Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?

At least as long as human beings have lived in large, close groups, respiratory viruses have been present — sometimes an annoyance, sometimes a catastrophe. Though we’ve managed to create vaccines and drugs to blunt their effects, the viruses endure.
But there is a group of people who think we do not need to live this way. These scientists, activists, and entrepreneurs believe we’re going to look back on this era, one of commonly endured airborne infections, as a case of antiquarian barbarism, a bunch of needless suffering that we accepted because we didn’t know any better. They believe that we have the technology now, and will have even better technology soon, that could end respiratory infections for good, the way that disinfecting our drinking water with chlorine helped end typhoid as a major cause of death in the US.
The technology is called germicidal ultraviolet light (GUV), and in particular, a relatively novel kind of ultraviolet light often denoted as “far-UV.” “We have so much data suggesting that this is far and away the most impactful technology, when it comes to protecting people from infectious disease, that exists today,” says Kevin Esvelt, a professor and biologist at MIT who has championed the idea.

When Trump mentioned the disinfectant properties of UV, people started drinking bleach apparently. Similar to confusing HCQ with aquarium cleaner.

Think of it as evolution in action.
