I tried looking into that this spring. I suspect the answer is for this virus not much. Nothing to indicate that any part of it's life cycle involves hanging around latent. Interesting bit on how UV-C works to sterilize. https://en.wikipedia.org/wiki/Pyrimidine_dimer https://en.wikipedia.org/wiki/Pyrimidine_dimer Interesting thing bacteria and some viruses have DNA repair enzymes that can fix damage from UV-C. Medically you're always bedeviled by bacterial and fungal spoors. Limitations with UV-C sterilization I think prevents wider use. Not a magic bullet. Though it probably works well for influenza, colds, and this bat virus.
