Adapted by scientists from Flinders Health and Medical Research Institute (FHMRI) and SAHMRI, the technology is based on using germicidal ultraviolet (GUV) appliances which purify the air with UV-C light rays and deactivate harmful microorganisms like viruses and bacteria.

The new study, published in JAMA Internal Medicine, trialed commercially available GUV appliances in aged care facilities, finding they reduced rates of viral respiratory infections in vulnerable older Australians by more than 12%.

“Some of the key advantages of germicidal ultraviolet air-treatment appliances are that they are easily installed into existing facilities and cost-effective to use,” says lead author Dr. Andrew Shoubridge from Flinders University and SAHMRI’s Microbiome and Host Health Program.

“When used in conjunction with existing infection control measures, they could be transformative in reducing rates of seasonal respiratory viral infections and protecting residential aged care facilities against emerging pathogens.”
