Depends if they have a wound colonized with MRSA or a systemic infection? If they have a systemic infection, you need systemic antibiotic treatment (often for at least 6 weeks). If it's local, I've had good success resolving colonization with Medihoney - but I'm not sure if it's FDA approved. Don't be positive the MRSA came from the hospital either - there is a large rise in community-acquired MRSA.
