Usage of Masks "Flattened" Growth of Coronavirus Cases in Czech Republic
https://www.praguemorning.cz/usage-of-masks-flattened-growth-of-coronavirus-
cases-in-czech-republic/
The growth of coronavirus cases has “flattened” in the Czech Republic ever
since the country’s government has made masks compulsory, claimed data
scientist Jeremy Howard.
In the Czech Republic, the growth of news is low whereas in other parts of
Europe the pandemic is largely out of control. This occurred after the
government announced it was compulsory to wear something covering a part of
your mouth and nose when leaving your residences – such as a home-made mask
or a scarf on March 18.
Howard claimed that “one of the key reasons for the decrease in the growth
of the cases is a massive country-wide community initiative to create and
wear home-made masks.”
In just 10 days, the country went from no mask usage to nearly 100 percent
usage, with nearly all the masks made at home with easily accessible
materials, like old t-shirts.
As many as nine people have died from the infection that originated in China.
Howard claimed that in South Korea, Japan, and Taiwan as theses countries
are using masks to prevent the spread of the disease. “In South Korea,
Japan, and Taiwan there is no lock-down. Yet COVID-19 is being controlled in
these countries. How has this happened?
One of the key reasons is that mask-wearing in public is ubiquitous and
socially expected,” Howard said.
As of Sunday morning, there were 2,669 cases of COVID-19 in the country,
with 13 dead. |

呼吸道传染病，无论是飞沫还是气溶胶经口鼻进入呼吸道是即时传播，而且过程不可逆
，并且这个病毒一次大量进入呼吸道黏膜，病人几乎可以保证得病，而经手接触传播你
必须要手触碰到病源，没有洗手，又触碰了口鼻，这时候病毒也只是在皮肤表面，要深
入口鼻粘附在粘膜上引起发病仍然需要时间。所以美国发明的洗手法防呼吸道传染病纯
属胡扯。这么多年用下来，flu每年美国最严重，有什么证据表明洗手是有效的？

常用物体表面可能落有多个人的飞沫，而你走在路上却很少会被多个人的飞沫击中，前
者如果发生就要洗手，后者要戴口罩
人口密度极大，周围的人又说话没有节制，应该戴口罩
川普和测出阳性的议员脸对脸说话并且握手，飞沫肯定是溅到了，但是总量不够仍然不
致病，我们都知道川普后来没有生病，因为川普解释说自己没有跟那个议员有
prolonged接触，换句话说稍加接触然后洗手，哪怕被喷飞沫，病毒总量也不够
不要觉得碰上了一定就遭，病毒总量也是因素，而不是只有浓度 |
