UV Light is a disinfectant
Yes, but it isn’t that good for wiping out viruses on our skin, because it is highly damaging to our skin.
ANd it is so much easier just to use soap and water, which destroys the fatty layer protecting the virus, and then the virus quickly deteriorates.
I am using UVC in my air ducts now, mostly for mold/mildew on the coils, but it will also tend to destroy any virus that manages to get aeresolized.
