• Among them, UVGI, VHP, and moist heat treatment appear to be more effective and suitable for large scale decontamination of masks in the hospital setting, whereas moist heat, dry heat, and steam remedy may be carried out simply at home.
• They concluded that cotton, polyester, and polypropylene multilayered structures can meet or even exceed the efficiency of materials utilized in some medical face masks.

↵‡‡Alternatively, we now have additionally examined for pseudo-treatment effects in Jena over a interval of 20 d earlier than the introduction of face masks. This period is equally split right into a pre- and pseudo posttreatment interval. S11B exhibits, there is no sturdy deviation from the trail of the artificial control group. As for the case of placebo-in-house exams, it’s important for the validity of outcomes that we do not observe vital treatment effects for Jena previous to the introduction of face masks on 6 April or its announcement on 30 March.
