Anti-SARS-CoV-2 Activity of Surgical Masks Infused with Quaternary Ammonium Salts

Viruses. 2021 May 22;13(6):960. doi: 10.3390/v13060960.

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.

Keywords: SARS-CoV-2; inactivation; masks; personal protective equipment.
