I just quoted the chair of UCSF School of Medicine stating covid was an aerosol and that he would be wearing a mask when in a room with anti-vaxxers.
Ergo, in his opinion, a mask must provide some measure of protection against covid as aerosol.
Anyone who's been paying any attention to the pandemic as it's unfolded will understand instantly that protection provided will depend on many factors. Fit and type of mask, size of room, how well the room is ventilated, # of people in the room, # of un-vaccinated people in the room, time spent in said room etc etc.
By your logic since we can't possibly know whom might be carring the virus, vaxed or not, we should in future avoid ever being in a room with another human being.
Ok, so in that quote of yours there is nothing where Dr. Wachter says it's an aerosol. Be that as it may, I will assume he knows this. However, part of my posts were about the delay in the general medical/scientific community of coming around to the idea that covid was an aerosol. To be fair, this may be more a fault with media reporting, but health officials have continually supported the wearing of masks without any strong support that they are effective.
As per your words in the above quote, "protection provided (by a mask) will depend on many factors", which goes back to my statements about the type of masks one wears and why they are wearing them. It also goes back to my statement about physical distancing and avoiding contact. That is contextual though. For example, prolonged contact in a crowded room with poor ventilation is going to present greater risk than walking past someone on the street where you're a few feet apart. So don't twist my words to fit your narrative. If you want to talk about sweeping and misleading statements, you should probably direct your attention to the way you interpreted my thoughts.
At the end of the day, the masks the vast majority of people are wearing are not very effective at blocking aerosols due to leakage from poor fit and permeability to aerosol particles. That's why I said unless you're wearing an n95 rated respirator or higher, the masks most people are wearing are not doing anything, especially in the context where you may be most at risk for getting infected - prolonged close contact in smaller spaces with ineffective ventilation. So places like pubs and restaurants (where people will have their masks off anyway) and are talking loudly and therefore potentially expelling more virus are going to continue to be potential hot spots.
And again, there is still no reliable data that shows that the masks the vast majority of people on the street are wearing offer any sort of measurable protection. If you go back to the early days, a lot of people getting sick were in places where they were in close contact with infected people and wearing masks that offer limited protection, surgical type masks or procedure masks, and not respirators. Respirators work, masks not so much.
I have faith in established science, until the story I'm being told starts to have flaws appear. With covid I thought hey, this is new so we have to go with best guess until we know better. There's been enough time that we now know better; that fomites present basically zero risk with covid, that covid primarily does not spread via droplets, that respirators can cause more damage than harm. There are other legitimate questions that are now time to answer or investigate more thoroughly as well. At the end of the day Covid is not probably going to just go away, it's here for good and we have to learn to deal with it. The actions of the past couple of years do not strike me as a means for humanity to live out the rest of it's days. It's time to realistically weigh the harms from covid against the cost to society from the measures we've taken to try and prevent it.
If you have some sort of evidence (research/testing/data) that shows cloth masks are effective in the prevention of the spread of covid or preventing people from catching covid please share. The words of Dr. Wachter are not that.
