Los Angeles County Department of Public Health says people who were at Universal Studios Hollywood on Sunday, July 26 may have been exposed to measles. The department’s notice indicates that measles transmission is possible from an infected person while they are at a location, so visitors and staff present during that time are advised to check their vaccination status and follow public health guidance. Additional reporting describes the issue as tied to a measles-infected visitor who spent much of the day at the park, prompting the warning for attendees. Health officials emphasize that the risk depends on whether individuals were in areas where an infected person was present and whether they are immune to measles through prior vaccination or infection. The county is encouraging anyone potentially exposed to monitor symptoms and seek medical advice, particularly if they are not fully vaccinated or are in a higher-risk group. Officials also continue efforts to identify and notify those who may have been affected.
