Measles Data: Federal and State Disagreements

The Centers for Disease Control and Prevention reported 178 new measles cases in the United States this week. This brings the 2026 national total to 4,588, a figure that more than doubles the count from 2025. The agency said at least 43 active outbreaks are currently underway across the country.

Pennsylvania continues to bear the heaviest burden, with state officials recording 1,338 cases as of Friday. South Carolina and Utah also report large clusters, with each state logging more than 500 cases. Despite these high numbers, experts argue the official data likely undercounts the true spread of the disease.

Measles is highly contagious, and symptoms like rash, fever, and cough often delay medical visits. For unvaccinated individuals, the infection leads to hospitalization in one in five cases and death in one to three out of every 1,000 patients. The vaccine remains 97% effective, though its safety record has become a central point of political debate.

A specific conflict has emerged over how deaths are tallied. Pennsylvania authorities have reported five deaths linked to measles and are investigating a sixth. The CDC has only confirmed three national deaths and has not specified the location of the third case. This omission leaves it unclear if federal records include the Pennsylvania fatalities.

Health and Human Services Secretary Robert F. Kennedy Jr. reportedly asked senior CDC officials in September to remove one measles death from the official count. He questioned whether the disease contributed to that specific death, according to Reuters. This action has fueled criticism that the agency lacks transparency in its reporting.

The department is also restructuring how vaccine safety is monitored. A new proposal allows physicians to bill for reporting suspected vaccine injuries through the Vaccine Adverse Event Reporting System. While researchers use this system to track rare issues, it has also drawn scrutiny from groups questioning vaccine safety.

Kennedy replaced all 17 members of the expert panel that previously evaluated vaccine risks and benefits. A court blocked the appointment of his replacements in March. During his tenure, he has also claimed that children receive over 90 vaccine doses and that the measles vaccine contains aborted fetal debris. Leading physicians have described his suggestion that vitamin A and cod liver oil can treat measles as misleading.
