What the Evidence Shows
Multiple independent and authoritative sources report that in 2025, the U.S. Has experienced a significant resurgence of measles cases, surpassing 1,500 confirmed cases. This is the highest annual total since measles was declared eliminated in the year 2000. The Centers for Disease Control and Prevention (CDC) data cited by sources such as NPR, CBS News, and The New York Times consistently show case counts exceeding previous recent years, with figures around or above 1,500 cases by late September 2025. The outbreak is noted to be widespread across many states, with notable clusters such as a large outbreak in West Texas.
Historical comparisons indicate that this is the largest number of cases reported since the early 1990s, approximately 33 years ago. The sources also highlight contributing factors such as vaccine hesitancy and international travel-related importations. While some earlier reports from mid-2025 showed lower counts (around 1,000 to 1,300), the most recent data confirm the surpassing of the 1,500 threshold.
