"There's no doubt after reading this paper that asymptomatic transmission is occurring," said Dr. Anthony Fauci, director of the National Institute for Allergy and Infectious Diseases. "This study lays the question to rest." For nearly a week, US health officials have debated whether someone can spread the virus during the incubation period, when they are infected but not yet ill. The Chinese minister of health said it could spread asymptomatically, but US authorities had their doubts because the Chinese offered no evidence.
从武汉撤回美国的那一飞机里面，到现在肯定都已经检查完了（都未必是寄到cdc中心检查）。 现在美国手里肯定也有数据了，但这是top national security。。。 看cdc今天有没有briefing，有的话这应该是重点问题。没有的话他们能喘个气，拖到周一才被质询。美国的记者脑子也不笨吧，拖到周一应该有人要问这个问题了。
Unless they displayed symptoms already (fever, shortness of breath, etc) and need to self report (in the same manner that the first patient self-report to CDC)
Fact: nobody in close contact with the Seattle patient has self reported

It is not about 人传人, it is about asymptomatic transmission, which means transmission during incubation while no symptom is present. lingling7 发表于 1/31/2020 4:24:44 PM
At least for SARS, CDC believes that symptoms would show first, so maybe that was a factor.
toffeemoka 发表于 1/31/2020 9:37:51 PM
这正是CDC自大傲慢的地方，不相信新冠病毒和以前的两个不一样。Fauci 前几天就说了 China reported isolated cases of spread before symptoms. 但他当时认为有症状传播会是大多数。 这几天过去，多了日本和德国的两个例子，还是可以说是isolated cases.
德国人报道，cdc立马就相信了

点进去看的确如此，CDC内部一直在辩论，中方从未提供任何证据，而现在德国人的paper才盖棺定论。
这也是个好消息，靴子终于落地，相信更加严厉的防护措施很快就会跟进。

数据说话，美国是靠这个，没有数据，只有天朝的假数据，你叫cdc怎么办？现在纠错了也是因为有了德国的数据
cdc到今天才宣布no doubt估计是因为昨天日本撤侨的里面两个没症状
我昨天看见那个新闻出来就知道cdc要有反应了
但是从美国现在的确诊看来，问题不大。主要是因为之前close contact的人群追踪里变成确诊的目前很少。
就拿西雅图的那个病例来说，上班接触那么多同事，从概率上来说同事里应该会有人有家庭的。但到目前位置过去这么久都没有看见确诊人数上去，这是非常好的情况。
一方面从数字上来看，疫情没有增加，另一方面联邦政府和cdc政策都跟上来了，从社会上来说新闻报道增加，各个方面表明，大家不用像前几天一样内心那么焦虑了。
date positive negative new_suspect pending total number of state with PUI
1/27 5 32 N/A 73 110 26
1/29 5 68 55 92 165 36
1/31 6 114 77 121 241 36
原来CDC没有lab要依赖别国共享信息才能决策啊，笑了
问题是别的国家也是只有天朝数据，就能提早做出更严格检测和隔离的决策。
Some viruses, including SARS, which is another coronavirus, can only be passed when a person is showing symptoms.
Others, like the flu, can be spread a day or two before the onset of symptoms.
《科学美国人》刚刚发布的科普文章
并不是相信不相信的问题，而是病毒之间有本质的差异。
SARS病毒就只能在出现症状之后，才有感染性。
而流感病毒，就可能在发病前两天隐性传播，所以穿得广。
在数据不足的情况下，把武汉肺炎的新型冠状病毒，当成SARS防范，并没有很大的问题。
当然现在证明了，这种新型冠状病毒，可以隐性传播，和流感一样容易扩散，又有较高的致死率。
这也说明了为什么武汉的感染人数会这么多（中共的瞒报数字也影响了对病毒特性的分析）。
否则要哪样？不是发源地，没有足够的病例，光凭键盘侠们瞎掰掰？
This indeed a good news.
国内早就公布了有一个病例是无症状传染啊，CDC这次不知道怎么了，一直无视国内的消息，之前还说没有证据人传人，芝加哥的一出来，它就改口了。看来它是在等实验“白鼠”的病例

没办法，谁让中国的假数据已经闻名天下了呢？谁敢相信一个谎话连篇的政府发布的信息，即便它说的很可能是真话？
全世界都被中国腐烂肮脏发着恶臭的党和政府给祸害了！！！
cdc能用活人做实验吗？中国不断变换说法逼的人家不得不亲自看到才能下定论。人家给你一点基本的benefit of doubt居然还笑人家。无耻还能更多一点吗？现在还想着攻击一下cdc拉个垫背，中国勤劳勇敢的人民何其不幸，生在这个黑白颠倒厚颜无耻为了自己的权利连脸都不要了的国度。
也要感谢日本的技术，一天就能测几百个样品。如果按照cdc的速度，一天只能测20个，根本得不到需要的数据
国内公布无症状的时候美国还不能派人去中国（1月份就表示想去但是没法去）
在这种国际政治的限制下，美国cdc（以及who）只能从中国境外的（极其有限的）病例做判断
当然境外也要是美国的友国，这种数据才有价值。
要是朝鲜伊朗有个200多好，还有人传人等等，这种数据对美国政策都是没有用滴
有很多迹象，这一次CDC真的故意拖延，故意downplay risk。不知道目的是啥。
这是急性传染病，作为防疫机构，不该宁信其有不信其无吗？为什么要给病毒打掩护呢？
从武汉撤回美国的那一飞机里面，到现在肯定都已经检查完了（都未必是寄到cdc中心检查）。
现在美国手里肯定也有数据了，但这是top national security。。。
看cdc今天有没有briefing，有的话这应该是重点问题。没有的话他们能喘个气，拖到周一才被质询。美国的记者脑子也不笨吧，拖到周一应该有人要问这个问题了。
非常不理解这一点，为什么日本确诊速度可以这么快，各国使用的确诊方法会有如此大的差异吗？
全世界，其它国家都相信这个病毒很危险，除了美国CDC。世界卫生组织公布了全球危机之后，CDC依然没有及时跟上。你帮CDC说话，除非你是CDC雇员，不然想不通你的逻辑。
你分析个啥啊。CDC一天只能测20个样品。你说的西雅图跟病例接触的那些同事，根本就不会去测他们的血样。
往好了想，为我党挡子弹；为坏了想，收集更多病例。
为什么cdc一天只能测20个样品？加拿大也是很慢，朋友医院检验的人都想不通。
Unless they displayed symptoms already (fever, shortness of breath, etc) and need to self report (in the same manner that the first patient self-report to CDC)

中国已经蔓延成这样了，难道CDC认为都是吃了野味得的？不要把美国政府机构想的多高级。
Re. 不相信中国的数据可以理解，不会取样检测啊？做个PCR能做这么慢，这还不是拖拉？
日本有足够的病人？人家是把一飞机人都测了吧。美国撤回来的那一机人有测么？
有。关键是结果要多久才能出来。。。
美国的飞机筛过体温，不过关的没回来。日本韩国的是包括发热的。
这不是 lab issue, 而是可靠的统计数据。中国过去，现在，可以预期的将来都不会提供这样的数据资料。
自己听录音吧，这是最后一个问题
https://www.cdc.gov/media/releases/2020/a0131-cdc-telebriefing-2019-novel-coronavirus.html
有测，据说全都取了样。人家也是内紧外松 😅
如果真如此，非川普莫属。他为了再任也是无所不用其极。幸好他最多只做二届。第一届他也的确做了一些好事，也该下台了。
说反了吧？CDC一向是亲民主党反川的，还不知道是不是民主党在后面搞鬼，如果真的大爆发刚好可以赖在床铺头上
真是无语。 德国病例多还是美国病例多？ 美国而且很早就有那个西雅图的病例了 ？
现在搞得CDC全靠德国的数据才能做决策一样 ？
真的是为了黑啥都不认了。
真以为各国政府跟你一样靠报纸和别的键盘侠码的字作为信息来源么 ？
你说的话有没有证据？我说的话都是以过去川普干涉专业部门的事实为根据。我是中立选民，只看议题，不看党派。美国不是一个政府发言，然后百姓起舞的国家。
要么彻底停航，要么所以人都在机场隔离14天，费用自付。只有这样了。可惜看不到CDC和政府在向这个方向努力。
cdc这次害了美国，不会有内奸在里头捣乱吧
应该是中国说啥美国cdc都不信，但是相信日本跟德国的数据，土共的credit是负数了
天朝的假数据很早前确认了人传人，
CDC要眼见为实，所以芝加哥的第二例被确诊了才开始行动
日本的技术美国去引荐一下不行吗？这么关门研究 什么时候是个头
正解
一个是柳叶刀的文章表明了有asymptomatic transmission
另外日本撤侨头一波里有两个实际asymptomatic的病人
这样印证在cdc现在对美国从武汉撤侨的那飞机人的态度，现在没症状不等于以后没症状，在一个时间点上观察pcr测试结果不能完全说明问题。
感觉他们还是以科学的态度在做事情的。
At least for SARS, CDC believes that symptoms would show first, so maybe that was a factor.
芝加哥的第二例只证明了人传人。
难道他们也想收几个病人发paper?
这正是CDC自大傲慢的地方，不相信新冠病毒和以前的两个不一样。Fauci 前几天就说了 China reported isolated cases of spread before symptoms. 但他当时认为有症状传播会是大多数。 这几天过去，多了日本和德国的两个例子，还是可以说是isolated cases.
你多关注一下新闻就知道，这次川普事事都比CDC快。
