CDC logs 4,588 measles cases

The United States has recorded 4,588 cases of measles in 2026 as of Friday, a total that is more than double the tally for the previous year. The Centers for Disease Control and Prevention announced that 178 new infections were identified during the week ending October 16. These cases are spread across at least 43 active outbreaks.

Pennsylvania remains the hardest-hit state, with officials reporting 1,338 local cases on the same date. South Carolina and Utah also face severe strains, with each region reporting more than 500 cases. Experts note that official numbers likely undercount the disease because common symptoms like fever and cough often do not prompt immediate medical visits. The virus is highly contagious, and the vaccine is 97% effective at preventing infection.

A discrepancy exists between state and federal mortality data. Pennsylvania authorities have confirmed five deaths linked to the illness and are investigating a sixth case. The CDC has reported three national deaths but has not specified the location of the third fatality. This ambiguity leaves it unclear whether the federal count includes a Pennsylvania death or one from another state.

Robert F. Kennedy Jr., the Health and Human Services secretary, reportedly asked senior CDC officials in September to remove one death from the official tally. He questioned whether measles contributed to that specific death, according to Reuters. This move has drawn criticism from experts who cite a lack of transparency in the agency’s reporting.

HHS announced changes to the vaccine adverse event reporting system, or VAERS, earlier this week. The proposal will allow doctors to bill for reporting suspected vaccine injuries. While the system helps researchers track safety issues, it has also been a focal point for anti-vaccine activism. Before Kennedy’s appointment, an expert panel evaluated vaccine changes to ensure benefits outweighed risks. Kennedy dismissed the 17 sitting members and replaced them with ideologically aligned candidates, a move a court blocked in March.

Kennedy has made several public statements regarding vaccines that clinicians described as misleading. He claimed that the measles, mumps, and rubella vaccine contains aborted fetal debris and that vitamin A and cod liver oil may help children with measles. He also directed the CDC to remove website claims stating that vaccines do not cause autism, despite extensive evidence to the contrary.

The next step involves the implementation of the new VAERS billing rules and continued monitoring of the 43 outbreaks. State health departments will continue to report case data to the CDC as the season progresses.
