Recent outbreaks of measles in the United States are driving up case counts and threatening the country’s elimination status, especially as vaccination rates among children lag.
Cases have now broken a record for two years in a row. Just over halfway through 2026, the country has recorded more cases than in any other year since the disease was declared eliminated in the US a quarter-century ago. It’s the worst year for measles cases since 1991.
Three people died in 2025, the first reported measles deaths in the United States since 2015.
CNN is monitoring these cases and updating this page each week as new national data is released by the US Centers for Disease Control and Prevention.
A large outbreak in West Texas accounted for at least a third of all national cases in 2025, with multiple states reporting cases with links back to Texas. State officials declared that outbreak over in mid-August, but other outbreaks continue to grow.
