Risk Factors for Community-Acquired Methicillin-Resistant Staphylococcus Aureus (CAMRSA) Infectors in Military Trainees: Review of an Outbreak in San Diego, California, 2002

摘要

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.
