Experts are working on a new type of ultraviolet light called far-UVC that could be highly effective for reducing airborne transmission of diseases such as COVID-19 and influenza--as well as surface contamination in hospitals--with hopes that it could even reduce the risk of the next pandemic.

New UV air disinfection technology could help protect against health care infections, possibly the next pandemic in Barcelona, Spain , Dr. Curtis Donskey from the Louis Stokes Cleveland VA Medical Center in Cleveland, Ohio, U.S., will discuss the efforts being made to develop this continuous surface and air decontamination

"Compounding the problem, and a major limitation of traditional cleaning and disinfection strategies, is that disinfected surfaces rapidly become re-contaminated between manual cleaning episodes," explains Dr. Donskey."Daily cleaning of patient rooms is likely to be inadequate to reduce the burden of infectious pathogens, and manual cleaning of intricate surfaces, equipment, and devices makes thorough cleaning difficult.

Far UV-C has a shorter wavelength than conventional germicidal UVC light and cannot penetrate or harm skin, eyes or tissue. Studies have shown that far-UVC light can kill the SARS-CoV-2 virus, other human coronaviruses, influenza, and drug-resistant bacteria quickly and efficiently. Based on the information currently available, the US Centers for Disease Control and Prevention has stated that in the near term, whole-room UV is best viewed as new and emerging technology.
