Scientists Consider Indoor Ultraviolet Light to Zap Coronavirus in the Air

As society tries to rebound from the coronavirus pandemic, some scientists hope a decades-old
technology could zap pathogens out of the air in stores, restaurants and classrooms, potentially playing a key role
in containing further spread of the infection.
It has the ungainly name of upper-room ultraviolet germicidal irradiation, and it is
something like bringing the power of sunlight indoors.
“We have struggled in the past to see this highly effective, very safe technology fully
implemented for airborne infections,” said Dr. Edward A. Nardell, a professor of global health and social medicine
at Harvard Medical School. “We’ve done the studies. We know it works.”
