U.S. measles tally reaches 416 cases in 2026 as states track exposures and urge vaccination

U.S. health officials are monitoring a growing measles caseload at the start of 2026. The CDC reported that, as of January 22, 2026, there were 416 confirmed measles cases reported in the United States in 2026, spanning multiple jurisdictions, with most cases associated with ongoing outbreaks that began in 2025.

State health agencies continue to release exposure alerts and updates that reflect how quickly measles can spread when immunity gaps exist. In North Carolina, the Department of Health and Human Services announced on January 6, 2026 that additional measles cases were confirmed in three siblings in Buncombe County, with the department tracing the likely link to travel to South Carolina’s outbreak area. The advisory also warned of a potential exposure window at Mission Hospital’s emergency department waiting room in Asheville on January 4, 2026.

In South Carolina, the Department of Public Health has continued to report rising case counts tied to an outbreak centered around Spartanburg County. The agency’s updates have stressed measles’ high contagiousness—including that people can spread it before realizing they are infected—and have urged residents to use vaccination as the primary protection tool.

Public health messaging in this kind of outbreak focuses on two practical actions: confirming vaccination status and responding rapidly to potential exposure. Health departments typically ask exposed individuals to monitor for symptoms, follow quarantine guidance when applicable, and contact clinicians before arriving in person—so clinics can reduce the risk of onward transmission in waiting rooms and emergency departments.

The early-2026 case totals highlight how outbreaks can persist across calendar years and across state lines. Officials say the best way to prevent future surges is to raise community immunity through timely MMR vaccination and to quickly identify exposure sites and contacts when cases appear.
