CDC Health Advisory:
Increase in Global and Domestic Measles Cases and Outbreaks: Ensure Children in the United States and Those Traveling Internationally 6 Months and Older are Current on MMR Vaccination
March 18, 2024
The Centers for Disease Control and Prevention (CDC) is notifying clinicians about an increase in global and U.S. measles cases and asking clinicians to ensure that children and international travelers are up to date on their MMR vaccinations. There have already been 58 confirmed U.S. cases of measles reported nationwide in 2024. Four cases have been reported in California including one in Los Angeles County, all of whom traveled overseas. There are ongoing outbreaks occurring in many popular travel destinations in Europe and Asia.
With spring break approaching, clinicians should make sure that prior to any international travel, all individuals 6 months and older are protected against measles regardless of their destination. Additionally, consider measles in the differential diagnosis for anyone with fever and rash who has recently traveled abroad or domestically through an international airport. Delays in identifying and isolating measles cases in health care settings can result in exposures to hundreds of additional contacts.
Suspect measles cases should be reported to Public Health immediately, while the patient is still at the facility. Public Health will guide you through collection of specimens for testing (throat swab and urine samples for PCR and blood sample for serology) and management of the patient under investigation as well as asymptomatic contacts of a suspected or confirmed case.
