More than 2,100 measles cases have been confirmed in the United States this year, and the summer travel season is about to begin. Federal health officials have issued a direct warning: unless communities and travelers act, the number will keep rising.
According to the CDC, as of June 18, 2026, 2,104 confirmed measles cases were reported in 41 U.S. jurisdictions, with 30 active outbreaks and 93 percent of cases linked to those outbreaks. The country has already nearly matched its 2025 full-year total — a year that saw 2,288 cases and three deaths — while still months from autumn.
