The goal of this white paper is to examine the benefits and risks of using Germicidal Ultra Violet (GUV) light systems in fighting the transmission of infectious diseases. These systems have been used for over a century in water treatment, air systems, and for disinfecting surfaces. GUV has been most commonly used in hospitals, pharmaceutical, manufacturing and clean room applications. It is a proven technology for disinfection and killing of viruses, bacteria and fungal organisms. GUV is becoming increasingly well known to the general public due to the COVID-19 outbreak.
