There have been a large number of studies that have looked at the risk of infection and ventilation. If someone is infected and secreting virus in an enclosed space, the amount of virus that anyone else is exposed to will increase rapidly. Good ventilation effectively dilutes the amount of virus in the air, it also reduces C02. These are really, simple correlations that provide no real evidence that the C02 is anything more than a proxy measure of ventilation. I can't even figure out why or indeed how these have been published.

This is why building codes use CO2 concentration as a proxy measure for contolling required ventilation.

Not quite what the article finds.

The study used artificial air in a lab setting and varied the CO₂ concentration. They found that the virus was suppressed when the CO₂ concentration was <=500ppm, versus the 'well ventilated' room concentration of ≈800ppm.

See the article for details.
