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?
