Do you believe surgical masks work during surgery? There’s “no evidence” they do this.

There’s also no reason that hearing there is “no evidence” for something requires you to adopt the silliest possible assumption for whether it’s actually true, but doctors seem to like doing this anyway.

(The actual answer for whether masks are “effective against covid” is “which covid?” - cause it’s different for 2020 covid and Omicron.)

The major conclusion to that discussion ("surgical masks work during surgery") was that the did work, but because they form an effective barrier against spittle and so on.

Studies show that surgical masks are only marginally effective at their goal of reducing transmission, and then only if they are worn properly. Of course, one can rely upon medical staff for that. Not so much the general population.
