Ok. After doing some research in figuring out what the press briefing was about. I was pointed to this article.
https://news.columbia.edu/ultraviolet-technology-virus-covid-19-UV-light
The technology, developed by Columbia University’s Center for Radiological Research, uses lamps that emit continuous, low doses of a particular wavelength of ultraviolent light, known as far-UVC, which can kill viruses and bacteria without harming human skin, eyes and other tissues, as is the problem with conventional UV light.
That’s basically the important paragraph. Seems interesting as I had not heard about it. They are in production and awaiting FDA approval and cost $500 - $1,000. I couldn’t find a picture of it but I hope it doesn’t look ugly.
Please don’t swallow UV lightbulbs to cure coronavirus.
