On arrival to the United States, travelers from Wuhan may undergo health screening, including having their temperature taken and being asked to fill out a symptom questionnaire. Travelers with signs and symptoms of illness (fever, cough, or difficulty breathing) will have an additional health assessment.
What can travelers do to protect themselves and others? CDC recommends avoiding nonessential travel to Wuhan. If you must travel: Avoid contact with sick people. Avoid animals (alive or dead), animal markets, and products that come from animals (such as uncooked meat). Wash hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer if soap and water are not available. Older adults and travelers with underlying health issues may be at risk for more severe disease and should discuss travel to Wuhan with their healthcare provider. If you traveled to Wuhan in the last 14 days and feel sick with fever, cough, or difficulty breathing, you should: Seek medical care right away. Before you go to a doctor’s office or emergency room, call ahead and tell them about your recent travel and your symptoms. Avoid contact with others. Not travel while sick. Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing. Wash hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer if soap and water are not available.
CDC SARS Response Timeline SARS 3D SARS: Key Events Severe Acute Respiratory Syndrome (SARS) was first discovered in Asia in February 2003. The outbreak lasted approximately six months as the disease spread to more than two dozen countries in North America, South America, Europe, and Asia before it was stopped in July 2003. See below a timeline of CDC’s key activities conducted during the outbreak and beyond.
2002 November 16: The first case of atypical pneumonia is reported in the Guangdong province in southern China. 2003 March 12: The World Health Organization (WHO) issues a global alert for a severe form of pneumonia of unknown origin in persons from China, Vietnam, and Hong Kong. March 14: CDC activated its Emergency Operations Center (EOC). March 15: CDC issues first health alert and hosts media telebriefing about an atypical pneumonia that has been named Severe Acute Respiratory Syndrome (SARS). CDC issues interim guidelines for state and local health departments on SARS. CDC issues a “Health Alert Notice” for travelers to the United States from Hong Kong, Guangdong Province (China). March 20: CDC issues infection control precautions for aerosol-generating procedures on patients who are suspected of having SARS. March 22: CDC issues interim laboratory biosafety guidelines for handling and processing specimens associated with SARS. March 24: CDC laboratory analysis suggests a new coronavirus may be the cause of SARS. In the United States, 39 suspect cases (to date) had been identified. Of those cases, 32 of 39 had traveled to countries were SARS was reported. March 27: CDC issues interim domestic guidelines for management of exposures to SARS for healthcare and other institutional settings. March 28: The SARs outbreak is more widespread. CDC begins utilizing pandemic planning for SARS. March 29: CDC extended its travel advisory for SARS to include all of mainland China and added Singapore. CDC quarantine staff began meeting planes, cargo ships and cruise ships coming either directly or indirectly to the United States from China, Singapore and Vietnam and also begins distributing health alert cards to travelers. April 4: The number of suspected U.S. SARS cases was 115; reported from 29 states. There were no deaths among these suspect cases of SARS in the United States. April 5: CDC establishes community outreach team to address stigmatization associated with SARS. April 10: CDC issued specific guidance for students exposed to SARS. April 14: CDC publishes a sequence of the virus believed to be responsible for the global epidemic of SARS. Identifying the genetic sequence of a new virus is important to treatment and prevention efforts. The results came just 12 days after a team of scientists and technicians began working around the clock to grow cells taken from the throat culture of a SARS patient. April 22: CDC issues a health alert for travelers to Toronto, Ontario (Canada) May 6: In the United States, no new probable cases were reported in the last 24 hours, and there was no evidence of ongoing transmission beyond the initial case reports in travelers for more than 20 days. The containment in the United States has been successful. May 20: CDC lifted the travel alert on Toronto because more than 30 days (or three SARS incubation periods) had elapsed since the date of onset of symptoms for the last reported case. May 23: CDC reinstated travel alert for Toronto because on May 22, Canadian health officials reported a cluster of five new probable SARS cases. June 4: CDC removed the travel alert for Singapore and downgraded the traveler notification for Hong Kong from a travel advisory to a travel alert. July 3: CDC removed the travel alert for mainland China. July 5: WHO announced that the global SARS outbreak was contained. July 10: CDC removed the travel alert for Hong Kong and Toronto. July 15: CDC removed the travel alert for Taiwan. July 17: CDC updated the SARS case definition which reduced the number of U.S. cases by half. The change results from excluding cases in which blood specimens that were collected more than 21 days after the onset of illness test negative. December 31: Globally, WHO received reports of SARS from 29 countries and regions; 8,096 persons with probable SARS resulting in 774 deaths. In the United States, eight SARS infections were documented by laboratory testing and an additional 19 probable SARS infections were reported.
2004 January 13: CDC issues “Notice of Embargo of Civets.” A SARS-like virus had been isolated from civets (captured in areas of China where the SARS outbreak originated). CDC banned the importation of civets. The civet is a mammal with a catlike body, long legs, a long tail, and a masked face resembling a raccoon or weasel. The ban is currently still in effect. 2012 October 5: The National Select Agent Registry Program declared SARS-coronavirus a select agent. A select agent is a bacterium, virus or toxin that has the potential to pose a severe threat to public health and safety.
不avoid也进不去啊

who也是一帮官僚。
CDC recommends that travelers avoid all nonessential travel to Wuhan, China
还有更高吗？一直以为这是最高的了。
对啊，是对武汉封城的对应反应，不能过度解读
没有更高了，以后可能扩大红色预警的范围，现在只是针对武汉
马上china就会level 3的
并不是不能去就干脆别去的意思。。CDC 发布警报主要目的还是指导美国各大机场 医疗机构如何应对 我相信他们各个机构都有相应的预案。
On arrival to the United States, travelers from Wuhan may undergo health screening, including having their temperature taken and being asked to fill out a symptom questionnaire. Travelers with signs and symptoms of illness (fever, cough, or difficulty breathing) will have an additional health assessment.
你们公司反应迅速，有很多中国业务吗？
我们公司昨天就发alert了。。制药公司。。
都是什么样的傻逼，拉扯防护服，这种的就地打一针聊到。
动物才没有这么坏
荆州都这么严重了，离封省不远了。

这个我觉得应该退半票，毕竟天灾人祸不能全由一方承担。
武汉红色三级，中国其他地区绿色一级
这不明摆的吗，武汉都封城了，想去也进不去
cdc和who有什么本质分歧吗？
https://wwwnc.cdc.gov/travel/destinations/clinician/none/china?s_cid=ncezid-dgmq-travel-single-002
Watch Level 1, Practice Usual Precautions
应该说China甚至any了
3级已经是最高级别了，而且看了对healthcare provider的防护建议，基本参照国内的，尤其是那个防护镜估计就是参照可控可防王医生说的，毕竟美国没有太多的临床数据可供参考，目前临床信息基本来自中国。
2月初要出差回广州的飘过。。正愁找啥理由不去呢
re.
被红色渗透了。现在只要是不是民选的国际组织，没几个屁股干净的。
怎么做才是仔细筛查？问有没有接触史？你觉得那回答有多大的可信度呢？不可能每个都做病毒核酸检测，现在这个都只有CDC才能做，就算是各州有能力做了，也不会全面用核酸检测筛查乘客的。实验室没那个力度。
那个是国务院发，这个是cdc发的
当年台湾被害得好惨，白死而了好几十个人！
疫情就是正当理由
re
强顶着个，粉毛们全家赖在美国，骂美国，赞共产党，却死也不回国，真是恶心到家了
国务院的travel alert 是4级， CDC是3级。不是同一个东西
