The complex job of modeling can be as complex as fluid dynamics but we are not there yet. All we have that works is HIDE.

The behavior of this infection is maddingly variable.

It is like an FBI profiler only able to identify a serial murderer as someone who murders.

At this point statistics is still almost meaningless. It will be years before the patterns will reveal its secrets.


In an airborn virus think of a smoker inside by a sunlight illuminated window. The light makes the smoke more visible. Watch the behavior of the smoke. It doesn't stop at 2 meters.

By Occams Razor my opinion is that one factor may be that a threshold exists that a sufficient viral density is met for serious infection.

Sensing the existence of cigar smoke is different than it making you choke in a cloud of smoke.
