I thought this same thing up until about a week ago. Can you post sources of studies that show that the bolded part is true? There seems to be a lack of evidence for this line of thinking and is exactly why the Surgeon General was initially saying masks do not work. I thought he was incorrect at first but it appears the guy actually knows what he's talking about.

Here is a link to an article that talks about some current research. The conclusions are that masks really don't do much of anything.

I haven't read the article or studies, but it just seems like anything that is used to cover the mouth / nose area would have some impact on the amount of particles and distance they're traveling when you breathe out. This just makes sense to my mind.

Same thing I thought. Recent studies show otherwise. Although there are mixed results.
 
Meta analysis of mask effectiveness. Didn't appear to help much against viruses. From 2017 but very robust.

Effectiveness of Masks and Respirators Against Respiratory Infections in Healthcare Workers: A Systematic Review and Meta-Analysis

In this systematic review and meta-analysis, we found evidence for a protective effect of facemasks and respirators against clinical respiratory infection among
academic.oup.com academic.oup.com

"There was no significant difference between N95 respirators and medical masks in protecting HCWs from SARS (OR = 0.86; 95% CI: 0.22–3.33), with corresponding RRs of 0.88 (95% CI: 0.26–2.27) and 0.94 (95% CI: 0.41–1.34) under baseline risks of 20% and 60%, respectively..."

If this is what they found do we really expect homemade cloth masks to be better?

This is still prevention from getting sick and not the other way around though.
 
Getting dinner ready tonight and discovered we were out of ranch dressing. Boogie up to the dollar store since it's the closest. 5-6 customers in there and 2 employees. I was the only one with a mask on. I was kinda shocked the employees didn't have one. This made twice I had to leave the house today....I don't remember the last time I left the house twice in one day. Not a fan of it.

I also want to point out that how likely is it that someone was able to find a bat coranavirus that had significant homology rather quickly unless it had already been identified and that particular coronavirus was already sequenced? Same thing with the pangolin.

How likely is it that they randomly started looking for coronaviruses in the wild and ran across a "new" bat coronavirus in a couple of months? Even less likely someone would decide to test a pangolin for a coronavirus and then miraculously found it would be 99% similar to Sars 2.

These had to be known coronaviruses to have those sequences to even compare them.

The big question is were either of these similar reservoir coronaviruses used in gain of function research?

There was an article a few months ago that said that a scientist that worked for one of the labs in Wuhan who's job was to find bats that that had previous unknown virus infections. (the Bat Lady was her nick name), It said that she brought back some Horseshoe Bats whose nearest colony was 500 miles away for study by scientists at that lab. She has since disappeared and so has most if not all of the lab techs. The article also said that no one remembers seeing a horseshoe bat in a Wuhan wet market. I believe that someone in that lab got infected and (unknowingly) and passed it on by either going to the market or passing it on to a family member that went there.
 
Whew. I was away from the thread since Thursday. Takes a while to catch up. I went to Costco on Friday for the first time in weeks. I lucked out on timing (about 2 in the afternoon). We were third in line outside. When we left 50 minutes later, the line was about 40 carts deep. I like the efforts that Costco is making. I don't understand why other businesses don't, at a minimum, have their employees wear masks. I picked up two large packs of Kirkland TP and at the register and was politely told I could only get one (must have missed a sign). Not a problem, they removed one. They minimize the customers in the store. Assign you to a register and have the distances marked off. I'd say about 45% of the shoppers wore masks.

So in these studies, are they looking at just the HCWs wearing the masks? I thought the whole thing with everyone wearing masks was not to protect yourself, but to protect others? I just find it hard to believe that if everyone is wearing a mask of some sort it doesn't have an effect on transmission rates.

Yes, this study was about preventing infection in mask users in the Healthcare setting but it highlights that for SARS the masks made little difference. In my mind it can be inferred that a cloth home made mask would be less effective. Also further inferring that if a user can be infected it would be just as likely that an infected individual could also infect others. If the virus passes through the mask it doesn't matter which way it goes through. Just that it can still go through. But we know initial viral load is important so they might be a somewhat helpful in that regard.

It may help a little but I just find some of the comments here a bit much in terms of belittling people for not wearing them when it is far from conclusive that transmission rates are significantly affected by wearing a bandana on your face or any other home made mask.

Based on conversations I’ve had with my wife about her hospital’s N95 mask fitting procedure, I’d guess a lot of the failures have to do with fit. Those masks don’t seem terribly well designed for a tight fit. And since a virus is tasteless and odorless, there is no way to tell if you have a bad fit.

We use half faced respirators with P100 filters at work for our welders working with galvanized metal. The mask is designed to fit a lot tighter/with a better seal. Also, there is the added benefit that if you have a poor fit, you can taste/smell the galv and know you have a problem.
