McDonald’s Corp. has temporarily closed locations across five cities of China’s Hubei province due to a rapidly spreading lung virus.

All restaurants in the cities of Wuhan, Ezhou, Huanggang, Qianjiang and Xiantao are closed as of Jan. 24, Chicago-based McDonald’s said in a statement. The locations correspond with areas where public transportation has been suspended. The company didn’t specify the number of locations that have been closed.

In the rest of the company’s restaurants in China that are operating normally, the company is taking extra preventative measures. These include taking the temperature of workers upon arrival and giving out hand sanitizer to diners.

Businesses are responding as China takes unprecedented steps to contain the outbreak of the virus, including travel restrictions for 40 million people on the eve of the Lunar New Year -- one of the busiest travel times. The coronavirus has been reported in 32 of 34 provinces and a second U.S. case was confirmed on Friday. The impact on the economy is still uncertain, with executives at the world’s biggest companies saying they’re waiting for more information to emerge on the scope of the outbreak.

McDonald’s had about 3,000 stores in China at the end of 2018.
