Inactivation of SARS-CoV-2 by UVC light and hazardous to health.
The main goal of this joint project is to investigate the inactivation of SARSCoV- 2 and other selected respiratory viruses by UVC radiation of different wavelengths, irradiation doses, irradiation powers, bioburden, and humidity on inanimate and animate surfaces, i.e., healthy skin and oral mucosa. The focus is on the wavelength range of appr. 230 nm to 270 nm, for which the designations “near-UVC” (260-280 nm) and “far-UVC” (<240 nm) will also be used in the following.
Both the findings on virucidal efficacy and compatibility for humans and the development of UVC light sources are necessary prerequisites for numerous applications of the use of UVC radiation for the disinfection of sensitive surfaces, possibly for antisepsis and in particular for the decontamination of aerosols in recirculated room air (recirculated air) from air-conditioning systems, e.i. in public transport and air-conditioned rooms, as well as for room air decontamination in non-ventilated rooms by sucking the room air and recirculating it after UVC exposure.
