We can end the pandemic wearing N95 masks (respirators).

Yet another study using real-world data demonstrating that universal masking reduces transmission by *at least* 9-fold.

This would extinguish the pandemic.

Dr Richard Sear uses a conservative estimate of N95 filtering efficiency (90%). Real-world ‘exhaled breath’ data shows even better performance with non-fit-tested N95s: ~98%

which would then reduce transmission by a factor of 40

stopping the pandemic in its tracks.

Even universal masking using surgical masks (filtering out ~74% of virus) would reduce transmission by a factor of 3.5

which would (more slowly) extinguish the pandemic.

All we have to do is cooperate and work as a team for a few weeks.

(in other words behave like a civilised community willing to put in a bit of effort and resources for the common good)

… doing our part to end the pandemic, like this
