’t recorded a measles death in a decade, so the agency routinely relied on the World Health Organization’s standard definition. Now, CDC Director Erica Schwartz says the agency is revising its classification criteria to prevent unrelated deaths from being improperly attributed to the virus.
“If someone got hit by a bus, and they happened to have Covid, often that was called a Covid-related death,” Schwartz told The Guardian, pointing to past controversies surrounding cause-of-death data.
Former CDC chief medical officer Debra Houry pushed back against the comparison, noting that Pennsylvania’s health department already conducts rigorous investigations to ensure the virus directly caused each death.
“Dr. Schwartz’s comments are not only not helpful, but contribute to misinformation,” Houry told the publication. “I would focus less on the definition itself and responding to the measles outbreak, and that’s what the focus of the CDC director should be.”
Inside Pennsylvania’s Accelerating Outbreak
In Pennsylvania, health providers are actively managing an accelerating surge. The state’s official case count stands at 731, though doctors suspect the real figure is significantly higher since many infected individuals manage symptoms at home without testing. The rapid transmission has even forced clinicians to treat congenital measles in newborns who contracted the virus in utero or during birth — a diagnosis most modern physicians have never encountered in their careers.
State health officials have launched more than 100 pop-up vaccination clinics and are working with local health systems to speed up testing turnaround times. Despite those efforts, medical experts expect cases to rise further as cold weather sets in and unvaccinated students attend school together.
What happens in Pennsylvania won’t stay in Pennsylvania. If national tracking leaves out fatalities, neighboring states won’t realize how quickly an outbreak can escalate — or how much support their own hospitals might need.
