Those guidelines list two strategies, testing and not testing.
If an employee is tested they are to be off work until there is no fever, an improvement in symptoms, and there are negative results for two swabs taken 24 hours apart.
If an employee is not tested they can return after there is no fever, and improvement in symptoms, and it's been seven days since the onset of symptoms.
The hospital's guidelines for a positive with no symptoms is to keep working, and with symptoms to return after the fever is reduced and the symptoms improve. They are leaving out the negative test results the CDC recommends.
The hospital's guidelines for employees that aren't tested are to return once the fever is reduced. That's it. No improvement of symptoms and seven says since onset of symptoms as recommended by the CDC.
