The United States has, according to researchers close to deliberations at the Pan American Health Organization, lost the measles elimination status it earned roughly a quarter century ago, because the virus has again taken up regular circulation within its borders. The loss did not arrive suddenly; it followed a Utah outbreak that outlasted its one-year window in June, and a longer slide in childhood vaccination that began with the pandemic.

U.S. Loses Measles Elimination Status as Outbreaks Persist and Federal Response Draws Scrutiny
At least 13 measles-associated deaths have been reported in the U.S., including infants, and over 830 people hospitalized in the past two years.
The United States has, according to researchers close to deliberations at the Pan American Health Organization, lost the measles elimination status it earned roughly a quarter century ago, because the virus has again taken up regular circulation within its borders. The loss did not arrive suddenly; it followed a Utah outbreak that outlasted its one-year window in June, and a longer slide in childhood vaccination that began with the pandemic. The meaning of the moment is contested, with officials pointing to gaps that predate them and critics pointing to cuts, muted reporting, and a response that many found quieter than the danger required. What remains is a question of whether a nation that once showed what coordinated immunity could achieve can recover it.
The United States has lost its measles elimination status, according to researchers with direct knowledge of deliberations at the Pan American Health Organization. They told KFF Health News that the virus has re-established regular transmission, undoing a achievement secured about 25 years ago. A public announcement had been planned for Nov. 17.
Elimination depends on outbreaks dying out within a year, and that is no longer happening. PAHO based its assessment on analyses from the CDC and an independent group of measles experts. Anne Schuchat, a former CDC deputy director, called it "a very sad moment," pointing to the harm the disease brings, from high fever and missed school to degenerative nerve disease and death.
The toll is measurable: more than 830 hospitalized and over 8,000 sickened in two years, with 13 deaths, including infants. Two MMR doses prevent about 97% of infections, and when roughly 95% of a community is immunized, outbreaks fade. HHS attributes the resurgence to gaps opened before this administration, while many scientists fault federal cuts, misinformation, and weakened outbreak response. Former CDC director Susan Monarez told Congress she was fired for refusing to preapprove vaccine recommendation changes without evidence review.
Past responses looked different. Patsy Stinchfield, a Minnesota nurse during the 1989 to 1991 surge, remembers a government that saw the urgency then. The 2025 West Texas outbreak, by contrast, grew into the largest since 1992 and killed at least 16, yet drew no congressional hearing and few detailed federal reports. CDC staff say political appointees have delayed or blocked publications, a charge HHS calls false.
What happens next depends on whether the Nov. 17 announcement confirms the finding, and whether federal agencies treat outbreaks as the exceptions they once were.
The United States has lost its status as a country that has eliminated measles, according to researchers with direct knowledge of the deliberations at the Pan American Health Organization. They told KFF Health News that PAHO reached its conclusion this week: the virus has re-established regular transmission in the country. A public announcement had been planned for Nov. 17. The finding undoes a public health achievement secured about 25 years ago.
Elimination depends on sporadic outbreaks ending within a year, and that is no longer happening. Researchers had expected this outcome since an outbreak in Utah passed the one-year mark in June. PAHO, which oversees health in the Americas and works with the World Health Organization, based its assessment on two analyses: one from the CDC and one from an independent group of measles experts. Anne Schuchat, an epidemiologist and former CDC deputy director who was not involved in the decision, called it "a very sad moment." She pointed to the range of harm measles causes, from high fever and missed work and school to progressive degenerative nerve disease and death.
The toll is measurable. Over the past two years, more than 830 people have been hospitalized and more than 8,000 sickened. Johns Hopkins University researchers estimate the outbreaks have cost roughly $125 million in medical care, public health response, and lost productivity. States have reported 13 measles-associated deaths, including a 7-month-old in New York and infants in Pennsylvania and Wisconsin in recent months. Babies typically are not vaccinated before age one. Two doses of the MMR vaccine prevent about 97% of infections, and when about 95% of a community is immunized, outbreaks fizzle out.
The administration and its critics offer different explanations. HHS spokesperson Emily Hilliard attributed the resurgence to vaccination gaps that opened years before this administration, and childhood vaccination rates have indeed fallen steadily since the COVID pandemic began. Many scientists also fault the Trump administration for spreading misinformation and weakening outbreak response. It cut millions from state children's immunization programs and ended funding for research on vaccine hesitancy. Susan Monarez, the CDC director Health Secretary Robert F. Kennedy Jr. fired in August 2025, told Congress she was dismissed for refusing to preapprove changes to vaccine recommendations without reviewing the evidence. White House spokesperson Allison Schuster said the President and Secretary have repeatedly encouraged vaccination, coordinated with states, and helped deploy doses.
Past responses looked different. Patsy Stinchfield, who now leads the Measles Collaborative, was a pediatric nurse in Minnesota during the 1989-1991 surge. Her hospital had a ward devoted to measles, and two children died. Back then, she said, the government saw the urgency. A CDC committee recommended a second MMR dose, and the Vaccines for Children program was created after analyses showed cost kept children unvaccinated. By 2000, measles was declared eliminated. After the 2015 Disney-linked outbreak of about 125 cases, Congress summoned Schuchat to testify. Surgeon General Vivek Murthy appeared with Elmo, and California and Vermont tightened requirements. In 2019, Alex Azar and Robert Redfield held a press conference on on-time vaccination, and CDC's MMWR published detailed reports within weeks of data collection.
The 2025 West Texas outbreak met a quieter response. It became the largest since 1992 within seven months, spread to Mexico and at least three other states, sickened more than 4,500 people, and killed at least 16. Kennedy falsely claimed on Fox News that the vaccines cause "deaths every year." Congress held no hearing, funds arrived after the emergency had subsided, and apart from an annual update the MMWR published no outbreak reports that year. "The dog didn't bark," said Dorit Reiss of UC Law San Francisco.
CDC officials, speaking anonymously for fear of retaliation, told KFF Health News that political appointees have delayed or blocked MMWR articles. One said there is a deliberate effort to downplay vaccine-preventable diseases. Hilliard called the suggestion of suppression false, said Kennedy and the CDC have provided about $100 million in additional outbreak funding, and said report timing varies with analysis and review. A few Texas reports appeared more than a year after data collection; one covered 60 hospitalized patients, two of whom needed ventilators. No detailed reports have appeared on outbreaks in South Carolina, Utah, and Pennsylvania. The CDC dashboard counts four fewer deaths than states have reported, and the agency's autism webpage was altered at Kennedy's direction.
What to watch is whether PAHO's Nov. 17 announcement confirms the finding, and how federal agencies respond to outbreaks that are no longer exceptions.
