A Nosocomial Outbreak of Community-Associated Methicillin-Resistant Staphylococcus aureus among Healthy Newborns and Postpartum Mothers

Abstract

BACKGROUND: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) has increasingly been isolated from individuals with no predisposing risk factors; however, such strains have rarely been linked to outbreaks in the hospital setting. The present study describes the investigation of an outbreak of CA-MRSA that occurred in the maternal-newborn unit of a large community teaching hospital in Toronto, Ontario.
