But UVC has been shown to be effective against SARS[1], so there is a good chance COVID-19 would also be affected. [1]: https://www.sciencedirect.com/science/article/pii/S016609340400179X https://www.sciencedirect.com/science/article/pii/S016609340... > The virus was inactivated by ultraviolet light (UV) at 254 nm > At 3 cm our UVC light source (254 nm) emitted 4016 μW/cm2 (where μW = 10−6 J/s) and the UVA light source (365 nm) emitted 2133 μW/cm2, as measured by radiometric analysis (Spectronics Corporation). After exposure to the UV light source, virus was frozen for later analysis by TCID50 assay using CPE as the endpoint. > Exposure of virus to UVC light resulted in partial inactivation at 1 min with increasing efficiency up to 6 min (Fig. 1A), resulting in a 400-fold decrease in infectious virus. No additional inactivation was observed from 6 to 10 min. After 15 min the virus was completely inactivated to the limit of detection of the assay, which is ≤1.0 TCID50 (log10) per ml. In contrast, UVA exposure demonstrated no significant effects on virus inactivation over a 15 min period. Our data show that UVC light inactivated the SARS virus at a distance of 3 cm for 15 min. So UVC would be indeed effective by these metrics. I kinda hope we can build something similar to disinfect laptops and cellphones at work, there are so many people touching those and taking the habit of flooding them with UVC before working on them or giving them back to a user would be a good step to reduce transmission.
