Yet another blow is struck against UV light devices.
Robert Baltimore, an infectious-disease specialist at Yale School of Medicine, says it's true that ultraviolet light kills bacteria, but questions the need for the devices. "Most of these bacteria are harmless to us, and providing a sterile environment is fruitless," he says. Most transmission of disease occurs from person to person, not from the environment, he adds.

I'd add that we may well be over-sterilized now. Reports of hard to kill infections acquired during hospital stays are too many.
