Dissemination of methicillin-resistant Staphylococcus aureus and bacteriophage MS2 from floors in long-term care facility resident rooms

Published:September 30, 2022DOI:


      • Floors and shoes are potential sources for dissemination of pathogens.
      • Shoes and wheelchair wheels transferred MRSA from room to room.
      • A benign virus inoculated on the floor disseminated to high-touch surfaces.
      • Studies of floor or shoe disinfection are needed.


      We demonstrated that methicillin-resistant Staphylococcus aureus (MRSA) contamination on floors in the rooms of colonized long-term care facility residents was frequently transferred by shoes to adjacent patient rooms. A benign virus inoculated onto the floor was transferred to floors and high-touch surfaces in adjacent rooms and the nursing station. These results suggest that shoes may serve as a vector for dissemination of health care-associated pathogens from rooms of MRSA-colonized patients.
