Zusammenfassung:CONTEXT.— Community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections in children have occurred primarily in individuals with recognized predisposing risks. Community-acquired MRSA infections in the absence of identified risk factors have been reported infrequently. OBJECTIVES.— To determine whether community-acquired MRSA infections in children with no identified predisposing risks are increasing and to define the spectrum of disease associated with MRSA isolation. DESIGN.— Retrospective review of medical records. PATIENTS.— Hospitalized children with S aureus isolated between August 1988 and July 1990 (1988-1990) and between August 1993 and July 1995 (1993-1995). SETTING.— The University of Chicago Children's Hospital. MAIN OUTCOME MEASURES.— Prevalence of community-acquired MRSA over time, infecting vs colonizing isolates, and risk factors for disease. RESULTS.— The number of children hospitalized with community-acquired MRSA disease increased from 8 in 1988-1990 to 35 in 1993-1995. Moreover, the prevalence of community-acquired MRSA without identified risk increased from 10 per 100000 admissions in 1988-1990 to 259 per 100000 admissions in 1993-1995 (P
