Deep ultraviolet light (UV) is useful for the disinfection of microorganisms, including bacteria and viruses. Although genome damage by UV has been widely accepted, adverse effects on activity and/or function viral proteins envelope components are poorly documented. Worthy note, observed unfavorable UV-effects viruses only insufficiently analyzed in association with reduction infectivity. In th...
