A new type of ultraviolet light can efficiently kill airborne microbes, such as those which cause COVID-19, a study has found after successful trials.

The result suggests that this light, known as Far-UVC, could be used to significantly reduce the risk of person-to-person indoor transmission of hospital-acquired infections as well as airborne diseases such as COVID-19 and influenza.

Published in Nature Scientific Reports, the research carried out by the Universities of Leeds, St Andrews, Dundee and Columbia University in New York with NHS Tayside is the first study to measure the performance of Far-UVC under full-scale conditions.

The researchers released an aerosolised bacteria known to be harder to inactivate than the SARS-CoV-2 virus which causes COVID-19, into a room-sized chamber and then tested the level of microbial reduction when it was exposed to the Far-UVC light.

Dr David Brenner, of the University of Columbia in New York, said: “We now know that Far-UVC light is superbly efficient at killing airborne microbes. And based on our earlier studies we have very strong evidence that is will be equally good at killing all the COVID-19 variants, past, present and future, as well as the “old fashioned viruses” like influenza and measles.

“So, by simply adding UV light to the conventional lighting in indoor rooms, we can quickly kill all the airborne viruses in the room and so protect ourselves against person-to-person indoor disease transmission.”

The team received a grant of £136,000 from the UK Health Security Agency to carry out the trials – and they will continue their research into the safety and efficacy of Far-UVC lights through two recently awarded grants totalling £270,000 from the UK Health Security Agency and NHS Scotland Assure.

The results coincide with a decision by the US agency which decides on safety regulations for UV light, the American Conference of Governmental Industrial Hygienists, to increase the allowable Far-UVC light exposure in the US seven-fold.

Care222 is a new disinfecting light source that, even though not harmful to the skin or eyes of humans or animals, deactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers.

Does not cause sunburn, skin cancer or cataracts

Ultraviolet rays with a wavelength of 222 nm are absorbed by the cornea of ​​the stratum corneum of dead cells, so they do not cause damage such as sunburn, skin cancer, and cataracts.

Virus suppression / sterilization

Ultraviolet rays with a wavelength of 222 nm destroy the DNA / RNA structure of viruses and cells, and suppress and sterilize them.

A key advantage of the UV-based approach is that UV light is likely to be effective against all airborne microorganisms, in marked contrast to vaccination methods. For example, while the inactivation efficiency of UV light will almost certainly vary as different strains of influenza virus emerge, they are unlikely to be significant. Similarly, as multidrug-resistant variants of bacteria emerge, their UV inactivation capacity is unlikely to vary greatly.

 

 

 

 

The use of Care222 in public places is a safe and effective way to limit the spread and transmission of air-mediated microbial diseases, such as schools, hospitals, stadiums, sports grounds and offices, and this approach may help to limit seasonal infections, the spread of tuberculosis and major epidemics.
