Los Angeles County reports 5th case of measles so far in 2026

LOS ANGELES (CNS) — Los Angeles County health officials reported a confirmed case of measles on Saturday in a resident who recently traveled internationally, the fifth case of measles reported by the county in 2026.

The traveler arrived on Alaska Airlines flight 1354 at the Tom Bradley International Airport Terminal B on Thursday, according to the Los Angeles County Department of Public Health. Individuals who were at Terminal B from 6 a.m. to 8 a.m. that day may have been exposed to the measles virus.

“In collaboration with the U.S. Centers for Disease Control and Prevention, passengers seated near the infected traveler will be notified by their respective local health departments,” the department said.

People who were at the location during the specified date and times may be at risk of developing measles from 7 to 21 days after being exposed and should confirm their protection against measles, officials said.

Those who have had measles in the past or received the recommended measles vaccine are likely protected but should still monitor for symptoms. Anyone who remains symptom-free for more than 21 days after being exposed is no longer considered at risk. The last day to monitor for symptoms is June 4, 2026.

Affected healthcare facilities are directly notifying patients and staff who may have been exposed, and the county health department is working to identify any other potential exposure sites in Los Angeles County, officials said.

Measles symptoms include fever, cough, red-watery eyes and a rash that usually starts on the head and spreads over the rest of the body, officials said. It is the most contagious disease and spreads through the air and by direct contact with the infected person. People can be contagious for about four days before they notice a rash.

Anyone who thinks they may have measles is encouraged to call their doctor before going to a medical office to avoid spreading it. Experts say vaccination is the most effective way to prevent measles.
