BACKGROUND: The prevalence of community-acquired methicillin-resistant S. aureus (CA-MRSA) has been increasing worldwide. We aimed to investigate the prevalence of MRSA in community-acquired S. aureus infections, the risk factors for CA-MRSA infection and the clinical features of CA-MRSA. METHODS: A multi-center study with prospective and retrospective sections was conducted. Patients ≥ 3 months old and ≤18 years of age who were diagnosed with community-acquired S. aureus infections were included in this study and the patients` information were reviewed from the medical and microbiological database of the hospital. A standard question form about living conditions and exposure risk factors was administered to the parents of patients. The CA-MRSA infections were compared with the methicillin-susceptible S. aureus (CAMSSA) infections in terms of the queried risk factors and clinical variables. RESULTS: We identified 334 pediatric patients with S. aureus infection, 58 (17.4%) had an infection with CAMRSA. The refugee rate was higher in the CA-MRSA group. There was no significant difference regarding the exposure risk. The treatment modalities and outcomes were similar. CONCLUSIONS: The study was not able to show reliable clinical variables or epidemiological risk factors except for being a refugee for CA-MRSA infections. Empirical antibiotic treatment should therefore be determined according to the local CA-MRSA prevalence in patients presenting with a possible staphylococcus infection.
