Residual antimicrobial coating efficacy against SARS-CoV-2.

ABSTRACT:

Aims

This study evaluated the residual efficacy of commercially available antimicrobial coatings or films against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on non-porous surfaces.

Methods and results

Products were applied to stainless steel or ABS plastic coupons and dried overnight. Coupons were inoculated with SARS-CoV-2 in the presence of 5% soil load. Recovered infectious SARS-CoV-2 was quantified by TCID50 assay. Tested product efficacies ranged from <1.0 to >3.0 log₁₀ reduction at a 2-h contact time. The log₁₀ reduction in recovered infectious SARS-CoV-2 ranged from 0.44 to 3 log₁₀ reduction on stainless steel and 0.25 to >1.67 log₁₀ on ABS plastic. The most effective products tested contained varying conce
