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:

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.
What can travelers do to protect themselves and others?
Travelers to Wuhan should
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).
