I’ve noticed an uptick in students wearing masks in class (I teach at a university). Definitely a minority, but up from near-zero to now maybe 10-20%. Unlike previous waves, the university administration is studiously avoiding mentioning covid at all, and not recommending for or against anything, so it doesn’t seem to be driven by top-down policy decisions.
I don’t see as much of that as I did back when the university required masks. The students wearing masks now seem to be a self-selected subset who are more worried about covid than average.
I do see a decent number of surgical masks (vs N-95s). For me personally I would either wear something with good filtration or not bother, but I guess others disagree.
Double masking with surgical has been shown to get to 80% filtration efficacy because of better sealing. That said, there are brands of N95 mask that are more comfortable and easier to be heard through than a two-mask layer.
