The most simple face mask (not a gas mask) does not protect you from environment, it protects other people from you. Hoarding prevention is also a very important task in the midst of a crisis. Hence WHO recommendation is justified. Moreso a mask can be a cause for reinfection with virus, since you are breathing back in what you exhale. Best wishes and good health.

I fail to understand this.

>The most simple face mask (not a gas mask) does not protect you from environment, it protects other people from you.

>Moreso a mask can be a cause for reinfection with virus, since you are breathing back in what you exhale.

>Hoarding prevention is also a very important task in the midst of a crisis. Hence WHO recommendation is justified.

These three sentences can be boiled down to:

- WHO's recommendation is justified to prevent the hoarding of that item because:

If you're sick, wearing it will harm you and protect others. If you're not, it's useless to you.

Therefore, only sick people wanting to remain sick should wear them. That excludes physicians who may not be sick, and do not wish to remain sick if they already are.

Furthermore, is the protective property on the simple face masks anisotropic? How does it protect in a way and not in the other? Does a mask of non null thickness and non null fabric count protect less than no material? Will it prevent absolutely no harmful particle from getting to me?

  Sick++||     Healthy   (works when sick wears it)
  Sick+     +||Healthy   (fails when healty wears it)

Do I understand this correctly?

When a sick person exhales into a mask, majority of fluids stop at mask. Why? Because fluid dynamics and inertia.

When a healthy person inhales wearing a mask big part of the air comes from the side, because it's an easier route and because fluid dynamics. Then healthy person touches their eyes with unwashed hands and still gets infected.

Official recommendation for sick people as far as I am aware is to change the mask every couple of hours, because by then enough fluid accumulates on the mask to pose threat.

"it's useless to you" - it's a freaking pandemic - nothing is about you, the fight is to stop exponential growth of the infected.

Yes, and I'm doing my part by establishing work from home for the company, and staying home for weeks. What I'm asking is that the leading authorities not indulge in fuckery by spreading misleading information on how masks are useless for sane people on one hand, and on the other hand urge people to leave these masks to medical professionals.

I'm doing my part to stop the exponential growth, they need to do theirs. One good start is not to spread lies.

Now that is helpful!

What exactly you see as lies?

[Jugurtha]

>What exactly you see as lies?

The World Health Organization saying that wearing masks does not work, and misguiding people on a planetary scale.

A mask is a limited resource.

A mask is better spent on a sick person.

Therefore a healthy person should concede a mask to a sick.

Or maybe this is gonna be more illustrative: Let's say you are a magicall 100% efficient authority. You have 1000 people on your hands and only 500 masks. What is the course of action that yields least amount of deaths? Yep, you lock away all the masks and give them away to sick people.

It is wartime logic - deaths are inevitable and if you shoot in the head people hoarding masks you will DECREASE total deaths.
