UK: What if everyone had masked up? Analysis of app data has the answer: "Respirators would have dropped the rate of COVID transmission by an estimated factor of 9, compared with 0.6 for surgical masks. A factor of 9 is enough to put SARS-COV-2 into exponential decay! www.nature.com/articles/d41...

To check. This means N95 masks? "Respirator" sounds like a piece of medical equipment, not a mask?

Mask are medical devices designed to prevent the surgeon to spit into the sound during surgery - you call them blue baggies, regulated under FDA / GDPR. Respirators are designed for aerosol prevention and regulated under NIOSH or FFP2/FFP3

As result the virus would have been highly suppressed for as long as respirator use continued buying us time to find a solution to eliminate it Well we decided that we prefer throwing children under the bus and adults in front of trains

And not just COVID! There is ample evidence that it would have significantly damaged - if not eradicated - other related airborne viruses and bacterial problems, e.g. flu hospitalisations AND deaths dropped significantly when masks were worn.

Germany required FFP2 at some point in public transportation. But too many riots from people who claimed that Covid was just a cold to them. So now everyone has to risk their health if they want to travel on the train or bus.

We achieved local elimination early in Aust & NZ saving thousands of lives. And that was without the knowledge of transmission we have now or widespread use of P2/N95 respirators. Then rich people didn’t want to give up international travel or wear masks so here we are 🤦🏻.

What if everyone masked up *now*? At least in crowded indoor spaces? And *definitely* while sick? What if we enabled sick people to stay home and rest?

We could eliminate not only COVID but also flu and the common cold, save thousands of lives every year, vastly improve quality of life for everyone, *and* hugely reduce exposure to airborne allergens and microplastics. It's time to take air hygiene as seriously as drinking water safety.

Back then (or even now), this would significantly slow the process of variant evolution, further slowing the population spread, with more sustained immunity and fewer reinfections. Targeted use could further protect IC folks, as chronic infections have been the source of all major variants.

I don’t remember anyone even talking about or advocating for “respirators” until late 2021. Even today most of the “mask” people tend to use surgical ones (and as your analysis points out, they’re almost useless for airborne pathogens).

Everyone I know who masks is wearing n95 or equivalent, like this, which is a respirator.

An n95 particulate respirator - a mask designed to cover the mouth, nose, and chin, with two straps to connect it over the back of the head.

There was a serious shortage in 2020. They used the lie that masks do not work to keep FFP3s for healthcare workers (and then even did not give those masks to healthcare workers for some reason). And they could not abandon the lie in 2021 when there was enough supply.
