Wouldn’t it make sense to install UV lights in bathrooms? Over doors and possibly on door handles? I’ve seen wearable UV lights, but I don’t see it being worn by frontline personnel.
We have seen social distancing indicators, plexiglass dividers and masks become commonplace. I feel like UV light should also be more commonplace, but it isn’t. Why not?

It’s not just any old UV light, there are specific wavelengths of ultraviolet that are detrimental to microbes and viruses. But those wavelengths are also pretty detrimental to humans. So it’s not really a good idea to bathe people in those lights all the time. There are ways of passing air through ducts that have those particular UV lights installed, and that air gets sanitized, at least somewhat, without exposing people directly to the UV. Another problem is that the UV exposure has the last for more than a few seconds, so in those duct systems they generally need a nice long run of ductwork where there is UV lights installed to give the air enough time under exposure. And then of course there’s additional expense associated with the sanitation grade UV lights, that are much more expensive than typical light bulbs and UV lights you can pick up for a few bucks from Amazon. That said, people are working on really clever ways to get the benefit of UV exposure with less risk.
