Measles Cases Surge in U.S., Canada, and UK

Measles cases have surged in 2025, with over 1,000 infections reported across the United States, surpassing last year's total and prompting public health alerts. Recent confirmed cases in California, Virginia, Georgia, and South Dakota are linked to international travel and community settings such as hospitals and schools. Utah is monitoring possible exposures following an unvaccinated, infectious visitor, though no cases have been confirmed in the state. Outbreaks are also worsening in Canada and the UK, exacerbated by a post-pandemic decline in vaccination rates. Health authorities stress the importance of the MMR vaccine, warning that rates below 95% are fueling outbreaks and that unvaccinated individuals, especially children, are at highest risk. Officials urge symptomatic individuals or those with possible exposure to consult medical providers before seeking in-person care to prevent further spread.
