4,588 Measles Cases Reported as Officials Disagree on Death Toll

Measles is spreading faster than federal officials can count it, with the Centers for Disease Control and Prevention reporting 4,588 cases in 2026 as of Friday. That is more than double the tally recorded for 2025. The agency added 178 new infections this week, and outbreaks are active in at least 43 locations. Pennsylvania reports 1,338 cases, the highest state total, while South Carolina and Utah each exceed 500.

The counts for deaths do not match. Pennsylvania state authorities report five measles-associated deaths and are investigating a sixth. The CDC reports three deaths nationally and has not disclosed where the third occurred. Reuters reported that Health Secretary Robert F. Kennedy Jr. asked senior CDC officials in September to remove a measles death from the tally after he questioned whether the illness contributed to it.

Kennedy has also changed how the federal government tracks vaccine injuries. The Department of Health and Human Services proposed rules this week that would allow doctors to bill for reporting suspected vaccine injuries. The proposal affects the Vaccine Adverse Event Reporting System, known as VAERS, which researchers use to monitor rare safety issues. Anti-vaccine activists have also cited the system to make claims about vaccine risks. Kennedy dismissed all 17 members of the expert panel that weighed individual vaccine changes for risks and benefits. A court blocked his replacements in March.

Measles spreads easily. The CDC states that one in five unvaccinated people who catch the virus ends up in the hospital, and one to three people in 1,000 die from related complications. The vaccine is 97% effective at preventing infection. Reported side effects include soreness at the injection site and low-grade fever.

Measles symptoms include rash, runny nose, fever and cough. Because those signs are common, some people who carry the virus do not seek care right away, so official tallies fall short of the actual spread.

Kennedy has said children receive more than 90 vaccine doses and linked vaccines to autism, a connection extensive evidence contradicts. He directed the CDC to remove statements from its website saying vaccines do not cause autism. He also said the measles, mumps and rubella vaccine contains 'aborted fetal debris' and suggested vitamin A and cod liver oil may help children with measles. Leading physicians called that last claim misleading.
