MRSA Outbreak

Overview

A MRSA outbreak is the occurrence of 3 or more related MRSA infections. The infections are related because they stem from a common source. The source is the person from whom the bacteria initially spread. 

Note: Outbreaks occur with both community-associated MRSA and healthcare-associated MRSA. 

Confined Groups 

• MRSA outbreaks occur more frequently in confined groups. Increased personal contact presents greater opportunity for the spread of MRSA bacteria. Confined groups include: 
  • Schools
  • Dormitories
  • Long-term care facilities
  • Correctional facilities

Prompt Action Required

• MRSA outbreaks require prompt action, usually with the assistance of the local health department. The goal is to: 
  • Isolate the source, and
  • Prevent spread of infection.
