  • The overall 2026 figures represent the highest number of U.S. cases in ​a single year since a major resurgence of ​the highly contagious disease in the period from 1989 ⁠to 1991, with more than 55,000 infections and 123 ​deaths.
  • Measles-related hospitalizations this year stand at 169 so far with ​zero deaths, compared to 243 hospitalizations and three deaths in 2025.
  • As many as 93% of this year’s cases were in unvaccinated individuals or ​people whose vaccination status was unknown, with the rest ​having received one or two doses of vaccine before being infected, the ‌CDC ⁠said.
  • Infections were documented by the CDC this year in 45 states along with New York City and the District of Columbia. There have been 38 new outbreaks reported in ​2026, compared ​to 48 in ⁠2025.
  • A South Carolina outbreak had sickened nearly 1,000 people over six months after it ​began in October 2025 to become the largest ​single-location ⁠U.S. outbreak since measles was declared eliminated in the United States in 2000.
  • A surge in measles cases during the past ⁠two ​years has coincided with a steady ​slump in MMR immunization rates for children since the start of the COVID-19 ​pandemic.
