Is there any research on the effect of UVC on eliminating or preventing SARS?
We are not aware of any research that has been done on this pathogen. However extensive testing has been done over the years that proves the effectiveness of germicidal UV (UVC) against a variety of infectious organisms. There is also a wealth of anecdotal evidence of significant reductions in infection rates in occupied spaces when using UVC in air-handling systems. We know of several scientific studies that document the effectiveness of UVC on fungal and bacterial contaminants. Since SARS is a virus and viral particles are very small (normally between .75 to .01 micron diameter), much smaller than fungal or bacterial particles, they should be much more susceptible to UVC energy, even when attached to droplet nuclei, as in a sneeze or cough. SARS is thought to be spread by direct contact and by inhalation. UVC lights in an air-handling system would eliminate only the airborne particles. Even so, properly designed and installed UVC light systems will reduce the overall numbers of patho
