Measles Exposure At SoCal Theme Park

Los Angeles County health officials said on August 5 that a person with measles visited Universal Studios Hollywood while infectious, creating a potential public exposure at one of Southern California’s busiest tourist sites. The Los Angeles County Department of Public Health said the person was at the park, at 100 Universal City Plaza in Universal City, on Sunday, July 26, from 10 a.m. to 9 p.m. The agency said additional locations where exposures may have occurred are still under investigation. People who were at the park during that 11-hour window were told to check whether they are protected against measles and watch for symptoms through August 16. ### Which visitors are being warned about this exposure? Sunday, July 26, 2026 is the date LA County identified for the public exposure window at Universal Studios Hollywood. The county said anyone who was at the park between 10 a.m. and 9 p.m. that day may have been exposed to the virus. Universal Studios Hollywood, located in Universal City just north of Los Angeles, was the only public site named in the county’s August 5 release. (publichealth.lacounty.gov) The health department said other possible exposure locations are still being examined, but it did not identify them or say when more details might be released. ### How long do exposed visitors need to monitor for symptoms? (publichealth.lacounty.gov) August 16, 2026 is the last day people exposed at the park were told to monitor for measles symptoms, according to the county. Public health officials said measles can develop 7 to 21 days after exposure, and anyone who remains symptom-free for more than 21 days is no longer considered at risk from that exposure. (publichealth.lacounty.gov) Los Angeles County said people who have had measles before or received the recommended measles vaccination are likely protected, but should still watch for symptoms. The county said people who are unvaccinated or do not know their immunization status face higher risk and should monitor closely. ### What did officials say about vaccination and risk? (publichealth.lacounty.gov) Muntu Davis, the Los Angeles County health officer, said in the county release that residents should make sure they are fully protected as cases rise. Davis said the measles-mumps-rubella vaccine is “the safest and most reliable way” to prevent measles and protect families and the community. Los Angeles County’s measles information page says one dose of the MMR vaccine is about 93% effective at preventing measles. (publichealth.lacounty.gov) The same page says measles is an airborne virus and describes it as one of the world’s most contagious diseases, with nine out of 10 unvaccinated people who come into close contact with an infected person becoming infected. Children 12 months and older are considered fully protected after two doses of MMR vaccine, the county said. (publichealth.lacounty.gov) Infants older than 6 months who are traveling internationally or to domestic areas with ongoing outbreaks can receive an early dose, according to the release. ### Is this patient counted in Los Angeles County’s 2026 measles total? Los Angeles County’s measles surveillance page said the county had recorded seven confirmed measles cases in 2026, with counts updated through July 24. (publichealth.lacounty.gov) The county also said public exposure notices can involve people who are not Los Angeles County residents and therefore are not included in the county’s case count. The August 5 release described the patient as “a person who was infectious while visiting LA County,” which indicates the case may involve a visitor rather than a county resident. (publichealth.lacounty.gov) The county did not identify the person, disclose age or residence, or say how the infection was acquired. That is an inference based on the wording of the release, not a separately stated county conclusion. (publichealth.lacounty.gov) ### Where should visitors look for updates or guidance? Los Angeles County directed residents to confirm their immunity and get vaccinated if needed, especially before travel and crowded events. The county’s measles information page includes fact sheets, vaccine guidance and links to press releases for public exposure notices. August 16 is the immediate next date in the case because that is the final day the county gave exposed Universal Studios visitors to watch for symptoms. (publichealth.lacounty.gov) Any additional exposure sites tied to the investigation are expected to be posted by the Los Angeles County Department of Public Health if officials determine there was broader public risk.
