Inactivation of SARS-CoV-2 on nine common healthcare facility surfaces by peracetic acid dry fogging. Surface coupons contaminated with 10 μL of virus inoculum were subjected to 1 h dry fogging cycle (N = 3 biological replicates per surface type) followed by elution in virus culture medium. No infectious virus was recovered from dry-fog-exposed coupons; viral titres recovered from the unexposed, dried positive control coupons of the same material type and quantified by end-point titration in Vero E6 cells are also shown. Dotted lines indicate limits of quantification for the TCID₅₀ assay. Results represent means of three independent experiments.
