The number of recorded measles cases in the U.S. during 2025 has exceeded 2,000 for the first time in more than 30 years, according to data from the Centers for Disease Control and Prevention.
Why it matters: This year's surge in cases and prolonged outbreaks could cause the U.S. to lose its globally recognized measles "elimination status" for the first time in decades by the end of January 2026.
