U.S. measles cases hit highest level in 33 years, CDC reports
The U.S. has hit an unwelcome milestone in measles cases this year. The CDC is reporting 1,288 cases across the country. The disease was declared eliminated 25 years ago.
www.npr.orgHere are the latest available highlights on measles as of 2025–2026:
- United States outbreak activity: In 2025, the U.S. experienced a significant measles outbreak with hundreds to over a thousand cases reported across multiple states, driven largely by unvaccinated or unknown vaccination status individuals. Hospitalization rates were notable, and several deaths were reported during the year.[1][2][4]
- Global context: WHO and CDC assessments in 2025 highlighted measles as a continuing public health concern, with outbreaks outside the U.S. and increasing numbers of cases in some regions, despite the disease having been eliminated in the United States in 2000. The global data for 2023–2024 showed substantial measles activity in many countries and emphasized vaccination coverage gaps.[4][6]
- US vaccination and public health response: Health authorities continued to promote MMR vaccination as the primary preventive measure, with responses including outbreak control efforts, postexposure prophylaxis in affected communities, and efforts to improve vaccination coverage to prevent further spread.[2][4]
- Notable developments: By mid-2025 and into late 2025, reports indicated continued transmission in several states, ongoing investigations into outbreak sources, and occasional fatalities linked to measles infections, underscoring the importance of vaccination and rapid public health action.[3][2][4]
If you’d like, I can tailor a brief regional brief (e.g., for Brazil or Ceará) and provide sources with direct links. I can also summarize vaccination recommendations and outbreak indicators for your area. Please tell me which region or aspect you want more detail on.
