Great reminder, Laura - keeping hands away from your face is important. We have so many openings to our inner space via eyes, nose and mouth.
Wiping off the dance bar is a good suggestion. It reminds me, as I set off on a longish car trip, that I should use wipes on my steering wheel, gear shift and door handles too.
And while I'm thinking about it and writing this, the keypads on our electronics could use a wipe:
computers, ipads, iphones and telephones - especially mouthpieces.
