    55 cases out of 81 people attending exercise classes at a gym, despite 6-ft distancing and some mask use. Ventilation was not assessed.https://www.cdc.gov/mmwr/volumes/70/wr/mm7009e2.htm?s_cid=mm7009e2_e …

        Good. Should not assume ventilation because my local community center/gym unplugged all the fans, etc. “Some mask use” is just America!®

        Here was my original thread tracking the case counts going up up up. https://twitter.com/jmcrookston/status/1316747588016771073 … @linseymarr had posted about SPINCO, my thread spun off hers. (See what I did there?)

        Keep all "indoor" gyms closed [weather permitting, widely spaced exercise equipment outdoors far/FAR less risky, and ought to be allowed]

        Had this discussion before. Ventilation in almost every US bldg is designed so that it will spread germs from a "super-spreader" across a large number of people before getting to the return duct. Unlike airplane ventilation. No great surprise here. Just like the Korean office.
