Methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) are important causes of morbidity and mortality in hospitals, and rates of MRSA and VRE in long-term care facilities (LTCF) have increased. However, the majority of residents in LTCF are asymptomatically colonized and the risk of infection with MRSA or VRE in this setting is low. Extension of stringent infection control practices required to control the spread of MRSA and VRE in acute care hospitals is not warranted in the LTCF setting. Patients known to be colonized with MRSA or VRE should not be refused admission to a LTCF and, in the absence of symptomatic infection, measures beyond routine standard precautions are not necessary.
