Public health officials warned Saturday of possible measles exposure at Los Angeles International Airport, the Disneyland Resort and other Southern California locations tied to an international traveler.

An airplane passenger who was infected with measles passed through LAX’s Tom Bradley International Terminal on Jan. 26 after arriving on Viva Aerobus Flight 518, the Los Angeles County Department of Public Health said in a statement. People who were in Terminal B between 10:45 p.m. on Jan. 26 and 1 a.m. on Jan. 27 may have been exposed.

Saturday’s warning noted that traveler also visited healthcare settings in LA County and at least one other public exposure location: A Dunkin’ Donuts at 22020 Ventura Blvd. in Woodland Hills on Jan. 30 between 3 p.m. and 4:45 p.m.

The Orange County Health Care Agency said the same individual visited locations at the Disneyland Resort while infectious on Jan. 28. Potential exposure windows include Goofy’s Kitchen at the Disneyland Hotel from 10:30 a.m. to 1:30 p.m., as well as Disneyland Park and Disney California Adventure Park from 12:30 p.m. until closing.

Passengers seated near the infected traveler on affected flights are being notified by local health departments in coordination with the Centers for Disease Control and Prevention. Healthcare facilities and Disneyland are contacting patients, staff and employees who may have been exposed.

Saturday’s warning from the LA County Department of Public Health involved the second confirmed case of measles in LA County this year. On Friday, the agency reported the first case of 2026 involving a resident who recently traveled internationally.

“There are no identified public exposure locations in Los Angeles County outside of a healthcare setting at this time,” Public Health said in Friday’s announcement. “Affected healthcare facilities are directly notifying patients and staff who may have been exposed. Public Health is also identifying others who may have had contact with the case and verifying their measles vaccination status.”

According to Orange County health officials, data from the Centers for Disease Control and Prevention show that as of Jan. 30, 2026, there have been 588 confirmed measles cases reported nationwide this year. By comparison, 2025 recorded 2,267 cases, the highest annual total in more than 30 years.

The exposure warnings come amid recent measles activity in Orange County, where health officials on Friday reported a measles infection in a toddler, days after confirming a case in a 19-year-old who had traveled internationally.

Health officials said people exposed may develop symptoms between seven and 21 days after exposure and urged residents to confirm their vaccination status.

“Measles doesn’t only affect people who travel internationally everyone is at risk if they’re not protected,” said Dr. Anissa Davis, Orange County’s deputy health officer. “The best way to protect yourself and your loved ones is to get vaccinated before exposure occurs.”

Anyone who develops symptoms such as fever, cough, runny nose, red eyes or rash should stay home and contact a healthcare provider before seeking care, officials said.
