Opinion: What my colleagues and I will look for as we assess U.S. measles elimination status

In mid-August, colleagues and I will review the evidence and decide whether the U.S. has maintained measles elimination. AdvertisementTo independently certify the CDC’s annual report on measles elimination, the U.S. maintains the United States of America National Verification Committee for the Elimination of Measles, Rubella, and Congenital Rubella Syndrome. In 2025, Canada and the U.S. used partial genome sequencing data to verify their measles elimination status. PAHO was unpersuaded that these were separate introduction events, and as a result Canada lost its measles elimination status in November 2025. He chairs the U.S. committee that reviews the annual CDC measles reports to verify whether the U.S. maintains or loses measles elimination status.
