Health officials in Los Angeles County are warning travelers and residents after confirming that a person infected with measles may have exposed others at Los Angeles International Airport and a nearby hotel earlier this month.

According to the Los Angeles County Department of Public Health, the traveler arrived on Cathay Pacific Flight CX 884 on June 11 and was infectious while moving through the county.

Authorities said potential exposure locations include the airport and the Hilton Los Angeles Airport Hotel.

Officials are now investigating the case, which marks the sixth confirmed measles infection in Los Angeles County this year.

The department cautioned that the risk of exposure may grow as international tourism increases over the summer and as the region prepares to host FIFA World Cup events.

Health authorities have identified specific windows of potential exposure.

Anyone at the Tom Bradley International Terminal between 10 a.m. and noon on June 11 may have been exposed, as well as those at the Hilton Los Angeles Airport Hotel at 5711 W. Century Blvd. between 11:15 a.m. and 12:15 p.m. that same day.

The Centers for Disease Control and Prevention is working with local health departments to notify passengers who were seated near the infected traveler on the international flight.

Officials said those who think they may have been in contact with the traveler should watch for symptoms for 21 days following the exposure date.

Potential symptoms of measles typically appear seven to 21 days after exposure.

Health officials advised that the last day for exposed individuals to monitor themselves for possible signs of infection is July 2.

Dr. Muntu Davis, Los Angeles County Health Officer, emphasized the importance of vaccination amid increasing measles activity. “As measles cases increase, it is important that residents take steps to make sure they are fully protected,” Davis said.

“The MMR vaccine is the safest and most reliable way to prevent measles and protect yourself, your family, and your community.”

Measles often begins with fever, cough, runny nose, and red or watery eyes, followed by a rash that usually starts on the face before spreading to the rest of the body. Health officials have not yet released additional details about the infected traveler.

The confirmed case adds to growing concern about rising measles numbers at major U.S. airports this year.

The situation underscores how quickly infectious diseases can spread through international travel hubs.

Local officials said they are continuing to trace potential exposures to ensure timely communication and intervention.

Travelers are advised to remain aware of any public health updates in the coming days.
