on the antibodies generated. A new article in recent Science stated that their vaccine is effective against many strains of covid-19 in monkey; of course it needs to be tested in human. It is another vaccine in China.
if i remember it right, the first report suspecting it is
airbone is from China.
My personal opinion: passing through droplets is the most provalent way; airbone is much less efficient. So face masks are very efficient. Even if it is airbone, face masks cannot stop 100%, but will still greatly reduce the chance than nothing.
这个比气溶胶droplet还厉害吧，就是空气传染？
may solve 99.5% of the problems. See Japan, Taiwan, Singapore.
保证，带口罩绝对有用。病毒就是极小的nano particles，一般的口罩也是很好的physical barrier，能挡住不少。自然空洞越小的口罩，效果就越好。我就不明白，这个有什么好讨论的。
所以能通风的地区问题都不大。
能挡住全部的。不明白美国为啥为这莫简单的问题争论。
如果憋的难受，就不要出门。自由总是要牺牲一点。
by the way，我前两天下班回家开车，车内温度都112 了。
这病毒就是给人类自然减员的。
我这里mandate了，所以都要带。在车里摘了
再碰上几个熊孩子恶作剧
人类社会太复杂没有理想状态。
邮轮那么封闭的空间传染率都只有20%
在以前遇到过这种病毒，H1N1。H1N1是当年西班牙流感病毒；传了3，40年，后来又来了另外的病毒（好像是“香港流感”，H3N2), H1N1才不怎么出现了。然后就是09年再跳出来，如今一直有。
The amount of virus necessary to make a person sick is called the infectious dose
For covid-19, the infectious dose is not known yet, but it is believed to be in the region of a few hundred or thousand viruses.
的人我们根本不知道。
不仅WHO，各个国际组织都在排队找自己的靠山
