Overview
- A visitor who was infectious at Universal Studios Hollywood on July 26 spent about 11 hours in the park from 10 a.m. to 9 p.m., and anyone there during that window may have been exposed.
- Los Angeles and Ventura county health officials are tracing contacts, investigating other possible exposure sites, and asking exposed people to monitor for symptoms through Aug. 16.
- Officials say people with two documented MMR doses or prior measles are likely protected, while unvaccinated or unknown‑status people face higher risk and should check records.
- Ventura County confirmed the case was linked to international travel and said no park‑linked secondary infections have been publicly confirmed as investigations continue.
- Public‑health agencies note this warning comes as a nationwide surge continues with more than 2,300 cases in 2026, an outcome that could drive more vaccination checks and clinic calls for exposed or high‑risk people.
