The CDC reported 1,671 confirmed measles cases in the United States as of April 2, 2026, spread across 33 states and international visitors. [1] Ninety-four percent of those cases -- 1,570 of 1,671 -- are linked to one of the 17 active outbreaks. The unvaccinated or vaccination-unknown population accounts for the overwhelming majority of infections. [1]

The case count puts 2026 on pace to exceed 2025's 2,267 cases, itself the highest annual total in more than three decades. Ninety-six new cases were added in the week ending April 2, with 73 in Utah alone. [2] South Carolina and Utah remain the largest active outbreak sites. Hospitalizations are running at 5 percent of cases this year, compared to 11 percent in 2025 -- a difference that may reflect patient demographics or case-finding patterns rather than reduced severity. [2]

The structural vulnerability is documented. Kindergarten vaccination coverage has fallen to 92.5 percent nationally for the 2024-2025 school year, below the 95 percent threshold that produces community immunity. That gap leaves approximately 286,000 kindergarteners at risk in any given outbreak year. [1]

Measles was declared eliminated in the United States in 2000. Elimination requires sustained vaccination rates above 95 percent and rapid outbreak containment. Neither condition currently holds.
