Been trying to unmask for half a year+ now and it's difficult, numbingly depressing, and extremely damaging to my reputation (in places that do matter, not just pointless social status standing)
The end of the tunnel leads to a beautiful forest full of life and light though right?
I said an N95 is effective by itself yes
That study only shows efficacy of masks at preventing COVID 19 particles penetration
I'm talking about efficacy of preventing COVID while being the only one masked in a crowd of unmasked
Masked surgical gives you an upper bound of 90% chance risk of infection with only one other unmasked person. N95 gives you a 20% with only one other unmasked person

Look, I support masking and like I said, I would love to wear one if most others would also wear one. I was wearing a mask by my lonesome for months after quarantine ended
Listen comrade. A one off study should not put set against a systematic review (see Wikipedia's guidelines for medical sources). If you want to be helpful, don't make controversial statements about medicine, in which wrong information could get someone hurt or killed.
