Portable UV light as an alternative for decontamination

      Highlights

      • Mobile phones and tablet PCs at the patient's site may be a source of pathogen transmission.
      • Standard disinfection reprocessing procedures might not be appropriate for these electronic devices.
      • UV radiation using a hand-held device may be considered as an alternative for decontamination of those items.
      We evaluated the capability of a commercially available hand-held device that emits ultraviolet (UV) light to disinfect plain surfaces. Eight bacterial species were tested, including Clostridium difficile ribotype 027 and 3 other spore-forming species. Even bacterial spores could be successfully inactivated within a few seconds of irradiation. UV light may provide an alternative for the decontamination of medical products, such as mobile phones or tablet computers, that cannot be treated otherwise.
