The United States is facing a major public health challenge as the number of Measles Resurgence in 2025 edges dangerously close to a modern-day record. According to the Centers for Disease Control and Prevention (CDC), an additional 40 cases were reported last week, bringing the national total to 1,267. This places the U.S. within just eight cases of surpassing the 2019 peak of 1,274, the highest annual count since the disease was declared eliminated in 2000. At the heart of this surge are 27 confirmed outbreaks defined as three or more epidemiologically linked cases, more than doubling the total seen in 2024. Health officials note that while a major outbreak in West Texas is winding down, smaller clusters and travel-related infections continue to sustain the virus’s spread across the country. The measles resurgence is also part of a broader regional pattern. Canada and Mexico are experiencing parallel outbreaks, with under-vaccinated populations such as Mennonite communities serving as hotspots for transmission.
