UVC has been used for many years for sterilising.It is now entering into more places such as hotel rooms.
Ever since the outbreak of COVID-19, the travel industry has suffered badly, with some hotels’ occupancy in Hong Kong reaching as low as a single digit a day. With significantly fewer guests at...

And this article from the BBC.They couldn't help doing a little Trump bashing at first but later some science.
"There is also a third type: UVC. This relatively obscure part of the spectrum consists of a shorter, more energetic wavelength of light. It is particularly good at destroying genetic material – whether in humans or viral particles. Luckily, most of us are unlikely to have ever encountered any. That’s because it’s filtered out by ozone in the atmosphere long before it reaches our fragile skin.
Or that was the case, at least, until scientists discovered that they could harness UVC to kill microorganisms. Since the finding in 1878, artificially produced UVC has become a staple method of sterilisation – one used in hospitals, airplanes, offices, and factories every day. Crucially, it’s also fundamental to the process of sanitising drinking water; some parasites are resistant to chemical disinfectants such as chlorine, so it provides a failsafe.
Though there hasn’t been any research looking at how UVC affects Covid-19 specifically, studies have shown that it can be used against other coronaviruses,
such as Sars. The radiation warps the structure of their genetic material and prevents the viral particles from making more copies of themselves."
"Nevertheless, a concentrated form of UVC is now on the front line in the fight against Covid-19. In China, whole buses are being
lit up by the ghostly blue light each night, while squat, UVC-emitting robots have been
cleaning floors in hospitals. Banks have even been using the light to
disinfect their money. "
There’s only one type of UV that can reliably inactivate Covid-19 – and it’s extremely dangerous.
