Inverse square law makes your idea not so practical, aside from the
inherent dangers of exposure to raw UV light!

Better to wash the room down with a disinfectant, or simply air it out
for a while...

If the person was very contagious then look up the procedures for
dealing with that rather than making up your own potentially dangerous
ones.
