Decontamination of common healthcare facility surfaces contaminated with SARS-CoV-2 using peracetic acid dry fogging

SummaryBackground The SARS-CoV-2 pandemic has highlighted the urgent need for safe and effective surface decontamination methods, particularly in healthcare settings. Aim To evaluate effectiveness of peracetic acid (PAA) dry fogging decontaminating facility surfaces experimentally contaminated with SARS-CoV-2. Methods Nine materials (stainless steel, latex painted wood, unsealed hardwood, melamine countertop, vinyl flooring, clear plastic, faux leather, computer keyboard button, smartphone touch screen) were >106 median tissue culture infectious dose (TCID50) SARS-CoV-2, allowed to before exposing PAA fogging. Findings When fumigated fog 1 h, no virus was recovered from any inoculated types. By contrast, high titres corresponding untreated drying controls same materials. Conclusion Standard processes, including sprays wipes, are laborious frequently cannot completely decontaminate sensitive electronic equipment. ease use, low cost, overall a suggest that it should be considered settings, intensive care units where severely ill patients cared for.
