Executive Summary : | Protective respiratory face masks protect the nose and mouth of the wearer from vapor drops carrying viruses or other infectious pathogens. However, incorrect use and disposal may actually increase the risk of pathogen transmission, rather than reduce it, especially when masks are used by non-professionals such as the lay public. Copper oxide displays potent antiviral properties. Impregnation of copper oxide into respiratory protective face masks may endows them with potent anti-COVID 19 properties without altering their physical barrier properties. |
