Measles Cases in U.S. Reach 1,136 in Early 2026, Indicating Potential Record Surge
The United States has reported 1,136 confirmed measles cases as of February 26, 2026, raising concerns about a potential record surge in infections this year.
As of February 26, 2026, the United States has reported 1,136 confirmed measles cases, according to the Centers for Disease Control and Prevention (CDC). This figure represents nearly half of the total cases reported in 2025, which saw 2,281 cases—the highest annual count since 1991.
The majority of the 2026 cases have been reported in 28 states, including Arizona, California, Florida, and New York. Notably, 90% of these cases are associated with 10 new outbreaks identified this year. Health experts express concern over the rapid increase in infections, emphasizing the importance of vaccination. The measles-mumps-rubella (MMR) vaccine is 97% effective when both doses are administered.
Measles is a highly contagious viral infection that can lead to severe complications, including pneumonia and encephalitis. The CDC reports that approximately 12% of measles cases in 2025 required hospitalization, and there were three confirmed deaths. The current surge underscores the need for maintaining high vaccination coverage to prevent further spread of the disease.
