What treatment and/or confirmatory testing are required before a health-care professional who has been diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) infection can resume working with patients?—MIEN-CHI CHEN, MD, Seattle

According to the CDC’s Guidelines for Infection Control in Health Care Personnel, restriction from patient-care activities or food handling is indicated for personnel who have draining skin lesions that are infected with S. aureus until they have received appropriate therapy and infection has resolved. No work restrictions are necessary for personnel who are colonized with S. aureus unless they have been epidemiologically implicated in S. aureus transmission within the facility.—JoAnn Deasy, PA-C, MPH (148-4)
