Methods and systems for mitigating pathogen transmission via a touch surface of a touch input device. Mitigation is accomplished through selective touch surface sterilization and through touchscreen user interface reorganization. The touch surface includes a pixel array for illuminating selected portions of the touch surface with ultraviolet light of a sterilization wavelength based upon the received touch inputs. The selective illumination may occur while receiving a touch input or after an accumulation of touch inputs have been received. The user interface may also be reorganized based on received touch inputs in order to locate user interface icons to lesser touched locations of the touch surface.
