BIDA had seven reports of people testing positive after the 2022-05-01
dance, which was the last one before which we switched to requiring
N95/KN95/KF94/etc
<https://blog.bidadance.org/2022/05/requiring-high-filtration-masks.html>.
(Though a bunch of the ones testing positive carpooled together from ~2hr
away)

Dances with vax+mask policy I know offhand with no
reported spreads,
despite a culture of "please test if you feel ill, please tell us, and we
will tell dancers":
Greenfield, MA
BIDA, MA
Concord, MA
Downtown Amherst Contra, MA
Rainbow Contra in Western Mass
Pioneer Valley's ECD
Montpelier, VT (I believe?)
Glen Echo, MD
Pinewoods camp weeks that had this policy, at least masking and testing
for 3 days
Albany Contra, NY (I am pretty sure)
Portland, ME's new series
Unsure about CDNY, but I am pretty sure too.

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.
