Measles toll climbs to 4,588 amid data disputes
Federal and state officials disagree on death counts as 178 new cases are logged across 43 active outbreaks.

The Centers for Disease Control and Prevention logged 178 new measles cases in the United States this week, bringing the 2026 total to 4,588. The agency attributed the infections to at least 43 distinct outbreaks currently active across the country. This figure is more than double the case count recorded for the entire year of 2025.
Pennsylvania, which has reported the highest number of cases for months, accounted for 1,338 of those infections as of Friday. South Carolina and Utah also reported large clusters, with each state logging more than 500 cases. The CDC noted that official numbers likely undercount the true spread of the disease. Many infected individuals experience symptoms such as rash, fever, and cough that do not immediately prompt a visit to a doctor.
A discrepancy exists between federal and state records regarding fatalities. Pennsylvania authorities reported five measles-associated deaths and are investigating a sixth. The CDC reported only three national deaths and has not identified the location of the third fatality. This ambiguity leaves it unclear whether the federal tally includes a Pennsylvania death or a case from another state.
Health Secretary Robert F. Kennedy Jr. has questioned the accuracy of the federal death count. According to Reuters, he asked senior CDC officials in September to remove a measles death from the official tally after doubting the disease contributed to the outcome. His department is also modifying the vaccine adverse event reporting system, or VAERS. A new proposal will allow doctors to bill for reporting suspected vaccine injuries.
Kennedy has also restructured the agency’s expert advisory boards. He dismissed all 17 sitting members of the panel that evaluates vaccine risks and benefits. He replaced them with ideologically aligned appointees, though a court blocked those appointments in March. During his tenure, Kennedy has made several public claims regarding vaccine safety and composition that contradict extensive medical evidence.
Medical experts note that the measles vaccine remains 97% effective. Without vaccination, one in five infected individuals requires hospitalization, and one to three people per 1,000 die from complications. The virus remains one of the most contagious diseases known to medicine.
