Efficacy of an upper room ultraviolet-C (UV-C) technology versus far UV-C light technologies in reducing aerosolized bacteriophage MS2

In a room with 6 air changes per hour, an upper room ultraviolet-C (UV-C) and 2 far UV-C technologies were similarly effective in reducing aerosolized bacteriophage MS2 in comparison to no intervention. Both UV-C technologies could be useful adjunctive measures to reduce the risk for respiratory virus transmission.
