Surging Measles Crisis Threatens U.S. Elimination Status
As of July 16, 2026, 2,260 confirmed measles cases were reported in the United States in 2026. There have been 34 new outbreaks reported in 2026, and 93% of confirmed cases (2,108 of 2,260) are outbreak-associated (741 from outbreaks starting in 2026 and 1,367 from outbreaks that started in 2025).
Public Health Concerns and Response
U.S. News tracks the 2026 measles surge as officials prepare to review the nation's elimination status following 32 new outbreaks this year. The rapid escalation marks a significant public health challenge, as measles is a highly contagious viral disease that can cause serious complications including pneumonia, encephalitis, and death.
Investigation and Contact Tracing
State, local, tribal, and territorial health departments lead measles case and outbreak investigations. States notify CDC of measles cases reported in their jurisdictions and may request appropriate assistance from CDC to help with their investigations. Each confirmed outbreak triggers comprehensive contact tracing efforts to identify and monitor exposed individuals who may develop symptoms within the typical 10-14 day incubation period.
What Comes Next
Health officials continue to emphasize vaccination as the most effective prevention strategy. The CDC remains focused on containing outbreak clusters and preventing further transmission in vulnerable communities, particularly among unvaccinated and under-vaccinated populations.
