A confirmed measles case spent about 11 hours at Universal Studios Hollywood on July 26, prompting a public-health alert for visitors present between 10:00 a.m. and 9:00 p.m. Officials advised monitoring for symptoms through August 16. Measles is highly contagious and can spread before symptoms appear; two doses of the MMR vaccine are about 97% effective. The U.S. has recorded 2,465 cases in 2026 with outbreaks in 47 states.

Health officials have warned that a person with confirmed measles spent about 11 hours at Universal Studios Hollywood on July 26, potentially exposing many park visitors and employees.
What Happened
According to the Los Angeles Times and the Los Angeles County Department of Public Health, the individual was at the theme park between 10:00 a.m. and 9:00 p.m. on July 26. County officials advised anyone who visited during those hours to monitor themselves for symptoms and remain alert for signs of illness through August 16.
Public Health Advisory: If you were at Universal Studios Hollywood on July 26 from 10:00 a.m. to 9:00 p.m., watch for fever, cough or rash and seek medical advice if symptoms develop. Contact your health provider or local health department for guidance on testing and vaccination.
Why This Matters
Measles is highly contagious. It can spread through the air when an infected person breathes, talks or coughs and can remain infectious on surfaces and in the air for hours. People with measles are contagious from roughly four days before the distinctive rash appears to four days after the rash begins, which makes early detection and timely vaccination critical for preventing onward transmission.
The measles-mumps-rubella (MMR) vaccine is very effective: two doses are about 97% effective at preventing measles infection. Public health officials are urging everyone to confirm their immunity, especially before travel or attending crowded events, and to get vaccinated if they are not up to date.
Current U.S. Situation
The United States has seen a sharp rise in measles cases in recent years. As of last week, the country had recorded 2,465 confirmed measles infections in 2026, surpassing the 2,289 cases reported in 2025. The Centers for Disease Control and Prevention (CDC) reports 38 new outbreaks across the country this year, with several thousand cases spanning 47 states.
Health Risks
The danger is greatest for unvaccinated people and vulnerable groups. The CDC estimates roughly one in five unvaccinated Americans who contract measles are hospitalized. About one in 20 children with measles develop pneumonia, and between one and three of every 1,000 infected children die from respiratory or neurologic complications.
What You Should Do
If you were at the park during the exposure window, monitor for fever, cough, runny nose, red or watery eyes, and rash through August 16. Check your vaccination records — two documented doses of MMR generally indicate immunity. If you are unsure of your status or were exposed and are unvaccinated, contact your healthcare provider promptly; post-exposure vaccination or immune globulin may be recommended in some cases.
Local Status: California has reported several localized outbreaks this year; health officials say three recent localized outbreaks in the state have ended. However, outbreaks continue in multiple states, and vigilance remains important.
