The U.S. measles cases 2026 count has already overtaken last year’s modern record, according to data from the Centers for Disease Control and Prevention. The CDC lists 2,318 confirmed cases this year, above the 2,289 confirmed cases recorded in 2025, which was the highest annual total since 1991.
The timing is the ugly part. The year is only about 58% complete, so the current total is not a final-year comparison. If cases continue to accumulate, 2026 will finish well above the record set one year earlier.
The resurgence follows months of warnings from health professionals and media reports, dating back to early 2025, that measles transmission in the United States was worsening. The disease had been officially declared eradicated in the country, but outbreaks have continued for roughly 19 months, according to the account described by Techdirt.
How many measles cases are in the U.S. in 2026?
The CDC’s current figure is 2,318 confirmed U.S. measles cases for 2026. That is already 29 more than the 2025 total of 2,289 confirmed cases, the prior high-water mark since 1991.
Criticism has focused in part on Robert F. Kennedy Jr., who has been faulted by Techdirt and other critics for leaving vaccination efforts largely to states and for inconsistent public messaging on measles vaccination. Techdirt also cited reports that Kennedy has been disengaged from much of the work at the Department of Health and Human Services.
TIME reported that doctors are now describing the situation in sharper terms. Dr. Paul Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia, told TIME by email that two healthy young girls in West Texas died from measles, calling them the first child measles deaths in the United States in more than 20 years. Offit said he thinks it is fair to call measles “epidemic” in the country and urged people traveling to the United States to make sure their immunizations are current.
Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine, told TIME that measles has returned in practical terms, measured by cases, hospitalizations and two deaths. He also warned that winter and spring surges could worsen in later years, and that pertussis and other childhood infectious diseases could follow the same path.
Why doctors worry about measles beyond the rash
Measles is dangerous on its own, but it also has a nastier feature: immune amnesia. The virus can damage T cells and B cells, the immune cells that help the body remember earlier infections and vaccinations. That can leave people more vulnerable to illnesses their immune systems had previously learned to fight.
That is why a measles rebound is not just a case-count problem. If vaccination rates fall far enough to let measles spread, doctors may also have to deal with the knock-on risk of other preventable diseases returning more often, including pertussis.
The renewed outbreak is also changing research priorities. Wired reported that scientists are beginning to develop drug therapies for measles as case totals rise. For decades, there was little need for that work at scale because vaccination kept the disease rare in the United States.
The CDC’s numbers show that the country has now broken back-to-back measles records in consecutive years. The unresolved question is how much higher the 2026 total climbs before the year ends.
