Patients with subsequent discrete MRSA infection within 1 year after the time of identification as a prevalent carrier.

Deaths occurring within 1 year after the time of detection as a prevalent carrier. Deaths attributable to MRSA are included within deaths associated with MRSA. Deaths associated with MRSA include deaths associated with MRSA infections present at enrollment and subsequent MRSA infections.
