The U.S. is experiencing a significant measles outbreak with 800 confirmed cases across 24 states, a near tripling of 2024's numbers. Eighty-eight new cases were reported last week, and two deaths have been confirmed. Six states have major outbreaks. The CDC notes that 96% of cases involve unvaccinated individuals and that the actual number is likely higher. The outbreak threatens the U.S.'s measles elimination status achieved in 2000. The MMR vaccine is highly effective in preventing infection.
