I think they’re using CO2 as a proxy for air changes with the outside. (It’s tortured language, but there is underlying positive correlation between high observed CO2 from human occupancy and low air changes per hour and between low air changes and higher concentrations of other airborne contaminants.)

So I should keep the window open while I cough on my family? Not to shoot the messenger, but that's just PR to include things like virus during / after a pandemic.

That’s probably less unhealthful than to do that with the window closed.

I would expect that keeping windows open will decrease the risk of passing on an airborne disease to your family, yes.

My point was, if I am sick, and not isolating properly at home, it's not gonna make a difference, especially for something like covid.

Keeping CO2 levels low but I come and cough at the sofa and go will not make any difference.

Infections are a stochastic phenomenon, so while keeping your windows open won't protect your loved ones from you coughing on their faces, it may make a difference if you're attempting to isolate properly, or in other shared spaces.
