Recurrent Staphylococcus aureus infections are a major problem. In their report on an intensive environmental investigation of the homes of persons diagnosed with community-acquired methicillin-resistant S aureus (MRSA) published in this issue of JAMA Internal Medicine, Knox and colleagues1 found that the clinical isolate that caused the initial infection could be cultured from the surfaces of 24.4% of the homes, including television remotes, door knobs, computers, and couches. Of greater importance, patients from houses where MRSA could be cultured were twice as likely to develop a recurrent infection.
