Health officials have revealed that a traveler with measles went through Los Angeles International Airport (LAX) on an international flight last week. This comes just days after another measles case was reported at San Francisco International Airport.
With both cities welcoming international fans for World Cup matches, there’s a growing concern about the potential spread of this highly contagious disease.
The individual passed through LAX on June 11, between 10 a.m. and 12 p.m., specifically in the Tom Brady International Terminal B.
Potential additional exposure sites include the Hilton Los Angeles Airport Hotel on the same day from 11:15 a.m. to 12:15 p.m.
Officials have advised anyone who was in these locations during those hours to be vigilant for any signs of infection.
Symptoms like fever, cough, runny nose, red eyes, and rashes might show up seven to ten days after exposure.
Unvaccinated individuals are encouraged to isolate for up to three weeks, to steer clear of large crowds, and to monitor for any health changes.
There’s a particular emphasis on pregnant women, infants, and those with weakened immune systems—all should seek medical advice promptly if they think they may have been exposed.
This incident marks the sixth reported case of measles in Los Angeles County this year, following the situation at San Francisco International.
“As summer travel increases, especially with the influx of visitors during World Cup events, the risk of infectious diseases rises,” noted Dr. Muntu Davis, the Los Angeles County Health Officer.
“We urge everyone to check their immunity for measles, mumps, and rubella, and get vaccinated if necessary, particularly before attending crowded events or traveling.”
Health officials reminded anyone experiencing symptoms to contact their healthcare provider before visiting in person to help curb further spread.
As of June 12, California has recorded 50 confirmed measles cases, which is nearly double the total from all of 2025 and the highest number since 2019.
The timing of this outbreak is concerning, as tourists flock to Los Angeles and the Bay Area for the ongoing World Cup, raising fears of an increase in cases.
Statistics indicate that 94% of those infected are unvaccinated, with over 80% being under the age of 19.
Dr. Davis emphasized that the MMR vaccine is the most effective way to prevent measles and safeguard families and communities.
County health officials are collaborating with the California Department of Public Health and the U.S. Centers for Disease Control and Prevention to track contacts related to the exposure sites.
Additionally, officials advised travelers to take precautions and ensure vaccinations are up to date before heading to Mexico, another host country for the World Cup, where the measles epidemic continues to persist, with over 18,000 cases anticipated in 2026.
