MRSA carriers among hospital personnel

Should members of the hospital personnel who do not have direct contact with patients, like cleaners or accessory personnel, and who are carriers of a multidrug-resistant strain, such as methicillin-resistant Staphylococcus aureus, continue to work as normal? Or should they refrain from working until the cultures are negative?

Mark Loeb: Sometimes that is a very difficult question because you really have to see where they are working, who are they working with, what exactly is their exposure to patients. It might be reasonable to do that if they are working with a very high-risk unit, a hematology unit or wherever where the risk of transmission would be very high. I would say generally no, but it just depends.
