According to the LA Times, a passenger traveling through Los Angeles International Airport (LAX) potentially exposed other travelers to measles.
The patient was at LAX on Friday from 11 pm to 1:30 am Saturday, and spent time at Terminal 5 and aboard a Parking-Spot Century airport shuttle. Terminal 5 houses Allegiant Air, Frontier, Hawaiian Air, JetBlue, Spirit, Sun Country and some American Airlines flights.
Those who may have been in the vicinity around the same time are urged to check their immunization records and contact a healthcare provider if they have not been vaccinated. Symptoms of infection can take 21 days to appear from the time of exposure.
