We Need to Reckon with the Aerosol Spread of Covid-19

A group of people indoors, without masks, breathing heavily, over long periods of time in what I’m guessing is not a properly ventilated room — this is exactly the sort of thing that has been shown over and over again to be problematic.

The science is there, but governments and public health agencies have not caught up with this yet. If you take the transmission by aerosols into account, the rules for gyms (and bars and restaurants) being open is that they should probably not be open at all — or if they are, they should be well-ventilated and the wearing of masks should be mandatory at all times.
