A Korean Air flight attendant who worked multiple flights out of Los Angeles International Airport has been diagnosed with coronavirus, according to the Korea Joongang Daily newspaper.

The 24-year-old flight attendant was diagnosed Tuesday in South Korea. She had reportedly worked flights between LAX and Seoul–Incheon International Airport on Feb. 19 and 20, according to South Korean media outlets.

The flight attendant also worked a flight from Tel Aviv, Israel, to Seoul on Feb. 15, according to South Korea’s Center for Disease Control. The Yonghap News Agency reports that she may have contracted the virus from a South Korean church group who were on a pilgrimage to Israel.

South Korean health authorities have reported that at least 30 members of that church group have been diagnosed with coronavirus.

In the meantime, Korean Air has closed its operations center at Incheon Airport so they can disinfect the area.

The coronavirus, which originated in Wuhan, China, has spread around the world to countries including Italy, Japan, South Korea and the United States. A 23-year-old U.S. soldier stationed at Camp Carroll in South Korea has also tested positive for coronavirus, U.S. Forces Korea (USFK) confirmed in a statement on Tuesday. He is being quarantined off-base.

“Korea Centers for Disease Control and Prevention and USFK health professionals are actively conducting contact tracing to determine whether any others may have been exposed,” USFK said in the statement.

As of Monday, there were 53 confirmed coronavirus cases in the U.S. Globally, more than 80,000 people have been infected with the virus, which has claimed at least 2,700 lives.
