Overview
- The CDC told state and local agencies that more measles cases are likely during the spring and summer travel season.
- Officials directed rapid 24-hour reporting to the CDC, hospital reporting, contact tracing for exposed people, active surveillance, and quick lab confirmation.
- U.S. health data show 1,792 confirmed cases this year in 36 states, with about 92% in people who are unvaccinated or whose status is unknown.
- Orange County, California, confirmed an infant case linked to international travel and alerted people who may have been exposed in clinics and other locations.
- Falling kindergarten MMR coverage to 92.5% and a pending review of the nation’s measles elimination status highlight the risk of sustained spread.
