Measles outbreaks worsen in South Carolina, Arizona and Utah
Measles transmission has intensified in multiple states, with large outbreaks reported in South Carolina, Arizona and Utah as national case counts approach historic highs last seen decades ago, driven largely by pockets of low vaccination coverage and international importations. This surge has prompted school exposures, quarantines and increased hospitalizations as health departments trace contacts and update exposure locations.
Public health context and response
Local officials are confirming new cases and recommending MMR vaccination for susceptible people while urging employers and schools to support quarantine orders; many cases involve unvaccinated children and adolescents, and the virus can linger in the air for up to two hours after an infectious person leaves a room. Enhanced surveillance, community outreach and rapid vaccination clinics are being used to contain spread and protect vulnerable populations.
