Demonstrated SARS-CoV-2 Surface Disinfection Using Ozone

Abstract

SARS-CoV-2 has resulted in a global pandemic resulting in the infections of many millions and deaths of well over a million people. The ease of SARS-CoV-2 spread and the infectious nature of the virus in humans has resulted in an urgent need for effective disinfection strategies. Ozone (O3) is a promising disinfectant for SARS-CoV-2 due to its ability to overcome limitations with topical disinfection or sanitation products. In this work, we utilized RT-qPCR to measure RNA from a recombinant mammalian cell product, bacteriophage MS2, and SARS-CoV-2 sourced from municipal wastewater, after exposure to 4.5 and 9 ppmv O3.
