Amazon is informing employees that one of its Seattle-based workers has been diagnosed with coronavirus.

According to a mass email for all staff members in Seattle and Bellevue, Washington, the employee infected with the novel coronavirus first became ill on February 25 and has not been back to work since that time.

The company said it has directly notified all coworkers who had been in close contact with the patient. The worker was based at the downtown office building the company refers to as Amazon Brazil, according to the email.

An Amazon spokesperson confirmed the authenticity of the email to CNN, adding, “We’re supporting the affected employee.”

It was not immediately clear whether the case was included in Washington state’s count of coronavirus patients in King County, which stood at 21 on Monday.
