编辑：我们从捷克共和国卫生部长那里向其他卫生部长和政府添加了一条新的紧急消息：https://www.youtube.com/watch?v=jZtEX2-n2Hc请分享，帮助我们：拯救世界各地的生命。

使用自制面膜的关键论点：
自制口罩在个人防护方面部分有效，但对于减缓病毒在人群中的传播至关重要。我们研究的主要结果是，它们可以阻止人们通过呼吸，打喷嚏和咳嗽散发的95-100％的病毒。人是没有症状的最具感染力的第一天，这就是为什么我们需要所有人戴口罩的原因。

我们已经在两所主要的技术大学成功地检验了这一假设，在捷克技术大学布拉格校长的协调下，专家小组COVID CZECH强烈推荐该假设。该团队由病毒学家，流行病学家，专门从事人口保护的医生，化学家和物理学家（如果经过过滤）组成。该小组是布拉格捷克政府的咨询专家小组。现在在全国必须戴口罩。

请分享并帮助传播可以挽救生命并减缓流感大流行的关键信息。

  1. EDIT: Big news! WHO is changing its position about face masks. Now, our video and recommendation are both in alignment with the official WHO opinion: https://bit.ly/WHO_masks

    EDIT: We have added a new and urgent message from the Minister of Health of the Czech Republic for other health ministers and governments: https://www.youtube.com/watch?v=jZtEX2-n2Hc Please, share and help us to save lives around the world.

  3. Hi guys, I'm from Italy and I'd really like to share your words with my contacts in centre and south Italy, in those regions where we still have a chance to block the spread of contagion; problem is that a video in english is really scary for italians, especially the elders, even with subtitles. Are you planning to release dubbed versions?

  4. Really, no. Don't exist exact scientific evidence about efficiency of chrirurgical masks against viruses with diameter about 120 um. Chrirurgical mask stop cca 2 – 5% particles with diameter about 120 um during cca 2-3 hours during which is mask carry.

    In pandemic of Russian influensa (1899-1905) and Spanish influensa (1918-1920) peoples also wear face masks. Don't exist differrence between sick and dead in cities with required masks on public places and and cities which don't required face masks. Only self-isolation, public hygiene & desinfection and distance between peoples 6' and more help minimalize new sick and dead persons.

    Czech Republic have relative small number of seriously sick & dead patients, because 1. almost everyone peoples was vaccinated against tuberculosis (pnæumoniæ) and we don't why, but peoples with this immunomodulation have less respiration diseases, and we don't why, but this peoples have not so strong damage of lung from Covid, 2. Czech Republic have very strictly restrictions of public life – all churches are closed (nobody in history we close churches!), all school are closed (in Protektorat, during WWII, we had last close school), state border is closed, all shops and stories are closed, excluded pharmacy, food stores, haberdasheries, and a few other exceptions and 3. we are nation of rats and polecats, peoples are voluntarily at home, excluded situations in which they really must go out, because they are worried about life (included counties with 2 Covid positive persons and towns without any positive person!?‍♂️)

    "Miracle veil" against Covid don't exist, FFP3 respirators have maximum efficiency about 90%, modern military gas mask is protect device with efficiency more than 99.99%.

  5. The WHO, the CDC and the u.s. government administration all untruthfully told us that face masks were unnecessary so that more face masks would be available to medical providers. But the fact is, there would be less patients for medical providers to see if people were told to wear them and it was required. It's irresponsible to lie to people and irresponsible to not supply medical staff with the very basics to stay safe. They not only did not require masks, and still do not, they discouraged it. Shame on them for their dishonesty and shame on every one that is directly responsible for the lack of masks, gloves, ventilators and other supplies. We could have had more supplies. We could have had less cases also. The degree to how out of hand this got was preventable. This is not our first pandemic, there were signs that were ignored by those we listen to for guidance. Thank you Czech Republic for being so smart and caring by protecting your citizens.

  6. Siempre lo dije , llevar mascarilla es fundamental, puesto que con solo hablar estas diseminado el virus y aunque parezca increíble este virus viaja a 5 metros con las gotas de flugge en los cuerpos de gohn, la distancia de 1.5 metros es inútil e ineficaz , si no tienes mascarilla. Los expertos salieron a desmentir en un momento este hecho diciendo que el uso de mascarilla era sólo para los infectados, una mala información que nos ha costado muchas vidas , pues como sabes tu quien esta infectado ?¡ pues el protocolo de actuación fue violado por cientos de turistas no cumpliendo la cuarentena obligatoria, hecho que también nos ha costado muchas vidas .Nosotros sabemos de protocolos y estadísticas pues el virus no lo sabe .

  11. It amazing that WHO still does not get the importance of people wearing cotton made face masks i,e, none medical. As per their comment saying it is not bad idea. They can not see the light that if people start wearing these masks they would not be contaminating surfaces. mean while keep washing hands and the social distancing have the virus being given a chance to live granted that it will slow its progress.

  13. May I ask who produced this video? Where did the funding come from? We've never use face mask during all previous flu pandemics, so why use them this time?

  15. 3M N95 face masks cost about 4 USD each, surgical masks cost about 15 cents each and come in boxes of 30, 50, or 100. You can buy them on Amazon. Daily uses of surgical mask for flu or air pollution is just common sense in China, Japan, and Korea. In Japan especially people wear surgical masks so that they don't sneeze or cough in public. It is for the protection of others! WHO have no brains. People died because of this mistake.

  19. there is lack of facemasks in Poland , so people are not wearing it . And we can't import them even from you . And goverment are liars . They put 440 mln Euro into tv propaganda ,they do nothing to help people who can't go to work .

  22. W Hiszpanii w filmiku ratownik pokazał, jak większość maseczek zapobiega rozprzestrzenianiu się aerozolu z wirusem – w ogóle nie zapobiega, tylko chirurgiczne i te z filtrami zapobiegały rozprzestrzenianiu się aerozolu podczas kichania.

  23. Czechs are famous for their precision machines and firearms. Yes you Czechs are smart, sensible and practical people.

  24. Be obedient sheep. Believe in everything media has told you. The corona plague is out there to get you! Now panic. Only the government can save you.

  27. Population of…
    …Czech Republic: 11 million // People Infected per 100k: 43.2
    …Poland: 37.8 million // People Infected per 100k: 10.2
    …Austria: 9 million // People Infected per 100k: 136.2
    …Germany: 84 million // People Infected per 100k: 110.6
    …Slovakia: 5.5 million // People Infected per 100k: 8.9

    Hmmm. Seems to me you need some better research and CURRENT STUDIES/INFO. All the stuff you listed was for other diseases from 7 to almost 20 years ago.
    ..
    Masks are a good idea…but I seriously doubt they will 'fix' the problem. The problem isn't someone coughing in front of you, or directly onto something. The problem is people going out. When at home, you're not wearing your mask. If you are infected, you can have the virus on your hands, your shirt, your shoes, you coat, your gloves…and your mask. You reach into your pocket to get money to pay for something….now the virus is on the money. And the guy who just took it. And the guy who he's going to hand it to to make change. And probably the counter top. And the door handle to the store. And all the products you touched. And…and…and…
    …
    So, masks MIGHT help in the single instance of you walking down the street, passing someone who has it at the exact time they cough in your general direction, within 6' of you. Then your mask might help (and their's). But that is a pretty specific circumstance.
    ..
    You'd probably be better off carrying around three rolls of that toilet paper you hoarded and using that as a 'glove' to touch anything you have to and immediately throwing that bit away.
    ..
    Sorry to be a Debbie-downer…but lets be realistic. Masks might help…but they sure as heck aren't NEARLY as effective as just staying inside as long as possible; days or even weeks. (I do…but then again…that's my normal lifestyle, so C-19 hasn't changed my daily living much at all, tbh)

  29. Le port de masques faciaux réduira le taux d'infection du COVID-19. lorsque vous êtes à l'extérieur de votre maison, portez un masque. Pour autant que je sache, les masques N95 sont meilleurs que les masques chirurgicaux, mais tout ce qui empêche de respirer les particules d'humidité avec des virus aide. Encouragez vos voisins, l'immeuble à appartements et le gouvernement de la ville à porter des masques. Si vous ne portez pas de masques, vous serez considéré que vous n'appréciez pas votre vie. J'ai donc acheté des masques en ligne sur ojomask.com et il a fallu près de 9 jours pour les recevoir. Je pense que le temps d'expédition deviendra plus long à l'avenir. Et la recherche montre que les masques faits maison peuvent être très efficaces pour se protéger contre les virus. J'apprends à faire des masques maintenant.

  30. You have twice as many coronavirus cases as Thailand and three times more dead people of coronavirus than Thailand and you have ONE SEVENTH as many people as Thailand – and your Czech Republic is a success? Because you dress like a cowboy? Are you sure?

  35. O co tu chodzi? Przecież w Czechach zmagają się na podobnym poziomie statystycznym z wirusem co w wielu innych krajach. To czemu nagle wstawiony jest filmik, który sugeruje wyjątkowo skuteczne przeciwstawianie się zarazie? Nawet biorąc pod uwagę, że filmik jest wstawiony od gdzieś ponad tygodnia.

  40. So unlike the American influencers, the Czechs influencers made the right choice and promoted the idea of wearing a mask. Very good for them!

  47. A​ very​ sincere​ plea from​ the​ Czech people, support​ed​ by​ scientists.​ Here, in​ Bangkok, too, people​ wear​ masks​. If​ not, they​ wont​ be​ allowed​ into​ public​ building​s, including​ banks.​ (Their​ temperatures are​ taken​ before​ they​ access​ the​ building, too.)​ Here, the​ Royal​ family, Prime Minister, MDs​ and​ news​ reporters–everyone, whether​ they​ are/look​ healthy​ or​ not​–wear​ masks​–even​ when​ they​ are​ on​ TV.​ And, similar to​ the​ Czech​ people, some​ group​s​ have​ started​ to​ make​ them​ at​ home​ to​ donate​ to​ the​ needy.​ (But, of​ course, there​ are​ some​ crooks who​ hoard them​ or​ sell them​ online​ at​ exorbitant prices, and​ are​ arrested)​ In​ any​ case, this​ big​ crisis​ show​ us​ people​'s​ true​ nature and​ the​ blessed​ souls​ are​ revealed​.​
    In​ every​ crisis, there​ is​ an​ opportunity!
    Let's​ encourage each​ other​ to​ wear​ masks​ to​ protect​ ourselves and​ others​ from​ the​ virus.
    Many​ thanks​ to​ the​ Czech​ folks​ for​ making​ this​ wonderful​ video.​
