I know we all hate them, but some dances are still requiring masks.  Has there been documented spread at a dance where everyone is in a (K)N95 or better, like a Breeze 99?  How about vax+mask or vax+test+mask?  I think we all know that vax+test-mask=spread, from numerous events this past summer and since.

I'd also be interested in a professional opinion on whether our gyrations mean anything if we're not also masking full time when we're out and about.  I know the theory, dance is more breathing and close up for a long time, but the new variants are so infectious that I wonder if that matters.  If you're getting 10x the infectious dose in the grocery store, protection during a dance wouldn't matter much.  It's like locking the doors and leaving all the windows open.  But, maybe it's 0.1x the infectious dose at the grocery, and our measures do matter.  I'm only interested in data, not speculation.  Does anyone have any?

My wife got covid at Roanoke Railroader last summer and I got it from her.
I researched then (so relevant to variants then, not necessarily current variants)
and most transmission occurs 1 to 2 days before testing to 2 to 3 days after testing.
I don't know if that is relevant to this discussion because ...
I assume most people test when they start to feel different from normal health ...
which might explain the "1 to 2 days before testing" transmission
and that's different from a "test regardless of how you feel to dance" testing policy.
But, I do not know that. That just happens to be the data.

Turkey Quicky, a mini-weekend, fortunately escaped covid spread though
someone tested positive Saturday morning after dancing Friday night.
(most dancers were unmasked)
A KY weekend dance before TQ had a roughly 20% covid
spread with a recent negative test and a negative test on entry policy.

I'm not saying what policy should or should not be enacted to
prevent the spread of covid. I'm just noting one official statistic
and two recent weekend dances data points.
