Interesting medical papers.
But I would rely more on my own experience on substances spread around apartment block.
When our Indian neighbors fire up their aromatic/smoky/sandal wood sticks it's immediately stinks in our bathrooms and on lift lobby.
So if anyone gets sick in the building I would physically cut off any ducted air communication going into apartment
However you are comparing apples and oranges, or in this case apples and grapes.
With coronavirus aersol transmission the aerosol is the
virus attached to a water droplet and there is a limit as to how far that can droplet can travel. It can be across a room for the smallest droplets, but with the larger droplets it is more problematic within 1- 2 m. The smallest droplets are
5 micrometers and remain airborne longer than the typically larger ones and may reach across a room.
Infectious virus in aerosols are rapidly diluted through ventilation and natural decay in the environment, it is likely that the greatest risk of aerosol transmission is in close proximity to infected persons.
Whereas particles from smoke tend to be very small -
less than one micrometer in diameter. As they are generated by a heat source they also tend to be bouyant and so spread and remain for hours if not longer. The presence of smoke spread is not an indicator for aerosol transmission.
The case with SARS was effectively powerful fan fans blowing blowing across a room, and people being present within that room. So yes do not remain in a room with a virus source and fans blowing (or even without fans blowing).
With AC in a building the air will be drawn some distance to the heating/chilling unit and then returned that distance again. So if this is so in your apartment cutting off your AC would do nothing.
Now in an apartment block you may have line of sight open connections through open windows or doors. So yes you would want these to be more than an adjacent room. But unless an infected person was coughing at the window or under the door transmission risk would be low.
