Effectiveness of 222-nm ultraviolet light on disinfecting SARS-CoV-2 surface contamination

•222-nm UVC light (0.1 mW/cm2) reduced viable SARS-CoV-2 by 0.94 log10 in 10 seconds.•222-nm UVC light (0.1 mW/cm2) reduced viable SARS-CoV-2 by 2.51 log10 in 30 seconds.•222-nm UVC light did not reduce SARS-CoV-2 RNA copy number after 5-minute irradiation.•TSID50 and not RT-qPCR should be used to m...
