Summary
2,030 confirmed measles cases have been recorded in 2026 across 39 states and Washington, D.C., pushing the U.S. above 2,000 cases for a second straight year, CDC data updated Friday showed.
92% of cases are in people who were unvaccinated or whose vaccination status was unknown, while 4% were in people with one MMR dose and 4% in those with the recommended two doses.
Children and teenagers 19 and younger account for most infections, and only 10 cases this year were reported among international travelers.
Last year ended with 2,288 confirmed cases, and before 2025 the U.S. had not exceeded 2,000 measles cases in a year since 1992.
