Kirk Cousins Is An Incredible Moron
I wonder if he'll let nature take its course if he has an injury or will he let medical science treat and repair the injury? What a twat.

"these masks really are not much different than no mask at all when talking about normal breathing."
which masks are you talking about? you mention each type of masks provide differing levels of protection but seem to lump them all together as you comment.

Maybe this source is a little better... NYPost with Duke research:
https://nypost.com/2020/08/09/scientists-tested-14-types-of-masks-in-preventing-spread-of-covid-19/
N95 masks, often used by health care professionals, worked best to stop the transmission of respiratory droplets during regular speech.
Other good performers at stopping leakage were three-layer surgical masks and cotton masks, which can be made at home, the researchers with Duke’s physics department found.
But while bandannas and knitted face coverings may be a unique look, they did not offer much protection, according to the study.
The scientists also discovered that neck fleeces, or neck gaiters, often worn by runners, were the least effective and actually allowed more respiratory droplets to escape than not wearing a mask at all.
That’s because they were shown to break down larger droplets into smaller particles, allowing them to slip out the sides of the covering more easily.
Yes on the first post... it kind of hit home for me because I have a nurse for a wife. She has explained to me to the point of exhaustion that N95's are the only mask that 'really' works. The rest just stop larger droplets.
Thanks for the welcome to the board :).

"Other good performers at stopping leakage were three-layer surgical masks and cotton masks, which can be made at home, the researchers with Duke’s physics department found."
it says cotton masks, which i assume are cloth masks, to work well as well.

Non N95 masks provide various levels of protection against larger droplets but virtually no protection against aerosols (virus sized particles).
Non N95 masks is what I am referring to for the masks we all are wearing.
September 2nd, 2020 at 6:31 PM ^
the study in the article you posted supports that non-N95 masks such as surgical and homemade cotton masks work as well.
September 2nd, 2020 at 7:05 PM ^
Against large droplets... Yes. To varying degrees based on what they are made out of. They do not protect against aerosols. Only N95's do that.

"The authors found that N95 respirators filtered out 97% of a test aerosol while surgical masks did almost as well, filtering out 95% of the aerosol."
https://www.centerforhealthsecurity.org/cbn/2007/cbnreport_02152007.html
"we have measured the filtration efficiencies of various commonly available fabrics for use as cloth masks in filtering particles in the significant (for aerosol-based virus transmission) size range of ∼10 nm to ∼6 μm and have presented filtration efficiency data as a function of aerosol particle size. We find that cotton, natural silk, and chiffon can provide good protection, typically above 50% in the entire 10 nm to 6.0 μm range, provided they have a tight weave... ...In summary, we find that the use of cloth masks can potentially provide significant protection against the transmission of particles in the aerosol size range."
https://pubs.acs.org/doi/10.1021/acsnano.0c03252
N95 masks themselves do not provide 100% protection. The 95 in N95 means that it filters at least 95% of airborne particles. non N95 masks such as surgical masks and cloth masks can also filter aerosols to varying degrees.
I would say majority of medical opinions consistently say masks work.

Go back and take a look at the studies I posted and your study. The main difference between them are the particle sizes they are testing against. Your study is testing against much larger particle sizes and therefore is saying cloth masks provide protection. i.e. protection against coughing and sneezing sized droplets, not virus sized aerosols.
I know N95's are rated at 95% efficiencies against small aerosols if they are properly fitted, on a clean shaven face, and only worn once. I basically have stated that in every post.
My point all along is that non N95 masks are not very effective against small aerosol sized particles especially when you take into account they are often not worn properly, not sealed to face, and worn multiple times. They will help against large particles (coughing) but provide very little protection against particles in the air thru normal breathing.
Masks are an easy and efficient way to ensure people are coughing sneezing into their elbows. Do not get comfortable for one second thinking you are safe by wearing one indoors in poorly ventilated rooms. That is not what non N95 masks were meant to protect against.
So yes - wear masks but also understand where you are protected and where you aren't.

The study i posted says they looked at aerosol sized (0.01um) particles.
That is smaller than the 0.02 um one of your posted study used.
No one ever said they, including N94 masks, make anybody completely safe from the virus.
The overall medical opinion always was they greatly reduced the risk to spread the virus. There is no differing of opinions regarding the masks in the medical field.

Directly from your article link:
Surgical masks have long been the recommended respiratory protection for diseases transmitted by large droplets (>5µ) such as plague or meningococcal meningitis. For diseases such as TB that are transmitted by small droplet aerosols, an N95 (or better) respirator or powered air purifying respirators (PAPRs) with high efficiency particulate absorbing (HEPA) filter is recommended. It has been generally assumed that a surgical mask provided little protection from aerosols. With SARS and influenza, both droplet and aerosol transmission may occur, although the relative importance of each is debated.

Yeah, the AAPS doesn't count as "medical opinion"
September 2nd, 2020 at 2:22 PM ^
And "science" one time thought the earth was flat. Things change, especially the "expert" opinions on COVID which change weekly, sometimes daily - but we're supposed to go with it.
September 2nd, 2020 at 2:46 PM ^
you should be banned
September 2nd, 2020 at 3:25 PM ^
I believe the term you’re looking for is “canceled.” Stop being a fool. I will fight for someone’s right to free speech, even if I don’t agree with it... that is until they try to oppress others’ right to free speech. Then they can kiss my butt.

Boliver should have been banned for his meltdown this weekend, but he's a long time poster so I assume the mods gave him a break or didn't notice him telling people they are fucking sheep.
September 2nd, 2020 at 3:27 PM ^
They change BECAUSE THEY LEARNED MORE. Jesus.
September 2nd, 2020 at 5:21 PM ^
when did science ever think the earth was flat?
September 2nd, 2020 at 5:30 PM ^
It never did. The classical Greeks knew it was round. One of the Latin words for world is Orbis, which literally also means round. Think Orb.
We knew the earth was round 2,500 years before Columbus failed at basic math.

Man, this shit is making me start to consider possible similarities between medieval times through the enlightenment period, but sort of in reverse. I don't like this feeling.
September 2nd, 2020 at 2:36 PM ^
I'm usually the last one to defend Kirk Cousins, but where did he give any medical advice?
September 2nd, 2020 at 5:27 PM ^
What are you talking about? He didnt give medical advice. He was asked a question and said he doesn't fear for himself. If he gets it he gets it. If he dies he dies, but out of respect for others thinking and health, he wears one. You can think he has a dumb train of thought but he is still respecting everyone else
September 2nd, 2020 at 4:49 PM ^
Let's not be logical when people are being fascist. That's disrespectful.
