Because doing that is stupid. Bullets can kill viruses too if they hit them dead on, why don’t we have them everywhere too? Just in case.
Wow, a lot in this. Thanks for posting!! I want to watch progress in this area, as it’s exciting to think that, indeed, URI cases could be significantly reduced in number and severity with the right measures. In my clinic we opted to use multi-stage HEPA filters in each room, and space patients such that the air circulates thru the filters sufficiently between patients. Everyone is also masked.
Those NFT losers had a similar idea, and while it may have burned their eyes and skin it’s probably the closest they’ve ever come to a shower.
Because it also breaks down everything else, like plastic, wood, your skin, your DNA, and then you have cancer.
Because we have skin and eyeballs?
Doesn’t explain why we don’t use them to sanitize rooms while we’re not in them.
What does explain it is that UV also damages stuff too. You use it to sanitize your living room, and soon the fabric on your couches will start losing their color. The paint on your walls will start flaking off. The plastic frames of the frames on the wall will start crumbling away or turning sticky. Nobody wants that in their house.
UV is used to sanitize stuff when people aren’t around but yeah, it does damage a lot of materials so that’s a pretty limiting factor. I’ve seen them used inside air circulators to kill bacteria for over a decade too (usually in hospitals and restaurant kitchens).
