What is your definition of "work"? Of course better ventilation won't outright stop diseases from spreading, the point is that it will reduce the spread with reasonable cost and little downside (like another commenter mentions, if the existing ventilation isn't keeping up with CO2 concentrations, there can be other benefits).

From what I saw with our schools.... it didn't really cut the spread. Estimates are that the school had just as high of spread as elsewhere. And that is with near 100% vaccination of the kids in said school. I should note I'm not against trying. It seems a low hanging fruit to reach for. Just, evidence has shown that this particular disease goes for saturation fairly effectively.

  Which evidence? You just quoted absolutely zero evidence beside your own personal anecdotes. It's an airborne disease. Better aeration definitely helps with airborne diseases, multiple studies prove it. https://pubmed.ncbi.nlm.nih.gov/17257148/ https://pubmed.ncbi.nlm.nih.gov/17257148/ But of course, COVID spreads so easily that this can reach the limit (especially Omicron) and in an environment where kids will interact together in all kind of ways, but this would have definitely helped a lot more in the first few waves (pre-omicron) without needing to shut down schools entirely.

    The personal evidence of my kid's schools. Three kids, three schools. So, yeah, small N. I'm confused on the particular study you picked. The main claim for positive evidence "supports the use of negatively pressurized isolation rooms for patients with these diseases in hospitals" but it goes on to basically acknowledge we still need more information in larger environments. Specifically, in the abstract, "However, the lack of sufficient data on the specification and quantification of the minimum ventilation requirements in hospitals, schools and offices in relation to the spread of airborne infectious diseases, suggest the existence of a knowledge gap." I'm all for more studies. And, again, I expect and hope we learn more.

    There was never any need to shut down schools at all. Some countries such as Sweden left primary schools open throughout the pandemic (without mask mandates) and they did fine.

      That does bring in an interesting case to look at to try and counter my point. If I am right that schools were one of the largest vectors of all of the other sicknesses that have been heavily suppressed in the past couple of years, than I would expect that in Sweden this suppression was not as pronounced. Any chance you know of where to look for that data?
