This work focuses on the usability of Ultraviolet (UV) on humans as an economical way of contesting against COVID-19. Specifically, far-UVC is presented as a promising candidate against COVID-19 since it can inactivate pathogens including viruses and bacteria without harming mammalian skin or eyes. Furthermore, the work also points out the applicability of far-UVC lights for public spaces and treatment of selective region in COVID-19 patients by using fiberoptic as the medium for high-risk cases where chances of survival are low and such treatment may avoid fatality due to the COVID-19.
