Social-distancing guidelines to stay 6 feet from others may be woefully inadequate, one scientist warns — saying the coronavirus can travel 27 feet and linger for hours. MIT associate profess…

Yeah, saw an alert about that. Good point.
It is NOT safe to be 2 metres from a sick person, who would want to do that?
The guidelines are minimal basic security that just
improve risks, and reduce infection rates.
Thing is we need an infectious
dose of virus particles in theory- which could be millions of them, IDK, - to likely cause a clinical infection. One virion particle is not a threat by itself in general is what they taught us. That is astronomically different to a single mucus droplet, which is like an ocean swimming with fish.
IRL, where are you going to really find just one virion? It's going to be droplets.
Can exposure to a single virus particle lead to infection or disease? Until now, solid proof has been lacking. Experimental research with insect larvae has shown that one virus particle is theoretically enough to cause infection and subsequent disease.

But this caterpillar study says different.
One virion seems to cause the whole illness. This isn't the same as saying if one gets in our nose we have had it. Odds still get worse the bigger the number of the dose. At some tipping point, a single one starts to replicate and BOOM We-We-We are Borg.
It is analogous to getting hit by shotgun blasts. One pellet
could kill, but the whole cluster is a much worse deal. The whole cluster is one barely visible mucus droplet.
So wearing masks works mainly not by filtering your intake but by blocking the
output from asymptomatic carriers. Still, I am wearing that if I go in public.
