This paper describes a study concerning the prevalence of MRSA in one London general practice, screening 258 elderly people living in their own home. MRSA was found in two participants. A history of MRSA was the only significant risk factor. The results of this and other studies suggest that national guidelines recommending early discharge of MRSA carriers have not resulted in widespread community acquisition amongst elderly people living in their own homes.
