Should I send a co-worker notification to everyone in the department?

As a manager or supervisor, you are likely in the best position to have a sense of who was and was not in close physical contact with an employee who tests positive. If you are unsure of the status of whether an employee(s) should be included in the notification, we recommend erring on the side of caution and including the employee(s) in the distribution of the message.   While individuals who are working remotely all the time likely do not need to know of a confirmed positive case since they are not likely to have been exposed, being broad and inclusive in the notification mitigates the risk of missing anyone who should have been told.
