What happened

The Pan American Health Organization has revoked the United States' measles-elimination status, which the country held for 26 years, after finding the virus kept spreading continuously for more than a year. Confirmed cases this year have reached 5,412, more than double the 2025 total, and measles deaths have risen to 10.

Why it matters

The designation is largely symbolic, but it means measles is once again spreading widely across communities in the United States. Health experts say it is more than a symbolic milestone.
