A recent study found ultraviolet lamps installed over computer mice and keyboards reduced bacteria 99 percent, according to an article on the Becker's Infection Control & Clinical Quality website.
Cultured samples from 203 mice and keyboards in intensive care units revealed that 193 of them (95.1 percent) had bacteria growth.
The hospital installed automated UV-C lights over the computer mice and keyboards in the ICUs.
After installation, 205 keyboards and mice were sterile, while 13 had bacterial growth.
