What a dramatic 180 degree turn. The official narrative has changed from masks don’t help, to masks are the most urgent priority in the nation.

Do you have extra masks? Donate them! Industries must manufacture masks ASAP! Everyone get out their sewing machines and make masks!

It’s a 1984 cliche, yet hardly anyone notices. Move along, nothing to see here. We have always been at war with Eastasia. And don’t forget to wear your masks comrades.

Had to see a physician the other day and they were wearing masks. I asked about that and they said, "It works agains the Flu." I mentioned that it could get through to them from around their eyes and they looked at me like I was crazy.

Yeah, to be truly safe you need your eyes “sealed” too. It’s all a matter of how much safer. They say that normal glasses help stop spread to a certain degree. Sealed googles are even better. A lot of them use a large clear shield, but there are air gaps with that too.

They said that regular surgical masks (not N95) didn’t stop small enough particles, yet now they are saying that they do help protect, and especially in containing coughs if a person is contagious. An official yesterday was recommending that everyone wear some type of mask, even if it isn’t perfect.

Complete opposite of what was said at the beginning.

They way I heard it put is the mask is most for people to not spread their own germs rather than protection.

If that is the case, everyone should have been directed to wear masks like you see in the pictures of Korea or Japan because you don't know who is infected. That does create a massive demand, but that would have been avoided by increased production months ago.

They were probably lying so as to keep people from buying them all up and the medical folks having a shortage.

And for that purpose, a homemade mask would work too. They have been showing on the local news some of the homemade options, usually made out of cloth.

It depends on the type of the ask. The surgical masks that most people are wearing protect others from you infecting them, but they don't protect you. You need a n95 mask, the kind you get at the hardware store.

Helpful.

So if everyone wore a surgical mask, transmission would be nearly zero.

And I wouldn’t say that surgical masks are not helpful. A mask that might block some percentage of floating droplets is better than nothing at all. They just aren’t as effective as n95 masks.

Same as eyeglasses being better than nothing for protecting the eyes.

A mask doesn't seal and protects others from your drops coming out.

A respirator seals and protect you from other's drops.

The N95 is a respirator, not a mask.

Here is a link to Mayo clinic info: https://newsnetwork.mayoclinic.org/discussion/covid-19-when-should-you-wear-a-face-mask/

COVID-19 can cause a number of symptoms that may appear several days after exposure. The most common symptoms are cough, fever and shortness of breath. The virus is primarily spread by respiratory droplets transmitted via close contact (within 6 feet) with an infected person, according to the Centers for Disease Control and Prevention. Respiratory droplets are produced when an infected person coughs or sneezes.

The increase in the general public buying surgical face masks has resulted in mask shortages for some health care workers. So should you wear a face mask to protect yourself from the virus, even if you're not sick?

"The current recommendations regarding masks are that if you yourself are sick with fever and cough, you can wear a surgical mask to prevent transmission to other people. If you are healthy, there is not thought to be any additional benefit to wearing a mask yourself because the mask is not airtight and does not necessarily prevent breathing in of these viral particles, which are very tiny," says Dr. Nipunie Rajapakse, a Mayo Clinic infectious diseases specialist.

If you are going to a clinic or hospital to be seen by a health care provider because of concerns of cough or fever, Dr. Rajapakse recommends wearing a face mask to avoid transmitting possible infection or virus to other patients and medical staff. Face masks also are recommended for health care workers and people who are taking care of someone infected with COVID-19 in close settings (at home or in a health care facility).

"Most people who do not work in a health care setting have not received training on how to put on and take off the masks properly. Doing this incorrectly can actually increase your risk of infection. Also, people who are wearing masks tend to touch their face more than those who are not, which can paradoxically result in an increased risk of infection as well," says Dr. Rajapakse.

She says instead of wearing masks, people need to:

Wash their hands frequently using soap and water for 20 seconds or an alcohol-based hand rub.
Avoid touching their eyes, nose and mouth.
Practice cough etiquette. Cough into a flexed elbow or tissue, discard the tissue in the trash, and wash hands.
Stay home from school, work and public places if feeling unwell.
Check the CDC website for additional updates on COVID-19.

Technically, yes. The common people call them all masks.

I used to prefer a respirator with dual changeable filters when I worked in a chemical lab. I called the dust filters that some people wore “marble masks”. They are guaranteed to prevent you from inhaling any marbles floating in the air. ;)

Let’s dissect this Mayo Clinic statement...


Here is a link to Mayo clinic info: https://newsnetwork.mayoclinic.org/discussion/covid-19-when-should-you-wear-a-face-mask/

COVID-19 can cause a number of symptoms that may appear several days after exposure. The most common symptoms are cough, fever and shortness of breath. The virus is primarily spread by respiratory droplets transmitted via close contact (within 6 feet) with an infected person, according to the Centers for Disease Control and Prevention. Respiratory droplets are produced when an infected person coughs or sneezes.


Ok, repository droplets. I remember when they were telling us the only way to transmit was by touching your face, and hand washing was the only preventive measure.


"The current recommendations regarding masks are that if you yourself are sick with fever and cough, you can wear a surgical mask to prevent transmission to other people. If you are healthy, there is not thought to be any additional benefit to wearing a mask yourself because the mask is not airtight and does not necessarily prevent breathing in of these viral particles, which are very tiny," says Dr. Nipunie Rajapakse, a Mayo Clinic infectious diseases specialist.

There is the slight of hand. At first it was respiratory droplets, now they are talking about viral particles. Two different things. They are comparing bowling balls to marbles. Droplets are much larger than the virus itself. And droplets are what is in the air, right?

Not airtight and does not necessarily prevent transmission? More weaseling. It is some protection. Not perfect, but better than nothing. Do all curtains block out all light? No. But even thin curtains cut out some of the light.


Also, people who are wearing masks tend to touch their face more than those who are not, which can paradoxically result in an increased risk of infection as well," says Dr. Rajapakse.

Here’s another paradox. Every time there is an additional business shutdown or shelter in place announced, half the population crowds together at the grocery store. By this logic, all shutdowns and shelter in places should never have taken place.


She says instead of wearing masks, people need to:

Wash their hands frequently using soap and water for 20 seconds or an alcohol-based hand rub.


Wash our hands. Repeat ad nauseum. We get it. It’s a good thing to do. It doesn’t stop airborne disease though. And we’ll all run out to the stores everyday and crowd together in a futile search for hand sanitizer. Another one of those paradoxes.

Point taken. But when you have people buying up surgical masks that don't need them then there are less masks available for....surgery. So in the aggregate it's not that helpful. You get about as much mileage from a bandanna as you do from a surgical mask for stopping viruses. The CDC should have said wear bandannas. Give people something positive they can do. I guess this would be like wearing a sheepskin condom in the early days of the AIDS epidemic. Sure, I suppose it wouldn't hurt and might slow the virus down some by blocking some of them, but it could also give a false sense of security.

That said....I have N95 masks for sale. (Seriously).

Thanks for the detailed response, there is definitely some wiggling by the experts because of a lack of data on the virus and supply shortage at the moment. After reading it I took away that if you are sick wear a surgical mask if you are headed into a "hot zone" (supermarket, hospital) wear some type of mask. Finally, wash your hands, shower and change clothes immediately.

I just thought it would be helpful to insert some simle facts. :)
