The study is compelling but I don't think anyone cares about COVID-19 anymore. Nor do I think you'll ever get kids to care enough about masking to do it properly.
Children and the general public may not care, but there's still plenty of analysis that will prove useful to medical and policy decision-makers in the future.
And here I am with a family of 5 who are all home sick with covid right now. :)
i.e., not dead i.e., not hospitalized
Different class of problem ;)
When someone is sick enough that they ought to stay home, but they go somewhere indoors anyway and wait around for a while, where is it? Likely a health care facility. And there are tons of nasty, often drug-resistant, pathogens that are largely transmitted in health care facilities. And a lot of people visitng said facilities are also vulnerable and/or immunocompromised and/or are taking medicines (e.g. antibiotics) that substantially increase the risk of getting infected by otherwise-not-so-harmful things.
So, please, bring on the infection control measures in health care facilities. Masks, air filtration, ventilation, far-UVC, hand washing, sanitizer, you name it.
