Overview
- The traveler was infectious in Los Angeles on Thursday, June 11 and moved through Cathay Pacific flight CX884, the Tom Bradley International Terminal, the Hilton Los Angeles Airport Hotel shuttle and the hotel itself before visiting local healthcare facilities.
- Los Angeles County Public Health identified specific exposure windows at the Tom Bradley terminal and the Hilton hotel on June 11 and said the last day for exposed people to monitor for symptoms is July 2.
- Officials are working with the CDC to contact passengers who sat near the traveler and health-care sites are notifying patients and staff who may have been exposed while county teams conduct contact tracing.
- Health leaders urged people to check their immunity and get the MMR vaccine when needed because two doses are about 97% effective and most recent U.S. and California cases have been among the unvaccinated.
- The case comes as the U.S. has recorded more than 2,000 measles cases in 2026 and California reported 50 cases as of June 12 with large international outbreaks and World Cup travel cited as factors that raise importation risk.
