Please show us the relevant paper and then show the link between that paper and changes in policy, because I've never heard of such a paper and nor has anyone else who investigated where this sudden change in mask policy came from. Reality is, respiratory viruses and masks have been around a long time. There was very little that was novel about SARS-CoV-2 despite attempts to claim otherwise, and prior understanding was correct: masks did nothing and that's clearly visible in the data. They were forced on everyone for political and ideological reasons, not scientific ones. >> given that quarantining everyone wasn't an option. It wasn't!? Because lockdowns sure seemed like quarantining everyone to the rest of us!
