CDC Records 4,588 Measles Cases as Pennsylvania Death Data Diverges

The Centers for Disease Control and Prevention reported 4,588 measles cases across the United States on Friday. This total includes 178 new cases identified during the current week. The figure represents more than double the number of cases recorded in 2025. At least 43 distinct outbreaks are currently active in the country.

Pennsylvania accounts for the largest share of the disease burden. State health officials logged 1,338 cases as of the same Friday deadline. South Carolina and Utah follow, with each state reporting more than 500 confirmed infections. Medical experts note that official tallies likely undercount the true prevalence of the virus. The rash, fever, and cough associated with measles often fail to prompt immediate medical visits, allowing the highly contagious disease to spread undetected.

A discrepancy exists between state and federal records regarding fatalities. Pennsylvania authorities have reported five confirmed measles-related deaths and are investigating a sixth. The CDC has confirmed only three deaths nationwide. The agency has not specified the location of the third death, leaving uncertainty about whether it is included in the Pennsylvania state count.

Health Secretary Robert F. Kennedy Jr. reportedly questioned the validity of one death in September. According to Reuters, Kennedy asked senior CDC officials to remove that case from the official tally after he determined the disease did not contribute to the patient's death. This action adds to a wave of criticism regarding the agency's transparency on mortality data.

The HHS also announced changes to the vaccine adverse event reporting system, known as VAERS. The proposal allows physicians to bill for reporting suspected vaccine injuries. While researchers use VAERS to track rare safety issues, the system has frequently been cited by anti-vaccine activists to make unsupported safety claims.

Kennedy has restructured the oversight bodies responsible for vaccine safety. He dismissed all 17 members of the expert panel that previously evaluated vaccine benefits and risks. He replaced them with individuals who share his ideological views. A court blocked those appointments in March, though Kennedy has continued to push changes in the interim.

During his tenure, the Secretary has made several public claims about vaccine safety and composition. He stated that children receive more than 90 vaccine doses and suggested that vaccines cause autism. He also directed the CDC to remove statements from its website claiming that vaccines do not cause autism. Kennedy further asserted that the measles, mumps, and rubella vaccine contains aborted fetal debris and that vitamin A and cod liver oil can help treat measles in children.
