The federal government is working closely with state, local, tribal, and territorial partners, as well as public health partners, to respond to this public health threat.

Highlights of CDC’s Response CDC established a COVID-19 Incident Management System on January 7, 2020. On January 21, CDC activated its Emergency Operations Center to better provide ongoing support to the COVID-19 response. The U.S. government has taken unprecedented steps with respect to travel in response to the growing public health threat posed by this new coronavirus:
On February 2, the U.S. government suspended entry of foreign nationals who have been in China within the past 14 days.
U.S. citizens, residents, and their immediate family members who have been in Hubei province and other parts of mainland China are allowed to enter the United States, but they are subject to health monitoring and possible quarantine for up to 14 days. On February 29, the U.S. government announced it was suspending entry of foreign nationals who have been in Iran within the past 14 days. CDC has issued the following travel guidance related to COVID-19. CDC has issued clinical guidance, including:
An important part of CDC’s role during a public health emergency is to develop a test for the pathogen and equip state and local public health labs with testing capacity.
After distribution of a CDC rRT-PCR test to diagnose COVID-19 to state and local public health labs started, performance issues were identified related to a problem in the manufacturing of one of the reagents. Laboratories were not able to verify the test performance. CDC worked on two potential resolutions to this problem.
CDC developed a new protocol that uses two of the three components of the original CDC test kit to detect the virus that causes COVID-19 after establishing that the third component, which was the problem with the original test, can be excluded from testing without affecting accuracy. CDC is working with FDA to amend the existing Emergency Use Authorization (EUA) for the test, but in the meantime, FDA granted discretionary authority for the use of the original test kits.
Public health laboratories can use the original CDC test kit to test for the virus that causes COVID-19 using the new protocol. Further, newly manufactured kits have been provided to the International Reagent Resourceexternal icon for distribution to state and local public health labs. Combined with other reagents that CDC has procured, there are enough testing kits to test more than 75,000 people. In addition, CDC has two laboratories conducting testing for the virus that causes COVID-19. CDC can test approximately 350 specimens per day. Commercial labs are working to develop their own tests that hopefully will be available soon. This will allow a greater number of tests to happen close to where potential cases are. CDC has grown the COVID-19 virus in cell culture, which is necessary for further studies, including for additional genetic characterization. The cell-grown virus was sent to NIH’s for use by the broad scientific community.
Through interviews with dozens of public-health officials and a survey of local data from across the country, The Atlantic could only verify that 1,895 people have been tested for the coronavirus in the United States, about 10 percent of whom have tested positive. And while the American capacity to test for the coronavirus has ramped up significantly over the past few days, local officials can still test only several thousand people a day, not the tens or hundreds of thousands indicated by the White House’s promises.
Oregon, situated between the California and Washington hot spots, can test only about 40 people a day. Texas has 16 positive cases, according to media reports, but the health department’s website still lists only three cases. The Texas Tribune has reported that the state can test approximately 30 people a day. Other states can test even fewer. Hawaii can test fewer than 20 people a day, though it could double that number in an emergency, an official told us. Iowa has supplies to test about 500 patients a day. Arkansas, though not near a current known outbreak, is able to test only four or five patients a day.
放屁！
我不在意别人踩我。我只在意我说的是不是真的对。事实一再证明，我总是对的。
这得逻辑多狭窄或者政治感多强，才把这两者等同。
完全不是一回事好吗，批评CDC延误时机，就是前一个月所有增加测试的方式，都是好的，不管是让大学做也罢，从国外买也罢，让商业lab做也罢。中国只是很多选择里的一个而已，完全不用它也可以达到啊。现在还在讲政治，不就是中共的只讲党性的一样的思维吗。
一半漏诊率，一半误诊率的你也敢用？
没底气啦？我看你不是挺横的嘛。美国现在最大的问题，就是你这种人太多。不敢动真章，全是文字游戏。一遇到要来实的，要看点真实效果的，就歇菜了。

Re，有话好好说不行么？火都烧到家门口了，还总有人一上来就扣帽子。
中国的试剂盒很好用，不信你可以让CDC去验证一下
白宫的可信度居然跟我一个网民的可信度来对比。不知道是我的可信度太高了，还是白宫的可信度太低了。
我发现大外宣觉得自己的能力不行，目标从争取群众逐渐退化到恶心群众了。
难怪才帝说它们蠢。
给你看一看美国真实的情况Exclusive: The Strongest Evidence Yet That America Is Botching Coronavirus Testing

每个人都觉得自己代表了大部分人的意见，你不过是另一个这样的人而已。泡沫总以为自己代表了大海。这个版上不知道银刀的人有几个？这个版上知道你的人有几个？
所以才着急把试剂盒卖出来吗？
准确率太低的时候对于这个大规模传染病不见得吧。现在医生觉得这个病人疑似，想想两种场景吧：
1. 对于因为没有试剂无法测试的情况，医生只能告诉病人，你这个样子有点疑似，现在无法测试，我帮你排队去测试，你这两天在家好好隔离；病人这时候会把自己当作已经生病了，回家大多数情况下都是回家老老实实隔离。
2. 对于测试准确率低的情况，那么测完了以后，40%的病人听说自己没事，回家继续浪去了，60%的开始认真治疗。那么可能对于着60%的病人治疗会好点，但是现在也没有特效药，实际上比他老老实实在家隔离并没有特别大的变化，但是对于前面那40%可是问题大了。
你说这两种情况哪种情况对于传染病控制更好？所以一个准确率差太多的检验方式反而会带来更多问题。
另外，如果试剂准确率是30%的话，测两次是到不了60%的，只能到50%多点。
说实话，从这些话，你自己都不知道自己在说什么，完全没逻辑，抛出来这些是反驳你自己的好吧。
市场上的准确率高，更证明要早测不要等什么完美测试盒啊。
先说false negative, 告诉你了怎么解决，又来什么false positive。你可能听说个名词，他们真正的意义先搞清。没有症状false positive 就是多个没得病的在家隔离两周，这和你不测相比，留一堆在外边传染，哪个更不能接受？
至于什么贝叶斯，先搞清什么意义再说吧，不是随便抛个名词就支持自己的。
一边说本来感染的就少，一边又是几千万盒，一人两盒，就是测几千万人，和你的本来少更是矛盾。
完全没逻辑。不回了，不拉低自己智商。
你们这些人啊，死抱着错误信息，还讨论得不亦乐乎
专访新冠病毒试剂盒研发团队牵头人：如何做到3-10分钟出结果？
http://ihuawen.com/index.php?g=&m=article&a=index&id=55485
中国西南大学药学院院长胡昌华教授作为牵头人，联合西南大学、重庆新赛亚生物科技有限公司及西南大学附属公共卫生医院三方人员进行技术攻关，成功研发出一款新型冠状病毒（2019-nCoV）IgM/lgG抗体检测试剂盒。试剂盒可在3-10分钟观测新型冠状病毒病人抗体检测结果，准确率高达95%。
核算试剂盒的准确率是很高的。但是出现了假阴性。这个假阴性不是试剂盒的问题，而是这个病的特征。这个病首先从下呼吸道发病，你在上呼吸道取样，你的样品上根本就没有病毒。
胡昌华教授：出现假阴性的原因有很多。从理论上来说，专业研究分子生物学的人做RT-PCR，都有一定几率出现假阴性或者假阳性。但从技术上来讲，假阴性或者假阳性的比例都不应该是很高的。但我们现实的情况当中就有这么多患者出现了假阴性。主要是因为这个疾病本身的一些特点以及我们临床采样的一些特殊性两方面所造成的。这个疾病，患者发生病毒感染以后，主要表现并不是从上呼吸道开始，而是从下呼吸道，从肺泡这块逐渐蔓延到上呼吸道这样一个过程。那在临床采样的时候，咽拭子采集的是上呼吸道的标本，一是有可能上呼吸道还处在窗口期内，二是上呼吸道的病毒量还不够；三是采样的技术还存在一些参差。临床或者疾控的医务人员需要经过更全面、更规范的培训才能更加有效的做好标本的采集。所以说，其实核酸检测这个技术本身的准确率是很高的。
你说错了，就是有问题才导致后面更大的问题
CDC二月份自产的几十万试剂盒被“污染”，导致测试无效
所以后来才没有足够试剂盒可用
好有什么用 不够的啊
不好容易出现假阴性。
又不是买来就能都做完，你有这么多医护吗
理想很美满，假设很完美，看看现实吧，无论武汉还是美国重灾区，早行动早测，情况都会好很多。
已经不是思想实验，会怎样怎样了，而是已经发生的事实。
给CDC洗地，和给中共洗地，是同样的逻辑。耽误了就是耽误了，思想实验里的另一个世界，也不能改变现实发生的。
现在周一了，两百万个试剂盒到了吗？
美国自己不愿意买中国的试剂，还不让别的国家买，意识形态太强了。
各国购买中国病毒检测试剂，美方：伊朗无资格获中国病毒检测试剂
https://www.sohu.com/a/379037985_120082100?scm=1002.580041.1040132.PC_ARTICLE_FOCUS&_f=index_pagefocus_1&spm=smpc.content.fspic.2.1584049880721miKI8e5
在处理病毒感染的事情上，我国取得了重大的成就，而我们之所以能取得如此重大的成就，主要就是因为我们在预防管理的问题上，采取了有效措施，把病毒感染从源头上，进行了控制。而我们之所以能做好预防工作，我国研制的病毒检测试剂就功不可没。现在其他国家为了控制病毒感染，就开始大力采购我国研制的病毒检测试剂。
然而，就是在这个时候，美国方面却突然搞起了小动作。为了打压伊朗，美国白宫便公然放话称，伊朗没有资格获得中国的病毒检测试剂！企图掐断伊朗获取病毒检测试剂的渠道。据俄罗斯卫星通讯社3月7日报道，由于中国在管理病毒感染的事情上，取得了重大成就，所以许多的国家就开始效仿中国模式，并去购买中国的病毒检测试剂。
而就在各国购买中国病毒检测试剂的时候，美国白宫却对伊朗展开了限制，宣称：“伊朗没有资格获取中国的病毒检测试剂。”对于这个问题，我国科技部社会发展科技司司长，也是立即发表了讲话，声称：“病毒感控的问题，是全世界人民共同的问题，这是没有国界限制的。为了支援各国的病毒防控工作，我们已经向多国提供了用于检测病毒的检测试剂。其中，就包括了巴基斯坦、日本和伊朗等国。”
科技部社会发展科技司司长强调，我们愿意加强与世卫组织的合作，同时我们也欢迎各国科研团队，在病毒管理的问题上，与我们进行交流。很显然，对于向伊朗提供检测试剂一事，我们的态度是非常坚定的，我们并不会因为某一国的要求，就停止与伊朗的合作，在病毒管理的重大问题上，谁也不能干扰和阻止我们。返回搜狐，查看更多
采样没那么难，最起码不是瓶颈。一站式采样，不需要多少护士，一天就可以采样很多人。问题是测不了。又一个星期过去了，大部分州，依然停留在每天只能测二三十个人这种能力。如果美国真的像我主楼说的那样，一口气买它十万试剂盒来用。现在疫情就稳定下来了。但美国就是死都不肯求人。西雅图感觉都要自暴自弃了。
患病人数每过4天就翻一倍，每过两周就翻10倍。时间就是生命。上个星期的时候，10万试剂盒就可以了。现在需要50万试剂盒才能将所有潜在的病人找出来。
韩国已经证明了，放开了测量足以控制住疫情的发展。西雅图再严重，也不可能比韩国大邱更严重。你测量了，真实情况显示出来了，解决方法自然也就跟着出来了。因为不测，大家都不知道真实情况，就会无休止地争论。一半人会说问题不严重。另一半会说问题很严重。两边都在拼命吵，能量、资源，时间都消耗在内斗上了，而不是用在对付病毒上。
强大的帝国，是建立在强大的执行力上的，不是建立在漂亮的文宣上的。病毒这个事，中国政府当然犯了很多错，但是最终证明了强大的执行力。美国政府也需要证明自己的执行力。自己的人民，全世界的人民，都在看着呢。这个世界不是按照对和错来分的，而是按照强和弱来分的。你很善良，你很正义，但是你很弱，没有人会和你站在一起。国际社会就是丛林世界，大家最后会选择强者。
不看广告，看疗效。大家心里门清。谁能解决问题，谁就是牛逼。美国到底是真的狮子，还是已经是纸老虎，全世界的人都在看着呢。作为老大，始终都会面临挑战，现在最大的挑战来了。床铺说不用慌，事情很快就会过去，股市信他吗？说是没有用的，别人要看你的行动，要看结果。
马云捐给美国50万份试剂盒，如果现在能立刻用起来，50万份试剂盒足以找出所有的感染者。这绝对是雪中送碳。
还在这瞎扯淡呢
人家捐赠，帮你，特别是捐试剂盒这种可以拯救一个国家的东西。要感恩。
中国政府撒谎成行，说的话一个标点符号都不要相信，试剂盒可能是带病毒的
放心，这次一定确保厉害国饿死人，禁止对中国的粮食出口
赞。关键时刻还是private sector管用。
太棒了。测试速度上去，疫情的真实情况就会显示出来，解决的办法也会随之而来
