美国疾控中心证实美国第1例新型冠状病毒感染的肺炎病例 入关排查机场增加至5个
2020-01-22 05:16
当地时间1月21日,美国疾病预防与控制中心(CDC)公布了美国境内第一例新型冠状病毒感染的肺炎病例。

美国境内首个病例发生在西海岸华盛顿州的西雅图市斯诺霍米什县(Snohomish County)。病人此前曾赴武汉周边地区旅行,他返回美国时没有任何症状,但在网上看到了有关病毒的消息,当他开始出现症状时,他立即联系了他的医疗保健提供者并入院治疗。根据患者的旅行史和症状,医护人员怀疑可能是新型冠状病毒感染的肺炎,就收集了一个临床标本送往CDC,通过病理分析,CDC于当地时间本周一下午确认该男子感染了新型冠状病毒的肺炎。该男子称,他没有接触过冠状病毒感染患者,也没有去武汉的海鲜和家禽市场。

美国媒体报道称,病人三十多岁,目前病情稳定。当地政府拒绝透露病人的身份,据说病人病得很重。

美国疾病控制与预防中心(CDC)17日宣布,当日起美国的三个机场(旧金山国际机场、纽约肯尼迪国际机场和洛杉矶国际机场)将对从中国武汉直飞或转机前往美国的旅客进行入境检查,以检测旅客是否存在发烧等新型冠状病毒感染的肺炎相关症状。美国媒体报道称,确诊的这名首个病人在17号前入境美国。

CDC本周还将在亚特兰大(ATL)和芝加哥(ORD)的两个机场增加入境健康检查。

另外,CDC已将其针对中国武汉的旅行安全警示通知从1级提高到2级;如果情况严重,可能提高到3级。截至当地时间周二下午,CDC建议旅客“加强警惕”,并将状态提高为“警告-2级”。最高级别的“警告-3级”是建议旅行者“避免不必要的旅行”。(总台记者 张颖哲 刘坤)




First Travel-related Case of 2019 Novel Coronavirus Detected in United States




Press ReleaseFor Immediate Release: Tuesday, January 21, 2020
Contact: Media Relations
(404) 639-3286The Centers for Disease Control and Prevention (CDC) today confirmed the first case of 2019 Novel Coronavirus (2019-nCoV) in the United States in the state of Washington. The patient recently returned from Wuhan, China, where an outbreak of pneumonia caused by this novel coronavirus has been ongoing since December 2019. While originally thought to be spreading from animal-to-person, there are growing indications that limited person-to-person spread is happening. It’s unclear how easily this virus is spreading between people.The patient from Washington with confirmed 2019-nCoV infection returned to the United States from Wuhan on January 15, 2020. The patient sought care at a medical facility in the state of Washington, where the patient was treated for the illness. Based on the patient’s travel history and symptoms, healthcare professionals suspected this new coronavirus. A clinical specimen was collected and sent to CDC overnight, where laboratory testing yesterday confirmed the diagnosis via CDC’s Real time Reverse Transcription-Polymerase Chain Reaction (rRT-PCR) test.CDC has been proactively preparing for the introduction of 2019-nCoV in the United States for weeks, including:
  • First alerting clinicians on January 8, 2020, to be on the look-out for patients with respiratory symptoms and a history of travel to Wuhan, China.
  • Developing guidance for clinicians for testing and management of 2019-nCoV, as well as guidance for home care of patients with 2019-nCoV.
  • Developing a diagnostic test to detect this virus in clinical specimens, accelerating the time it takes to detect infection. Currently, testing for this virus must take place at CDC, but in the coming days and weeks, CDC will share these tests with domestic and international partners
  • On January 17, 2020, CDC began implementing public health entry screening at San Francisco (SFO), New York (JFK), and Los Angeles (LAX) airports. This week CDC will add entry health screening at two more airports – Atlanta (ATL) and Chicago (ORD).
  • CDC has activated its Emergency Operations Center to better provide ongoing support to the 2019-nCoV response.
CDC is working closely with the state of Washington and local partners. A CDC team has been deployed to support the ongoing investigation in the state of Washington, including potentially tracing close contacts to determine if anyone else has become ill.Coronaviruses are a large family of viruses, some causing respiratory illness in people and others circulating among animals including camels, cats and bats. Rarely, animal coronaviruses can evolve and infect people and then spread between people, such as has been seen with Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). When person-to-person spread has occurred with SARS and MERS, it is thought to happen via respiratory droplets with close contacts, similar to how influenza and other respiratory pathogens spread. The situation with regard to 2019-nCoV is still unclear. While severe illness, including illness resulting in several deaths, has been reported in China, other patients have had milder illness and been discharged. Symptoms associated with this virus have included fever, cough and trouble breathing.  The confirmation that some limited person-to-person spread with this virus is occurring in Asia raises the level of concern about this virus, but CDC continues to believe the risk of 2019-nCoV to the American public at large remains low at this time.This is a rapidly evolving situation. CDC will continue to update the public as circumstances warrant.For more information about the current outbreak in China, visit: https://www.cdc.gov/coronavirus/novel-coronavirus-2019.html
CDC works 24/7 protecting America’s health, safety and security. Whether disease start at home or abroad, are curable or preventable, chronic or acute, or from human activity or deliberate attack, CDC responds to America’s most pressing health threats. CDC is headquartered in Atlanta and has experts located throughout the United States and the world.

Novel Coronavirus in China

Warning - Level 3, Avoid Nonessential Travel

Alert - Level 2, Practice Enhanced PrecautionsWatch - Level 1, Practice Usual Precautions



Key Points
  • There is an ongoing outbreak of pneumonia first identified in Wuhan, China, caused by a novel (new) coronavirus.
  • Person-to-person spread is occurring, although it’s unclear how easily the virus spreads between people.
  • Preliminary information suggests that older adults and people with underlying health conditions may be at increased risk for severe disease from this virus.
  • Travelers to Wuhan, China, should avoid contact with sick people, animals (alive or dead), and animal markets.
  • Travelers from Wuhan to the United States, and other countries, may be asked questions about their health and travel history upon arrival.
  • The situation is evolving. This notice will be updated as more information becomes available.

What is the current situation?
A novel (new) coronavirus is causing an outbreak of pneumonia illness in the city of Wuhan, Hubei Province, China. This outbreak began in early December 2019 and continues to expand in scope and magnitude. Global surveillance is in the early stages and we expect more cases to be confirmed in China and beyond its borders. Signs and symptoms of this illness include fever, cough, and difficulty breathing. Initially some patients were linked to the Wuhan South China Seafood City (also called the South China Seafood Wholesale Market and the Hua Nan Seafood Market). However, since closing the market on January 1, 2020, more cases have been identified suggesting that some person-to-person spread is occurring though it’s unclear how easily this virus is spreading between people.Coronaviruses are a large family of viruses. There are several known coronaviruses that infect people and usually only cause mild respiratory disease, such as the common cold. However, at least two previously identified coronaviruses have caused severe disease — severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). SARS-CoV and MERS-CoV have been ruled out as the cause of the current outbreak.Chinese health officials have reported hundreds of cases in the city of Wuhan and severe illness has been reported, including deaths. Cases have also been identified in travelers from Wuhan to other parts of China and other countries. This novel coronavirus has the potential to cause severe disease and death. Preliminary information suggests this is especially true among the elderly and those people with underlying health problems or compromised immune systems. Many characteristics of this novel coronavirus and how it may affect people are still unclear.In response to this outbreak, Chinese officials have started exit screening for travelers leaving the city of Wuhan and several countries and territories in the region are reported to have implemented health screening of travelers arriving from Wuhan.On arrival to the United States, travelers from Wuhan may undergo health screening, including having their temperature taken and filling out a symptom questionnaire. Travelers with signs and symptoms of illness (fever, cough, or difficulty breathing) will have an additional health assessment.

美国疾控中心给去武汉旅行者的建议
What can travelers do to protect themselves and others?

Travelers to Wuhan should
  • 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 travelers and those 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 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.


Clinician Information

Healthcare providers should obtain a detailed travel history for patients with fever and respiratory symptoms. For patients who traveled to Wuhan on or after December 1, 2019 and had onset of illness within 2 weeks of leaving, consider the novel coronavirus outbreak in China when evaluating a patient with these symptoms and notify infection control personnel and your local health department immediately.Although routes of transmission have yet to be definitively determined, CDC recommends a cautious approach to interacting with patients under investigation. Ask such patients to wear a surgical mask as soon as they are identified. Conduct their evaluation in a private room with the door closed, ideally an airborne infection isolation room, if available. Personnel entering the room should use standard precautions, contact precautions, and airborne precautions and use eye protection (goggles or a face shield). For additional infection control guidance, visit CDC’s Infection Control webpage.
