PURPOSE: The study's purpose was to elucidate the evolutionary, microbiologic, and clinical characteristics of methicillin-resistant Staphylococcus aureus ( MRSA) infections.METHODS: MRSA cases from military medical facilities in San Diego, from 1990 to 2004, were evaluated and categorized as community- acquired or nosocomial. Sequence type, staphylococcal chromosomal cassette gene type, and Panton- Valentine leukocidin gene status were determined for a subset of isolates.RESULTS: Over the 15- year period, 1888 cases of MRSA were identified; 65% were community acquired. The incidence ( 155 infections/ 100 000 person- year in 2004) and household- associated cases rapidly increased since 2002. Among persons with community- acquired MRSA, 16% were hospitalized and only 17% were initially given an effective antibiotic. Community- acquired MRSA cases compared with nosocomial MRSA cases were more often soft- tissue and less often urinary, lung, or bloodstream infections ( P
