Existing UV light technology has potential to reduce COVID-19 transmission indoors

A recent study has shown that a UV light technology already used to prevent the spread of other airborne diseases in buildings has the potential to be effective against COVID-19.

The research, published in the journal PeerJ, found that upper room UV germicidal irradiation (UVGI) can kill SARS-CoV-2 virus particles, which can be transmitted by aerosolised droplets that float in the air.

UVC is known to be very effective at ‘killing’, or inactivating, microorganisms however this type of UV light is harmful to humans. Upper room UVGI cleverly uses UVC light to create an irradiation field above the heads of room occupants so it can disinfect the air whilst keeping people within the room safe.
