Abstract

Computer keyboards are a potential source for dissemination of pathogenic microorganisms. We demonstrated that a low-intensity ultraviolet-C (UV-C) radiation device was effective in reducing methicillin-resistant Staphylococcus aureus, carbapenem-resistant Escherichia coli, and Clostridium difficile spores on steel carriers and significantly reduced bacterial counts on in-use keyboards.
