A worker that was based out of Facebook’s (FB) Seattle offices has reportedly tested positive for the coronavirus.

Facebook has closed its Stadium East office, where the employee was stationed until Monday through the fill incubation period that the worker will go through, CNBC reported.

“A contractor based in our Stadium East office has been diagnosed with COVID-19. We’ve notified our employees and are following the advice of public health officials to prioritize everyone’s health and safety,” a company spokesperson told the news outlet.

Facebook has reportedly taken action and has told its Seattle-based employees to work from home until March 31. The announcement comes as King County, Washington, issued a guidance on preventing the spread of the virus in the state.

Washington has been the epicenter of coronavirus outbreaks in the U.S., with at least 10 people dying from the virus since the first incident was reported. A total of 39 confirmed cases of COVID-19 have been reported in Washington, with another 231 people under supervision by health officials, according to the Washington State Department of Health.

Washington state is also home to outdoor sporting good company, REI, which has closed its offices for deep cleaning, and several Amazon offices, where a worker also tested positive for the coronavirus.
