Let's cut to the chase. If the goal is to sanitize a former sickroom of potentially dangerous and/or persistent bacteria and viruses, using effective means-and-methods as economically as practical, do so with established materials following established procedures and protocols.

Otherwise, it is just speculation and baseless opining.

NOTE: I work in, but not for a major medical school and in their major research and teaching facility. Animals, BSL-3 labs, and all that. Cleaning is a serious concern as on any given day, there is about $30,000,000 in research happening within the building. This building also happens to be attached to a major hospital that closed in November. Where, again, cleaning was a serious business.

Guys and gals, UV is in use - but only in very specialized applications. Otherwise, it is too slow and far too dangerous. Around the animals, it is mostly alcohol and dilute bleach. In the patient rooms it was a mix of alcohol-based wipes and solutions together with various sanitary wipes using complex molecule germicides. BUT, for any sort of spill of patient fluids, blood or similar, it was bleach. Good old bleach. Kills everything, and is easily removed when done.

Ah, well. I guess it MUST be the hard way.
