Question for the mask experts

Here is the conclusion to an article on masks from a dental journal that predates the politicization of mask science:
____________

The primary reason for mandating the wearing of face masks is to protect dental personnel from airborne pathogens. This review has established that face masks are incapable of providing such a level of protection. Unless the Centers for Disease Control and Prevention, national and provincial dental associations and regulatory agencies publically admit this fact, they will be guilty of perpetuating a myth which will be a disservice to the dental profession and its patients.

It was pretty easy to find, actually lol.

Article seems pretty well sourced and they don’t ‘have a dog in the fight’ so yeah.

Looking up a dental journal as any kind of appeal to authority is desperation.

I'll stop bringing up the 3 studies over the past month that have shown the effectiveness of masks against COVID spread. But I will keep talking about the now basically indisputable evidence that areas & countries that have high mask compliance do very well at keeping the #'s down, and those that don't, don't.

Even Hannity is on board now. Most Republicans that I've seen have come around. You, Trump and Teflon Don seem to be the lone holdouts.

We're just trying to slow the spread here. It's not a big ask. Everyone is doing what they can.

I don’t look down on dentists and oral surgeons.

The article sourced several studies, did you read it? And is it true CA spiked *after* their mask mandate.

Kettle fallacy.

Void argument fallacy. Redefinition fallacy. Evidence is not a proof.
that areas & countries that have high mask compliance do very well at keeping the #'s down, and those that don't, don't.
Argument from randU fallacy (use of random numbers as data).
Even Hannity is on board now.
Irrelevant.

Bigotry. You don't get to speak for most Republicans. You only get to speak for you.

Masks do not slow the spread. They do not stop a virus.
It's not a big ask.
You are not asking. You are demanding. Big difference.
Everyone is doing what they can.
No, they aren't. People like you are getting a serious case of agoraphobia. You support those that are shutting down the economy over nothing. Less than 1% of the population is infected with Covid-19, and it usually does not result in death. The pneumonia it induces can be treated with aggressive antibiotics, if caught early enough.

You are doing nothing but hiding in fear. You are demanding others to hide in fear. You are literally imprisoning yourself voluntarily. Stay home in your basement. Don't come out. Others are not wearing their masks and have no need to.
 
If one wears a mask won’t they rebreathe their own CO2?

And isn’t CO2 a greenhouse gas that causes warming?

Therefore won’t people who wear masks overheat their innards?

Our attempt to fight Covid-19 is being hampered by some of the dumbest people on Earth, like Teflon here. Is this stupidity just an act, or is Teflon really this stupid? It is hard to tell.

Masks do not hold in CO2. CO2 does trap in heat from sunlight, but skin keeps the sunlight from hitting the air in our lungs, so no overheating. I could go on and on, but it suffices to say nothing Teflon has said has any resemblance to reality.
 
Water gets trapped and nice warm water is a terrific medium to grow things.
Reuse those masks at your peril.

Celticguy got one right. I am so happy. Finally a trump supporter gets something right.

Worth noting that viruses will not grow in masks. Viruses require living cells to grow. There is a real danger from bacteria and mold in masks.
 
Anything that impedes airflow into the lungs is going to increase blood CO2 level. Masks included.

Studies show the reverse. If you impede airflow, it causes your lungs to work harder. The lungs overshoot, causing slightly lower CO2. Either way, it is not a significant amount.

Omar has got to stop giving bad medical advice.

But that can change when you start asking people to wear masks doing anything like strenuous work.

They thought that you were right, which is why they tried exercise masks. These exercise masks were supposed to increase CO2 in the blood, and cause Olympic level athletes to train in the equivalent of high altitude. It does not work.

And I cannot think of anything more strenuous than training for the Olympics. Certainly shopping for groceries do not even begin to compare.
