Fast and easy disinfection of coronavirus-contaminated face masks using ozone gas produced by a dielectric barrier discharge plasma generator	2020-05-01		.txt	text/plain	800	46	59	title: Fast and easy disinfection of coronavirus-contaminated face masks using ozone gas produced by a dielectric barrier discharge plasma generator In this study, using a human coronavirus (HCoV-229E) as a surrogate for SARS-CoV-2 contamination on face masks, we show that the virus loses its infectivity to a human cell line (MRC-5) when exposed for a short period of time (1 min) to ozone gas produced by a dielectric barrier discharge plasma generator. Similar results were obtained for 117 face masks experimentally contaminated with either influenza A virus (H1N1) 10 (Table S1) or 118 Gram-positive bacteria Staphylococcus aureus (Table S2 and Figure S1) when exposed to 119 ozone gas. These results suggest that virus and bacteria on face masks can be inactivated by 120 ozone gas at a concentration of about 120 ppm within a short time (1-5 min). The result showed that the repeated exposures (5 times) 161 of face masks to ozone gas did cause structural damage to the face masks.	./cache/cord-289778-x938errh.txt	./txt/cord-289778-x938errh.txt
