Regional Experts Near Ruling on U.S. Measles-Free Status, With Decision Expected Next Week

A panel of independent experts convened by the Pan American Health Organization is meeting behind closed doors in Washington this week to determine whether the United States has lost the measles-elimination status it has held since 2000. The session runs through Friday, Nov. 13, and PAHO Director Jarbas Barbosa will make the final decision, with the result expected to be made public early next week, Reuters reported.

No ruling had been announced as of Thursday. The commission is reviewing all 35 PAHO member states, and Mexico, Guatemala, Peru and Bolivia are also considered at risk, Al Jazeera reported. Canada lost its status in November 2025.

Elimination does not mean a country has no measles. It means endemic spread has been interrupted for at least 12 months, backed by strong surveillance, according to KFF. Cases brought in by travelers do not, on their own, cost a country its standing; the test is whether the same strain kept circulating without a break for a year or more, which investigators check through genetic sequencing. The commission is examining data from 2025 and the first half of 2026.

The trail begins in a small West Texas town, where measles was confirmed in January 2025, ABC News reported, with outbreaks following in Utah, Arizona, South Carolina and Pennsylvania. For months the central question was whether those later outbreaks traced back to Texas. Now the focus is the Arizona-Utah outbreak. Noel Brewer, a University of North Carolina professor who presented the CDC's status report to PAHO's experts, told Reuters that, based on public data, that outbreak began in June 2025, has not ended, and likely meets the threshold.

The CDC has confirmed at least 5,182 cases so far in 2026, more than double the 2,289 recorded in all of 2025, ABC reported. Cases have turned up in 47 states, the worst year since 1991, Healio reported. Eleven people have died of measles since early 2025, most of them unvaccinated or too young for the vaccine. This year's deaths include six in Pennsylvania, beginning with two unvaccinated infants, plus a child in New York and an infant in Wisconsin.

The Department of Health and Human Services rejects claims that its current leadership is to blame. Senior press secretary Emily Hilliard told Healio that such arguments ignore vaccination gaps that predate the administration, citing COVID-era disruptions and lost public trust. She said Secretary Robert F. Kennedy Jr. and CDC Director Erica Schwartz have mounted an aggressive response, that the CDC has provided roughly $100 million in added funding, and that the department continues to recommend the MMR vaccine as the most effective protection.

The record supports part of that argument. Two-dose MMR coverage among kindergartners had already slipped from 95.2 percent in the 2019-2020 school year to 92.5 percent in 2024-2025, according to KFF. It stood at 92.4 percent heading into the 2025-2026 school year, below the 95 percent experts say is needed to prevent outbreaks.

Schwartz told Reuters the CDC works closely with states, focusing on communities where immunization rates have trended lower for decades, and that a loss of status would not change that work: "we're going to be doing the same exact thing that we've been doing today". She called the MMR vaccine the number one way to prevent measles.

Critics point elsewhere. Reuters noted that Kennedy has questioned vaccine safety for years, and some experts say his actions have deepened hesitancy. Dr. Paul Offit of Children's Hospital of Philadelphia told Healio he faults the administration for feeding vaccine fears.

Many physicians say the label matters less than the spread. Offit and Dr. Peter Hotez of Baylor College of Medicine told ABC that losing the status would largely be a formality, with Hotez stressing how widely the virus is moving. "At best, losing the elimination status would be a call to arms," Offit said. Matt Ferrari of Pennsylvania State University called the likely outcome "a disappointment, not a shock," Al Jazeera reported.

A loss would carry no immediate penalties but would add strain on health departments, Al Jazeera reported. The status can be won back: Brazil lost it in 2019 and regained it in 2024 after a targeted vaccination campaign.

The CDC's guidance is plain. One dose of MMR vaccine is 93 percent effective against measles, and two doses are 97 percent effective. Children should get the first dose at 12 to 15 months and the second at 4 to 6 years, and infants 6 to 11 months old should get an early dose before international travel. Adults without evidence of immunity need at least one dose.

Whatever the commission decides next week, the duty in front of American families has not changed. The CDC director, the HHS press office and the pediatricians agree on the central point: the vaccine works. Babies too young for the shot depend on the protection of the people around them, and caring for the most vulnerable is a calling as old as Scripture. Parents unsure of their children's records, or their own, would do well to call the family doctor.
