A flight attendant who has worked on flights out of Los Angeles International Airport was recently diagnosed with coronavirus.

The South Korean Centers for Disease Control and Prevention confirmed that a Korean Air flight attendant servicing flights between LAX and Seoul, South Korea on Feb. 19 and 20, was diagnosed with the strand linked to dozens of cases of COVID-19.

Officials from the South Korea Centers For Disease Control also confirmed that the woman serviced a flight from Tel Aviv, Israel to Seoul on Deb. 15 where at least 200 passengers were aboard.

At least 30 members of a church group on that flight were diagnosed with coronavirus, as reported in Fox 5 San Diego.

Korean Air has not released the flight attendant’s full routing since contracting the virus but it’s believed that the employee worked additional flights to and from Seoul in the days following the flight to Israel, according to South Korean news outlets. 

About 1,150 cases of coronavirus have been reported in South Korea, including a 23-year-old U.S. service member stationed in the country.

The soldier “is currently in self-quarantine at his off-base residence… Korean and U.S. military health professionals are actively conducting contact tracing to determine whether any others may have been exposed,” according to a U.S. Forces Korea statement.
