Measles Case on Cathay Flight 884 Exposes LAX, Hilton Visitors as 150,000 World Cup Travelers Arrive

Q: As the World Cup draws global crowds, is the US about to lose its fight against measles?

Yes. The United States is not losing the fight irreversibly, but it is at real risk of losing measles elimination status as World Cup travel increases opportunities for the virus to spread. The immediate danger is not the tournament itself but the conditions surrounding it: heavy international travel, crowded airports and hotels, and too many pockets of low vaccination. The recent measles exposures at LAX and SFO show how easily imported cases can arrive in major transit hubs. Measles is among the most contagious infections; one case can infect 12 to 18 others in an unvaccinated population, and the virus can linger in the air for hours. The broader trend is more troubling. The U.S. has reported 2,073 cases so far this year, nearly matching all of last year’s 2,288. National kindergarten MMR coverage has fallen to 92.5%, below the 95% level generally needed to prevent sustained spread. More than 90% of recent U.S. cases have been in unvaccinated people, and California says 47 of its 50 cases this year were in people unvaccinated or with unknown status. That does not mean widespread national transmission is inevitable. The U.S. still has the tools to stop it: rapid case detection, contact tracing, isolation, and above all vaccination. Two MMR doses are about 97% effective. If travelers, families and host cities act quickly—especially by closing immunity gaps—the World Cup can remain a stress test rather than the moment measles regains a permanent foothold.

L.A. County said a measles-infected traveler arrived on Cathay Pacific Flight 884 from Hong Kong on June 11, exposing people at LAX’s Tom Bradley terminal from 10 a.m. to noon and at the Hilton Los Angeles Airport Hotel from 11:15 a.m. to 12:15 p.m.
July 2 is the monitoring deadline for unimmunized or unknown-status contacts because measles can surface 7 to 21 days after exposure and spreads from four days before to four days after the rash appears.
This is the sixth measles case reported in L.A. County this year and the fourth involving a contagious passenger passing through LAX; nearby healthcare facilities are notifying potentially exposed patients and staff directly.
More than 150,000 travelers are expected in L.A. County from June 12 to July 10 for eight World Cup matches, prompting officials to urge vaccination and symptom checks as crowding raises exposure risk.
Across the Americas, measles cases have topped 20,000 this year—about quadruple 2025 levels—while California has reported 50 infections, its highest annual total since 2019.
