Abstract
Background and Objective: Since the early 2000s, the incidence of
methicillin-resistant Staphylococcus aureus (MRSA)
infections among the community of people lacking known healthcare risk factors has
increased. This MRSA infection is referred to as community-associated MRSA (CA-MRSA)
infection and is distinct from hospital-associated MRSA (HA-MRSA) infection, which occurs
among people with known healthcare risk factors. Understanding the epidemiology of CA-MRSA
infections is critical; however, this has not been investigated in detail in Japan. Our
objective was to investigate the incidence of CA-MRSA infections in a regional
hospital.
Patients and Methods: We investigated CA-MRSA isolates and infections in a
rural regional hospital by reviewing medical records of one year. Infections were
classified as CA-MRSA if no established risk factors were identified.
Results: During 2008, 31 Staphylococcus aureus (S.
aureus) isolates were detected in 29 unique patients, with 1
methicillin-sensitive S. aureus (MSSA) isolates obtained from 19 patients
(66%) and MRSA obtained from 10 patients (34%). In the 10 patients with MRSA, the number
of HA-MRSA and CA-MRSA cases were nine (32% of patients with S. aureus
isolates) and one (3%), respectively. The patient with CA-MRSA was diagnosed with
cellulitis due to CA-MRSA. All nine patients with HA-MRSA exhibited colonization.
Conclusion: We observed a CA-MRSA case in a regional hospital in Japan,
suggesting that incidence trends of CA-MRSA should be considered in future research and
treatment.
