No.

People point to countries that had successful anti-covid work and use of masks, but they're missing all the other work those countries did around social distancing and track and trace.

- DanBC 6y agoBut we have evidence about respiratory viruses and masks, and it all says they don't work. We even have the beginnings of evidence coming through for SARS-CoV-2. They got people who have covid to wear a mask and cough on a petri dish. Covid escaped the masks.
- ceejayoz 6y ago> But we have evidence about respiratory viruses and masks, and it all says they don't work. What? Medical personnel regularly utilize surgical masks against respiratory viruses spread by droplets successfully. They're less useful against aerosolized stuff like measles, but SARS-CoV-2 is primarily spread via droplet.
