U.S. Measles Cases Top 1,100, Threatening Elimination Status
CDC reported 1,136 measles cases as of February 26, 2026, raising the risk the U.S. could lose measles elimination status ahead of an April review.
Overview
The CDC reported 1,136 confirmed measles infections in the United States as of February 26, 2026.
That total is already roughly half of the 2,281 confirmed cases reported in 2025, reflecting accelerated spread and increased local transmission.
Public health experts said declining vaccination rates are driving the surge and warned local chains of transmission could erase the country's measles-free status if they persist beyond 12 months.
About 96% of recent U.S. measles cases have been among people not fully vaccinated, and more than 80% have been among children and teens, public health data show.
The Pan American Health Organization will review the United States' measles elimination status in April.
