A lot of strong statements these days in support universal N95s, wearing 2+ masks. Models are great but can anyone point to a single epidemiological investigation consistent w numbers below (a 15-20% secondary attack rate when everyone is wearing surgical masks)?https://twitter.com/j_g_allen/status/1354382152830513154 …

(And this is yet another instance of why on earth do we not have better data? I mean, yes, cluster randomization for cloth masks for source control is hard, but I wish we had a randomized N95 study launched in Fall! We'd be on much firmer ground than this guessing game).

When we contact trace, nearly all infections happen during mask-less indoor contact. The variant is more transmissible but the physics have not changed, so masks still work. It makes more sense to get more people masked esp indoors, not adding more masks when you are masking.

I have a family member who may have had it, but had only been out of house once in two weeks. Did not go anywhere inside. Picked up food left outside for him. Spoke to no one. Two neg tests but if something caused fever/shortness of breath and Covid so prevalent here (LA CA)?
