Risk Factors for Community-Acquired Methicillin-Resistant Staphylococcus Aureus (CAMRSA) Infectors in Military Trainees: Review of an Outbreak in San Diego, California, 2002
Abstract:
An outbreak of community-acquired methicillin-resistant Staphylococcus aureus CA-MRSA skin infections was observed in a population of US military trainees in the summer of 2002. A questionnaire was developed and administered to 209 trainees, 22 of whom had MRSA infections. Factors associated with infection were described by multivariable logistic regression modeling, and included having a roommate in training with a prior skin infection odds ratio OR 3.44, or having a family member or friend who worked in a healthcare setting OR 2.79. Previous antibiotic use, hospitalization, or health problems were not associated with MRSA infection. This outbreak of MRSA skin infections in an otherwise healthy, well-defined, military population provided an opportunity to describe risk factors for CA-MRSA, which may help focus prevention efforts in this and other communities.
