Snippet: Regarding disinfection, NIOSH guidelines [3] advise to discard masks after aerosol-generating procedures. However, previous studies have shown that UV disinfection is suitable to remove viral load although more studies are needed to acscertain viral removal from the inner FFR layers. UVGI dose for coronavirus in surfaces has been shown to be lower than other types as they're single-stranded RNA virus. For example, Duan et al [7] found that 0.32 J.....
Document: Regarding disinfection, NIOSH guidelines [3] advise to discard masks after aerosol-generating procedures. However, previous studies have shown that UV disinfection is suitable to remove viral load although more studies are needed to acscertain viral removal from the inner FFR layers. UVGI dose for coronavirus in surfaces has been shown to be lower than other types as they're single-stranded RNA virus. For example, Duan et al [7] found that 0.32 J/cm2 can inactivate SARS-CoV in culture plates, whereas for H1N1 influenza, decontamination with 1.2, 1.8 or 1.98 Joules/cm2 achieved an average 4-log reduction of viable H1N1 influenza virus [1, 8, 9] .
