Two weeks ago, Czech Republic government forced their residents to wear surgical mask. By now, the results proved it efficiently reduced the virus infectious ability.

It is sad to watch this kind of video. These westen countries keep telling people mask is useless. But by the same time, everywhere is trying to get masks. This kind of videos are not showing people real information. It helps politician to cover the truth: they do not have enough masks; they do not have ability to produce enough masks; if public use a lot of masks, medical staff will not have protection.

These mask with valves are better. Some of them have filters which can be changed when needed, and not set integrated.

what can block coronavirus sized particles by %
vacuum cleaner bag 95%
“tea towel” dish cloth 83%
Kitchen Paper , cotton shirts, pillowcases, 50%
Surgical masks 95% & 80% at 0.007 microns
under 0.3 microns The weirdness of Brownian motion starts &
allows the above to trap The 0.1 micron coronavirus

Yes, it does. If it protects the nurses and doctors who are immediately in contact with the patients, there is no reason why it doesn't protect you. Of corce you need to know how to ware it, do fit checks if needed, and know which RESPIRATORS are approved by NIOSH.The misinformation is to discorage the public from buying in mass and cause shortage of the RESPIRATORS masks to those who need them critically.

My girlfriend is posting images on her facebook today of the mask she has been sewing for Walmart staff and her fellow dialysis friends. She is a dialysis patient and has dialysis 3 times a week, and that takes a lot out of her, but she is trying to produce what she can. If your interested check her facebook page out - Jolene Morales, we are out of Prescott Valley, AZ.

Decades of studies show masks prevent healthcare workers, like me, from getting infected in healthcare settings, and prevents infected people from spreading disease to others. Now this Dr in question is calling the studies a lie. Sounds like this Dr wants people to get sick so he can make more $$$ off them.

You should take this video down because scientists are now saying that even surgical masks provide some protection; better than not having one. Even a fabric covering might provide some protection. Of course n95 is the best choice. But SOMETHING is better than nothing, along with common sense like washing your hands and social distancing.

In Asia, the doctors are telling people that they should wear masks in public. The reason why in the West they say "don't buy masks" is because there aren't enough masks to go around, and that civilians might hoard them and not use them correctly because they had never worn them before. The problem is the public's mentality and lack of understanding, not the masks themselves being ineffective.

I think wearing a mask is counter-productive because once you have worn the mask it must be
immediately disposed of ( and it just makes you look silly ). So masks are neither here nor there.

The best way to slow the spread down is to wash your hands as often as required, practise
social distancing ( we should be doing that anyway ) and of your country is in lockdown
stay at home unless you have a valid reason to leave your gates.

The virus can also make it's way through the tiny holes in the skin and it could more easily
penetrate into your system through any cuts.

This is absolutely false. There are a number of masks that are designed for reuse, either by replacing a respirator or decontaminating the filter. Hospitals are now even decontaminating and reusing N95s. Many of the masks that are effective can be simply washed with water and soap, or the filter can be replaced after a certain time. It's a fact that one of the main ways the virus is contracted is through breathing in contaminated air, and it's also a fact that masks with adequate filters (of which there are very many besides the N95) prevent a certain amount of particles in the air from passing through. In many cases, an adequate mask can filter 90-95% of harmful particles, including the virus. If you want to measurably reduce the amount of contaminated air you breathe in public, wear a mask. It's not a hard concept to understand.

China required everyone to wear a mask when out in public. A surgical mask reduces spread of sick person's germs. Covid19 virus can spread from asymptomatic people. Figure it out.. masks would help reduce contagion.

The best thing you can do is not wear a mask so doctor douchbag can make lots of $$$$ and the government has all the power. Masks empower people. Masks work because they cut off the source .

Folks the masks are a complete farce , air borne particulates are completely different it is tha mass medium particulate . If guys are not face fitted correctly they will have no effect . The filter on small particulates must be lower than 2.5pm .. Remember these people are paid to promote and pedal their wares. If your wearing a mask makes sure gentlemen you have no facial hair pre-filters and charcoal filters are offered. Good hygiene prevails every time. If you are buying a mask make sure it offers at least 99.97% filtration efficiency against airborne particulates.

New study recommends wearing the mask including the surgical mask. If you have it incubating it the surgical mask will prevent it from spreading it and it’s still better than nothing.

Let's do the math. 10% risk means 90% protection. 10 times less spread of infection.. deaths. But it gets even better when both patiënt and doctor wear a mask. 10%x10%=1% risk. 99% protection. If a doctor wears KN95 = 95% all day and a surgical mask for each different patient. The math is 5%x10%x10%=0,05% = 99,95% safe. So do not question the use of masks! They make a difference!

and it spread the disease everywhere, and the irony is that they put mask on

Wealthy Prosperous Nurses and other healthcare workers come into contact with many more people and need to protect **the patients**. Also, a nurse or doctor getting sick is much worse than anyone in the general public getting sick. Bottom line: non-medical people are less valuable in this situation than medical people.

Hi
Hi - 4 天 前
wearing masks or not is definitely a cultural thing, in north-east Asia like Taiwan, japan, china, Korea, it's so normal to wear a mask in our daily life even when there was no virus, everything and anything can be the reason to wear a mask:
the air pollution is so Serious recently so I have to wear a mask,
my nose is allergic recently so I have to wear a mask,
I just had plastic surgery and I'm still recovering so I have to wear a mask,
I'm so ugly so I have to wear a mask to cover my face...ext

If 50% does not use masks the correct way, the answer is not to tell all to not use masks, but to tell people how to use them correctly.
Masks work, and there is not a huge difference from N95 to surgical masks.
Even a scarf or other covering will give a little protection.
