We do know that coronavirus can be spread by exhaling. But I haven't seen any real world testing that actually quantifies it. Laboratory testing under controlled circumstances there are plenty of. The case that really caught my attention happened in Mount Vernon, Washinton. Article attached.
56 choir members attended practice. Where they were singing, exhaling forcefully. 45 of those in attendance were diagnosed with Covid-19. At least 2 of them died. Tracing confirmed choir practice as the common denominator.
But how does that compare to walking down the aisle of a Walmart or watching your grandkids play at the park?
Just something to think about.

Interesting . . . social distancing didn't help them apparently. Having been in a few choirs I'd be surprised if a few folks weren't spitting while singing. Definitely needs more research though IMO.
Thanks.
As far as how choir practice in a confined space compares to walking down the aisle at Walmart or playing outside goes . . . I'm going to venture to guess that it probably doesn't.
