FIGURE 2.

Inactivation of SARS-CoV-2 with Dulbecco’s Modified Eagle Medium (DMEM; positive control), 66.5% ethanol (EtOH), 0.5% sodium hypochlorite (NaOCl), 1% potassium monopersulfate (KMPS), 100 ppm chlorine dioxide (ClO₂), and 500 ppm ClO₂ during the Wiperator assay. Inoculated carriers were subjected to 5 s of wiping with disinfectant pre-soaked wipes infused with each of the examined disinfectants. Sterile uninoculated “transfer” carriers demonstrate transfer potential of viable virus to a clean surface through a used disinfectant presoaked wipe. All carriers were neutralized in 1 ml of a pre-determined neutralizer following indicated treatments, with subsequent viability testing in Vero E6 cells. Dashed lines indicate limits of quantification using the TCID₅₀ assay. Results represent the means of three independent experiments including three biological replicates each. Symbol *Indicates presence of viable virus in safety testing of a single biological replicate from the indicated treatment group.
