Anti-sars-cov-2 activity of surgical masks infused with quaternary ammonium salts

Abstract

The SARS-CoV-2 pandemic has highlighted the need for protective and effective personal protective equipment (PPE). Research has shown that SARS-CoV-2 can survive on personal protective equipment, such as commonly used surgical masks. Methods are needed to inactivate virus on contaminated material. We show here that embedding viral-disinfecting compounds during the manufacturing of surgical masks inactivates a high dose (up to 1 × 105 pfu) of live, authentic SARS-CoV-2 within minutes.
