Proposed definitions of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA).

A new type of methicillin-resistant Staphylococcus aureus (MRSA) is emerging as a significant pathogen in otherwise healthy individuals in the community. This MRSA is distinct from healthcare-associated (HA)-MRSA, in terms of epidemiology, microbiology and clinical manifestations. At present there is a lack of consensus as to the terminology used to describe community-associated (CA)-MRSA. This confusion is further compounded with the recent emergence of nosocomial transmission of CA-MRSA within hospitals. The aim of this article is to highlight the differences between HA-MRSA and CA-MRSA and to propose standard definitions of the various subgroups of CA-MRSA.
