In Vitro study showing undiluted PVP-I (1% w/v) achieved >5 log10 reduction in SARS-CoV-2 virus titres at 15, 30 and 60 seconds treatment exposure under both clean and dirty conditions. In contrast, when PVP-I was tested at 1:2 dilution a >4 log10 kill at 15 seconds and >5 log10 kill at 30 and 60 seconds in comparison to control was seen in both clean and dirty conditions.
