Measles cases in the United States have reached 4,410 this year, representing an 8% increase over the past week alone. This single-week surge of 330 cases already exceeds the entire 2024 measles total of 285 cases. The outbreak has spawned 42 new outbreaks across the country, with 96% of confirmed cases occurring in people who were unvaccinated or had unknown vaccination status. Public health experts believe the actual number of infections is substantially higher than reported figures due to underreporting of milder cases treated at home rather than in medical settings.
Pennsylvania has been particularly hard hit, reporting 1,260 confirmed cases and six deaths. Health officials estimate the true number of infections in the state could exceed 6,000 based on historical measles mortality rates. The CDC has deployed epidemiologists to help contain multiple outbreaks in Pennsylvania counties. Other states experiencing significant measles activity include Kentucky with 170 cases, New York with 126 cases and a declared statewide health emergency, and Ohio with 252 cases.
