Pennsylvania Governor Josh Shapiro (D), President Donald Trump, and Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. traded public criticisms on Friday, Sept. 18, 2026, regarding a measles outbreak in Pennsylvania. During an appearance in the Oval Office, Trump described Shapiro as a "bad governor" who is "close to incompetent," while Kennedy accused the governor of refusing to cooperate with the Centers for Disease Control and Prevention (CDC). Shapiro responded on social media, stating that "incompetence is letting measles... reemerge" and accusing the administration of denying the reality of four measles-associated deaths in his state.
The dispute centers on a year for measles in the U.S. with cases at a 35-year high. Pennsylvania has reported nearly 800 cases and four deaths in 2026, which Shapiro says have been certified by the state Department of Health and three independent coroners. However, the CDC's dashboard does not currently list any measles deaths for 2026, stating that the National Center for Health Statistics lacks death records indicating measles as the underlying cause. Kennedy has acknowledged only one death, involving a six-week-old infant with Amish lethal microcephaly, stating he "waited for the evidence" before attributing the case to measles.
Pennsylvania Health Secretary Debra Bogen has formally requested emergency assistance from the CDC's Epi-Aid program, but the state is conditioning its acceptance on the agency's public acknowledgment of the four deaths. Kennedy countered that the administration ended outbreaks in South Dakota and Texas by sending in epidemiological teams, but claimed Shapiro declined similar help. In an interview, Shapiro stated he would not change his response and urged Kennedy to join him in calling for vaccinations rather than "stoking this vaccine skepticism."
On a broader scale, the incident highlights a shift in federal public health reporting. With U.S. measles cases and deaths at their highest levels since 1992, the discrepancy between state-certified death records and the CDC's national dashboard creates uncertainty regarding the mortality rate of the current outbreak. For households, this may lead to conflicting information about the severity of local health risks and the necessity of the MMR (measles, mumps, and rubella) vaccine, which Shapiro notes was used to declare the disease eliminated in the U.S. in 2000.
The clash could influence how future infectious disease outbreaks are managed between the federal government and individual states. If the CDC continues to omit state-certified deaths from its public data, it may hinder the "administrative process" used to trigger federal resources. What happens next depends on the CDC's response to Secretary Bogen's letter; the agency must decide whether to acknowledge the four deaths as a condition for Pennsylvania accepting federal on-the-ground assistance. No specific deadline for this decision was reported.
