The iPhone maker has two main headquarters in Cupertino, California, — the Apple Park campus and its original Infinite Loop set of buildings — in addition to offices elsewhere in Santa Clara County. Apple also is offering workers in Seattle the option to work from home. The company employs engineers in Seattle on machine-learning technology.

The work-at-home policy is in effect for Friday, Apple said in a statement. The company didn’t comment on future plans.

Apple retail stores in the San Francisco Bay Area remain open, but the company is limiting some “Today at Apple” classes in the region and in the Seattle area, which has the largest number of confirmed coronavirus cases in the U.S. The iPhone maker also is spacing out Genius Bar service appointments throughout the stores so people are not as close to one another.

Apple’s supply chain has been impacted by the virus as well, with devices like the iPad Pro and replacement iPhones seeing shortages, Bloomberg News has reported. The company has also restricted employee travel to China, South Korea and Italy.

More than 100,000 cases of the virus known as Covid-19 have been confirmed, resulting in 3,405 deaths. There are 126 illnesses in the U.S., according to data compiled by Bloomberg.
