SEATTLE (AP) — A Seattle hospital said four staff members who have tested positive for COVID-19 work in or near the facility’s operating rooms.

A spokesperson for Virginia Mason Medical Center confirmed the positive tests occurred within the last week, The Seattle Times reported Sunday.

After three employees tested positive for the coronavirus, surveillance testing of more than 650 other staff members discovered one additional employee had developed COVID-19.

Media-relations Manager Gale Robinette said in a statement that each staff member who tested positive has been treated and will remain at 凯发k8地址home for at least two weeks in accordance with guidelines issued by the Centers of Disease Control and Prevention.

“We have not identified any risk of exposure to patients, as these team members were always wearing appropriate personal protective equipment while in their presence,” Robinette said.

Robinette did not respond to questions concerning the number of patients those staff members came in contact with or whether the patients would be notified and tested.
