UV light may be used to fight the flu in public places

It’s the light fantastic — one that fights the flu.

Researchers at Columbia University Medical Center are developing far-UVC — a special type of ultraviolet light — that could be used in public places and offices to kill the airborne influenza virus and stop the spread in its tracks.

Scientists know that broad-spectrum UVC is a potent germicide. It kills bacteria and viruses by breaking down their molecular bonds and is used to decontaminate surgical equipment.

“Unfortunately, conventional germicidal UV light is also a human health hazard and can lead to skin cancer and cataracts, which prevents its use in public spaces,” said lead author David J. Brenner.
