New CDC data reveals a major measles outbreak in the United States, with over 2,000 confirmed cases, the highest number in more than three decades. Health officials link the surge to declining vaccination rates and rising vaccine hesitancy, fueled by misinformation.
Measles, a highly contagious viral disease, begins with flu-like symptoms and a red rash. As of December 23, 2,012 cases were reported nationwide—levels not seen since 1992. In 2025 alone, 50 outbreaks were recorded, more than triple last year’s total, with a major hotspot in South Carolina.
CDC data shows 93% of patients were unvaccinated or had unknown vaccination status, and 11% required hospitalization, mostly children and teens. Experts warn the U.S. risks losing its measles-eliminated status, as global cases also hit a 25-year high.
The CDC continues to urge parents to follow the MMR vaccine schedule, which provides up to 97% protection with two doses, calling vaccination the most effective way to stop the outbreak.
