Control measures in identified MRSA carriers consisted of contact precautions, antibiotic prophylaxis with a single dose of vancomycin 1g in addition to cephalosporins, and topical decolonization of MRSA (application of 2% mupirocin ointment twice daily to nares for 5 days and a bath with 4% chlorhexidine daily for 3-5 days). Although contact precautions were used when caring for MRSA-colonized patients, isolation/cohorting was not routinely practiced.
