Pennsylvania and Wisconsin have each added one more measles-associated death, raising the United States total to ten deaths this year. The Wisconsin Department of Health Services confirmed the death of an infant on Friday, while the Pennsylvania Department of Health identified the latest fatality as an unvaccinated patient who tested positive for measles.
State reports increase death toll
With the new reports, Pennsylvania’s death count stands at seven and Wisconsin’s at two. Earlier in the outbreak, New York announced on November 2 that a child had died, marking the state’s first measles death in more than three decades. Across the country, more than 5,400 confirmed measles cases have been recorded, according to data compiled by the Centers for Disease Control and Prevention (CDC) and the Johns Hopkins University International Vaccine Access Center tracker. That figure is more than double the 2,289 cases reported for the previous year.
State health agencies continue to track cases closely. As of Friday, Pennsylvania logged 1,542 confirmed infections this year, while Wisconsin reported 651. Local and state health departments have intensified vaccination campaigns in response to the surge.
Dispute over national death count
The CDC’s official website lists six measles-related deaths, a figure that is half of the ten deaths reported by state officials. The discrepancy has become a point of contention. U.S. Health Secretary Robert F. Kennedy Jr. asked CDC director Erica Schwartz not to include the additional deaths in the federal tally, arguing that there is no evidence they were measles-associated. The disagreement pits the federal count against the classification used by Pennsylvania Governor Josh Shapiro and state health officials.
Pennsylvania defines a “measles-associated” death as one that occurs within 30 days of symptom onset in a person with confirmed measles, unless the death results from an unrelated event. The CDC is working with the Council of State and Territorial Epidemiologists to develop a standardized definition that could reconcile the differing numbers.
Infectious disease experts warn that the debate could undermine long‑standing practices for tracking measles mortality. Epidemiologists quoted by Al Jazeera noted that counting “measles-associated” deaths has been a standard approach for both the World Health Organization and the CDC.
Vaccination gaps and elimination status threatened
Measles was declared eliminated in the United States in 2000, a status that requires the country to interrupt transmission for at least 12 consecutive months. The current outbreak threatens that achievement, with officials warning that the nation could lose its elimination status within the week.
One factor cited for the resurgence is a decline in vaccination coverage among kindergarteners, which fell from 95.2 percent in the 2019‑2020 school year to 92.4 percent in the 2025‑2026 year. The measles, mumps and rubella (MMR) vaccine provides roughly 97 percent protection after two doses, underscoring the importance of maintaining high immunization rates.
Health authorities at the federal, state and local levels are urging parents to ensure children receive the full MMR series. As the nation grapples with the highest number of cases in 35 years, the alignment of death‑count definitions and renewed vaccination efforts will be critical to restoring the United States’ measles‑free status.
