Shares of the three U.S. airlines that fly to China fell on Tuesday as fear grew about a virus that authorities say has killed six people and sickened 300 more.
The United States reported its first case, a Washington state resident who returned last week from China and was hospitalized in good condition.
Investors worried that the virus could spread beyond Asia, like the SARS outbreak in 2002, which hurt travel between the U.S. and Asia.
In afternoon trading, shares of Hawaiian Airlines' parent fell 5.8%, United Airlines dropped 4.3%, American Airlines lost 3.9%, and Delta declined 3%.
Other stocks in the travel sector also took a hit Tuesday, including hotel chains like Marriott, which fell 4%. Hilton was down 2.8% and Wyndham slipped 1.3%. Meanwhile, Royal Caribbean Cruises slid 4.3%.
“We’re obviously watching it carefully, it’s still way too early to talk about," Marriott CEO Arne Sorenson told CNBC Tuesday. “I think the Chinese authorities have got to make sure they understand what’s going on and we’ll have to watch and see what we learn from it.”
The outbreak is believed to have started in Wuhan in central China. None of the U.S. airlines fly to Wuhan, but their Chinese partner airlines do, and some passengers transfer from Chinese carriers to American ones.
Fear about the virus increased just as millions of Chinese prepared to travel for the lunar New Year holiday, which starts Saturday. Cases have also been confirmed in Japan, South Korea and Thailand.
