According to health officials, the traveler arrived aboard Alaska Airlines Flight 1354 at Tom Bradley International Airport (TBIT) Terminal B on May 14, 2026. Public Health officials warned that individuals who were inside Terminal B between 6 a.m. and 8:00 am that morning may have been exposed to the highly contagious virus.
In coordination with the Centers for Disease Control and Prevention (CDC), local health departments will notify passengers seated near the infected traveler. Federal and local public health agencies routinely collaborate to investigate communicable disease exposures on international flights entering the United States.
Health officials said people who were at the airport during the identified exposure window could develop measles symptoms between seven and 21 days after exposure. The final day for exposed individuals to monitor for symptoms is June 4, 2026.
Officials advised residents to confirm their measles immunity status. Individuals who previously had measles or received the recommended measles-mumps-rubella (MMR) vaccine are considered likely protected, though they should still monitor for symptoms. Unvaccinated individuals or those uncertain of their vaccination status face a higher risk of infection.
Healthcare facilities potentially affected by the exposure are directly notifying patients and staff who may have been exposed. Public Health officials are also continuing efforts to identify additional exposure sites throughout Los Angeles County.
The Department of Public Health emphasized that ongoing measles outbreaks in the United States and abroad increase the importance of vaccination before travel.
“The MMR vaccine is the safest and most reliable way to prevent measles and protect yourself, your family, and your community,” said Muntu Davis, MD, MPH, Los Angeles County Health Officer. “Measles spreads easily and can lead to serious complications, including pneumonia, brain swelling, and even death.”
Health officials urged residents to review immunization records before traveling, especially for international travel or trips to areas experiencing outbreaks. Infants between 6 and 11 months old traveling to outbreak areas are advised to receive an early dose of the MMR vaccine at least two weeks before departure.
Public Health also advised anyone who may have been exposed and is pregnant, immunocompromised, unvaccinated, or caring for an infant under 12 months old to contact a healthcare provider immediately for guidance.
Residents are being told to watch for symptoms including fever, cough, runny nose, red eyes, and rash. Anyone who develops symptoms should remain at home, avoid public gatherings, and contact a healthcare provider before visiting a medical facility to prevent further spread of the virus.
