The United States has recorded 2,371 measles cases in 2026 as of the latest tally, surpassing the 2,289 cases logged in all of 2025 and marking the highest national count since 1991. [1] The 2026 figure exceeds the full prior year by 82 cases, with months still left on the calendar. [1]
Federal data tie the surge to sustained community spread. There are 37 separate outbreaks, and 94 percent of the year's cases are outbreak-associated rather than isolated, meaning the overwhelming majority trace to clusters rather than scattered one-off infections. [1]
No deaths have been reported in 2026. [1]
The 1991 benchmark is the salient one. Reaching a level not seen in more than three decades before the year is even out shows how much routine transmission has resumed, and the burden falls hardest on the outbreak communities where the 37 clusters are concentrated. [1]
