Public Health Confirms Measles Case in Los Angeles County

The Los Angeles County Department of Public Health May 26 was notified of one case of measles in a non-Los Angeles County resident who traveled to Los Angeles International or LAX airport while infectious on May 19.  

This person arrived on Lufthansa flight LH 452 at the Tom Bradley International Terminal (TBIT) B, Gate 156 on May 19, 2024, at 3:04 p.m. and connected to flight LH 7852 at Terminal 7, Gate 82 at 8 p.m. There are no additional locations where possible exposures to this traveler may have occurred. 

Individuals who were at LAX TBIT and Terminal 7 from approximately 3:04 p.m. to 9 p.m. may be at risk of developing measles due to exposure to this traveler. In collaboration with the Centers for Disease Control, passengers assigned to specific seats that may have been exposed on Lufthansa flight LH 452 on May 18-19, 2024, and LH 7852 on May 19, will be notified of exposure by local Departments of Health.  

Exposed individuals should confirm if they have been vaccinated against measles. If they have not had measles in the past and have not yet obtained the measles vaccine, they are at risk of contracting measles if they have been exposed. Unimmunized persons or those with unknown immunization status who were at this location during the date and times listed above are at risk of developing measles from 7 to 21 days after being exposed. Exposed individuals who have been free of symptoms for more than 21 days (June 9) are no longer at risk. 

People who were in the location above around the aforementioned times should: 

• Review their immunization and medical records to determine if they are protected against measles. People who have not had measles infection or received the measles immunization previously may not be protected from the measles virus and should talk with a health care provider about receiving measles, mumps and rubella (MMR) immunization.
• Contact and notify their health care provider as soon as possible about a potential exposure if they are pregnant, an infant, have a weakened immune system and/or are unimmunized regardless of vaccination history.
• Monitor themselves for illness with fever and/or an unexplained rash from 7 days to 21 days after their exposure (the time period when symptoms may develop).
• If symptoms develop, stay at home, and avoid school, work and any large gatherings. Call a healthcare provider immediately. Do not enter a health care facility before calling them and making them aware of your measles exposure and symptoms. Public Health can assist health care providers in appropriately diagnosing and managing your care.

Common symptoms for measles include: 

• High fever (higher than 101° F)
• Cough
• Runny nose
• Red and watery eyes
• Tiny white spots that may appear inside the mouth 2-3 days after symptoms begin.
• Rash 3-5 days after other signs of illness. The “measles rash” typically starts at the face and then spreads down to the rest of the body.

About Measles 

Measles can be prevented with a measles, mumps, and rubella vaccine (MMR or MMRV). The MMR vaccine protects against three diseases: measles, mumps and rubella. The MMRV vaccine protects against four diseases: measles, mumps, rubella, and varicella (chickenpox). They are administered in two doses and are highly effective: two doses are 97% effective against measles and one dose is 93% effective. The spread of measles can be prevented if 2-dose coverage of vaccine remains at 95% or above in the community. For more information on measles, visit: ph.lacounty.gov/measles.
