Touchscreens are a potential source of pathogen transmission. In our facility, patients and visitors rarely perform hand hygiene after using interactive touchscreen computer kiosks. An automated ultraviolet-C touchscreen disinfection device was effective in reducing bacteriophage MS2, bacteriophage ϕX174, methicillin-resistant Staphylococcus aureus, and Clostridium difficile spores inoculated onto a touchscreen. In simulations, an automated ultraviolet-C touchscreen disinfection device alone or in combination with hand hygiene reduced transfer of the viruses from contaminated touchscreens to fingertips.
