Key points
  • has lost its status as a country where measles is eliminated, according to researchers with direct knowledge of the deliberations at the Pan American Health Organization.
  • The measles elimination status hinges on whether the same strain of measles stays in circulation for 12 months or longer without a break.
  • While overall measles vaccination rates remain relatively high, public health officials say they have to remain above 95% to maintain herd immunity.

The Pan American Health Organization has reportedly stripped the US of its measles-elimination status after 26 years, as the country battles its worst outbreaks in more than three decades.

Canada and the United Kingdom have both lost their measles elimination status over the past year.

Additional details
  • While most measles cases aren't severe, they can have long-lasting effects because of the way the virus can suppress the body's immune responses, leaving people more susceptible to other infections.
  • The big picture: The Pan American Health Organization concluded there has been sustained transmission of the highly contagious virus for longer than 12 months, bringing the U.S.
  • Driving the news: An expert panel convened by the Pan American Health Organization made the widely expected decision following a three-day meeting in Washington, D.C.
  • "It is unthinkable that people in the United States should be dying from measles in 2026," the Infectious Diseases Society said in comments prior to the decision.
  • How it works: Experts rely on disease tracking by local health departments and genetic sequencing, and can also factor vaccination rates and surveillance efforts.
