An Amazon (AMZN) worker has reportedly tested positive for the coronavirus at the e-commerce giant’s Seattle offices.

The employee reportedly worked at the company’s Brazil office building, and not the company’s corporate headquarter location, which is also in Seattle.

Amazon employees were notified in a memo obtained by CNBC that read, “The employee went home feeling unwell on Tuesday, February 25 and has not entered Amazon offices since that time.

“We notified the employees who we know were in close contact with this employee. The risk of transmission for employees who were not in close contact with this individual is assessed to be low,” the memo continued.

Amazon also urged any employee experiencing coronavirus symptoms to stay home and get medical treatment.

Amazon told CNBC, “We’re supporting the affected employee who is in quarantine.”
