If China’s new coronavirus turns into a prolonged outbreak, the country’s travel and leisure industry will likely be among the hardest hit.

News of the pneumonia-causing virus first emerged in late December in the city of Wuhan, about 700 miles south of Beijing. At least nine people have died from the disease. Authorities have also confirmed more than 400 cases, primarily in China, but other countries have also reported the illness, including the first U.S. instance overnight.

It’s unclear how threatening the virus ultimately is, but the acceleration of the outbreak has evoked fears of another epidemic similar to the severe acute respiratory syndrome, or SARS, which broke out in late 2002 in China.
