Contact your local Department of Health and Human Services office to disclose the case.
Notify other employees who have been in contact with the employee in the workplace. Employees who worked closely with that employee should be sent home for a 14-day self-quarantine, negative test for COVID-19 or clearance by a doctor to return to work. When notifying office employees, do not disclose the infected employee’s name for risk of violating confidentiality laws.
Have the office deep cleaned.
If you work in a shared office building or area, you should inform building management so they can take whatever precautions they deem necessary.
