Summary
More than 2,700 U.S. measles cases have been confirmed in 2026, already topping all of 2025, which was itself the worst year since 1991.
CDC guidance says exposed people without proof of immunity should act fast: an MMR shot within 72 hours can still blunt infection, while immune globulin can help certain high-risk patients for up to six days.
Adults vaccinated in 1963-67 may need revaccination because some received a discontinued killed vaccine, and many others got only the single dose used before 1989; an IgG blood test can confirm immunity.
Suspected cases should not walk into ERs or clinics unannounced because measles is airborne; patients should call ahead so providers can isolate them and alert local health departments for testing and contact tracing.
The report argues the resurgence is also a healthcare-navigation problem: after decades of rare exposures, many patients and health systems still lack a clear playbook for where to go and who coordinates care.
