主题：德国人最新研究证明必须戴口罩 -- 夕曦

医用口罩就是现在国内也不是普通人在戴，疫情初期，更是口罩难求，但舆论和官方导向上开始就要求戴口罩，严格时期，不戴口罩不让进商场，出入社区。那段时期，基本都是普通防尘口罩，还有不少是自制的那种布口罩。。客观上限制了人流动，同时至少飞沫传播几率大大减少。那怕有人戴不规范，挡嘴不挡鼻，那也减少了一半传染别人的危险。。

说起来还是信不信民众的问题，信就先搞起来，那怕用围巾先裹起来也比口鼻暴露好太多了。。。这个环节一直不做，老拿文化习惯当借口，甚至歧视戴口罩的，那不活该倒霉吗？

实际上口罩不是问题，固执的观念才是。我这大多数人大多数时间里是戴很普通的防尘和自制布口罩的，口罩不缺的时间，都已经到疫情进入尾声了。这还是上海呐。。其他地区估计也差不多，不要低估民众的创造性自觉性，舆论和官方导向对头，都有办法。

但被误导了的话，那就真要付出惨重的代价了。

其实想想也该知道和常识，以中国的人口基数，疫情期间，正规口罩数量要满足这么多人的需要是不可能的。尤其在广大农村，可以确定一点是大多数人戴的口罩和医生需要的口罩需求不是一个层次，错位的。如果一定认为必须戴n95才行，那才会造成医护人员防护物资短缺。。但事实上不是，反而是因为知识的传播和疫情信息逐渐明朗化，很多人把医用口罩物资送给了最急需的医院。。前期有些官员口罩等级高被舆论批评后，再没有官员敢戴高级别的防护口罩，这就是风气对路了。。

思路对了，就会有方法，有时间差，慢慢条件就改善了。。比如上海开始通过社区登记，按家庭提供几个口罩应急。。但不戴口罩不许进商场后来不许出门。。现在了基本都不缺了。。

思路和导向第一，条件和困难第二，要相信人民的自觉性和创造性。口罩本是小事情，但对待这事的做法上，真是区别太大了。。欧美人缺自觉性和创造性吗？我觉得大多数人不缺，但很可惜，上层不信任这些，只看到困难和现有条件，上层不组织不引导，下面再有本事也是散的个体，不能形成合力。。连歧视戴口罩的都成为习惯也真是够夸张的。。谁没事想戴口罩呀？！

起码有阻挡效果，即便效果不是那么好。

欧美民众现在都要跳脚大骂了，被CDC误导至今日。。。。。

前期报道里，没戴口罩中招很普遍，还有那个郑州跑国外看球那个毒王，因为他被隔离观察了数千人，但至今自己没看到说因为他被确诊的报道。。很重要一个原因应该就是他跑回来一路上，那时候国内人员基本都要戴口罩的。。

这个自己感觉比洗手重要。仅次于不出门。

从欧美国家一个个进入抗疫状态后，竟然发现，就是武汉初期的那种混乱无序与神操作，也是能达到优良水平！！至少有人挨板子，有人担责任，也有人能做事。。再加上都是首次遇到，对病毒病情都是从一片漆黑开始，那难度系数还得加。。。

再看欧美国家的应对后，原来武汉前期操作才是正常的流程呀！！还是在地图迷雾去除的难度系数下，跟重复模式一样，连错误都一个不缺的复现。牛的是，还不是一个国家，是一个接一个国家在复现。。叹为观止！

现在口罩的保护核心是熔喷布，可以带静电，用来吸附微粒。

潜伏期就传播，会在上呼吸道繁衍，也有的不会，所以有假阴性。

看来他们根本不看中国论文，也不看中国的官方文件，新闻等等，非要自己再全部重新发现一次，厉害啊

如果你怀疑自己感染了，肯定先去医院，不会自己戴口罩还出去乱逛

过滤间隙太小，呼吸困难，所以要静电。这也是非喷溶布的口罩这次没啥用的原因，一般口罩挡细菌和花粉灰尘够用了，但挡不住病毒。

丹麦正在召集志愿者，验证口罩对抗击疫情是否有效。实验组在疫情期间，只要出门他们必须佩戴口罩。对照组完全不佩戴口罩。

4月8号开始，30天后揭晓实验结果。让我们静候结果吧...达尔文应该已经掀开 了棺材板。

China: Ok there's a new virus, from now on no one move around, if you go out you must wear a mask. Nationwide lockdown and quarantine policies implemented.

Rest of the world: Don't trust anything these fucking commies say! It's just a flu! They are trying to control everyone's life! There's no need for masks!

2 months ago

China: Start building hospitals so the medical system doesn't get overwhelmed.

Rest of the world: It's a concentration camp! They are murdering people out there! They are untrustworthy!

1 months ago

China: We are experiencing a surge of patients and this virus is super infectious via air and physical contact. We are also experiencing shortage on medical supplies and medical practitioners. Pulling everything from the country to Wuhan.

Rest of the world: Look how backward they are, not even having enough PPE for their doctors and nurses. They are clearly wrong about the method of transmission that's why they are making everyone wearing masks. They've even locked down the country and stoped the economy. What a bunch of idiots.

2 weeks ago

China: Numbers are reducing in China. People slowly getting back to work now.

Rest of the world: Fucking lier! We are seeing numbers in Italy and it clearly doesn't match data from China! Millions of people must have died! It's still spreading!

Now

China: Dude why things getting out of control out there? Where are your hospitals and why are you not in total lockdown? Were you just sitting there pointing fingers at me for 3 months, and did nothing?

Rest of the world: You fucking commies never told us how dangerous this virus is! You've been given us the false data the whole time!!!

China: I don't understand. If you never trusted me and when I say it's a big deal, it's actually a small flu, why do you think there must be millions of people died in China? If you think he number of deaths must be very high, doesn't that indicates it's a dangerous virus and you should be prepared? How could you believe millions of people have died on it, but at the same time not knowing it's dangerous?

Rest of the world: It's only a big deal in a backward country like you, where people are poor and unhygienic, where the medical system is still in 1950s, where the government covers up the figures and doesn't alarm people how dangerous it is! It shouldn't affect advanced countries like us!

China: But it is with you and killing your people now!!! Do something about it so you can still save lives!!!

Rest of the world: Not before we found everything we can blame on you!!! It's too late for us to do something now, people will just die and eventually we'll have herd immunity, but you must take the full responsibility for it!!!
