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 …

Fair points all around, though still seems the fundamental issue is ppl not wearing any mask at all, not that people aren't wearing N95s. Maybe the ship has mostly sailed on that one.

Jury is out on new variants, but if transmissibility difference is viral load mediated Id be surprised to see meaningful clinical difference beyond surgical masks given basically no epi evidence of transmission w surgical masks & wild type.
