        It seems there is not an actual paper with the details available yet, correct?

        I've been worrying about this when I go out on my runs. Have been trying to stay really far from folks so I don't breathe heavily in front of them. Tried running with a bandana mask-- was hard!

        I suspect your consideration makes you the exception. The majority of runners seem to think that, because they're moving at speed relative to walkers, the 6ft / 2m rule doesn't strictly apply to them. Same goes for cyclists.

        Ah, thankfully they’ve added citations and names. The initial version on Medium cited no one so it was sketchy.
