We investigated the prevalence of heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) among methicillin-resistant S. aureus (MRSA) blood isolates collected from Korean hospitals. The hVISA prevalence in Korean hospitals has decreased during the past decade and the most significant decrease of hVISA prevalence was observed among the ST5 MRSA.
