This is ridiculous. They either reduce droplets from flying around or they don't. If they do they should have some efficacy against any airborne respiratory virus. If they don't then why the **** have we been wearing them? Why are kids still going to school in them? Why the **** is this woman who has been on TV for two years just admitting this now? This makes me furious.
N95 even has limitations on aerosols…Anybody with more than 3 brain cells that works in medicine can tell you that an N95 mask, properly fitted, will reduce virus transmission through aerosolized particulate. The fabric masks, "dental masks", gathers, face shields...etc do NOTHING to prevent aerosolized particles. They never have and never will. That is what is so frustrating. Had Fauci, the CDC, the WHO all said from day one that everyone should wear an N95 mask, I would be right on board. The fact that medical professionals kept saying that "any mask" is better than no mask was total bullshit. Once you start lying to the public, don't be surprised when nobody believes anything that you say going forward.
Look, I specialize in gas particle testing, but i do a dozen or so particulate tests a year… even low micron quartz fiber filters have limitations… for small aerosols we have to run the air stream through liquid to trap it…
Large liquid droplets are easy to trap on material… when i was in the covid ward the stuff the people were wearing were much higher than p95/n95 stuff… a lot of the people were in p99 or p100 masks.. in the more severe isolation wards they had eye protection, wore disposable suits, and each room had a high efficiency air circulation system shuffling air out of the room constantly…
All things they downplayed telling us surgical masks with no fitted seal would do anything reasonable against an aerosol
