中国爆发冠状病毒导致美国官员在三个主要机场筛查高危乘客，以减少病毒传播。
中国当局报告称，已经有200多例冠状病毒病例，至少3人死亡。随着疾病在中国境外蔓延，世界卫生组织(世卫组织)将于周三召开紧急会议，以确定疫情是否构成国际紧急情况。
根据，这种特殊的病毒株以前还没有在人类身上被发现世卫组织，并已传播到日本和韩国。周五，疾病控制和预防中心宣布，三个机场的某些乘客将接受健康检查，以发现患病旅客。
“根据目前的信息，2019-nCoV对美国公众的风险目前被认为很低。然而，疾控中心正在采取积极的防范措施声明。
谁将被筛选？
疾病预防控制中心表示，筛查将仅限于从病毒发源地中国武汉直飞或转机前往美国的乘客。官员们将只在旧金山国际机场、纽约约翰肯尼迪国际机场和洛杉矶国际机场测试乘客，因为他们接待的武汉游客最多。
症状是什么？
抵达机场的乘客将被测体温，并被要求填写症状问卷。该病毒的症状包括发烧、咳嗽和呼吸困难，在机场发现有这些症状的旅行者可能会接受额外的健康评估。
周六，洛杉矶对武汉来的旅客进行冠状病毒健康检查的第一天，中国国际航空公司的一架从北京飞往洛杉矶的航班着陆后，人们抵达洛杉矶国际机场。
什么是冠状病毒？它是如何传播的？
冠状病毒是从普通感冒到严重呼吸道疾病的病毒家族的一部分疾病控制中心。这种特殊的病毒株会导致一种肺炎，并被认为是通过动物和人类接触传播的。
许多患者与武汉的海鲜和动物市场有关联，导致人们相信病毒最初是从动物传播到人的。疾病预防控制中心报告称，一些患者没有接触过动物市场，这表明病毒也通过人类接触传播。
在更严重的情况下，冠状病毒会导致肺炎、肾衰竭和死亡。据报道，目前冠状病毒的三名受害者都曾患病NPR。
根据，对遗传密码的分析显示，这种病毒最像严重急性呼吸系统综合症英国广播公司。非典于2003年2月首次在亚洲被报道，并在被遏制之前传播到了20多个国家疾病控制中心报道。爆发期间，至少有8000人感染了非典，近800人死亡。
冠状病毒可以治疗吗？
冠状病毒没有特定的治疗方法，根据世卫组织玛丽亚·范克尔霍夫博士。然而，每种病毒的特定症状都可以治疗。
如何预防感染？
人们可以通过遵循基本的手和呼吸卫生来帮助保护自己免受感染，例如用肥皂和水洗手，打喷嚏到肘部。克尔霍夫说，人们还应该确保所有肉类在食用前都经过适当烹饪，避免与活的动物发生不必要的接触。
PASSENGERS TO BE SCREENED FOR NEW CORONAVIRUS AT THREE MAJOR U.S. AIRPORTS—HERE'S WHAT YOU NEED TO KNOW
Acoronavirus outbreak in China is causing officials in the United States to screen at-risk passengers at three major airports in an effort to reduce the virus from spreading.
Chinese authorities reported there have been more than 200 cases of coronavirus and at least three deaths. Following the disease spreading outside of China's borders, the World Health Organization (WHO) will conduct an emergency meeting on Wednesday to determine if the outbreak constitutes an international emergency.
This particular strain of the virus has not been previously identified in humans, according to WHO, and has spread to Japan and South Korea. On Friday, the Centers for Disease Control and Prevention (CDC) announced certain passengers at three airports would undergo health screenings to detect ill travelers.
"Based on current information, the risk from 2019-nCoV to the American public is currently deemed to be low. Nevertheless, CDC is taking proactive preparedness precautions," the CDC said in a statement.
Who Will Be Screened?
Screenings will be limited to passengers traveling to the United States on direct or connecting flights from Wuhan, China, where the virus originated, according to the CDC. Officials will only be testing passengers at San Francisco International Airport, John F. Kennedy International Airport in New York and Los Angeles International Airport because they receive the most travelers from Wuhan.
What Are the Symptoms?
Passengers arriving at the airport will have their temperature taken and be asked to fill out a symptom questionnaire. Symptoms of the virus include fever, cough and difficulty breathing and travelers found to be experiencing these symptoms at the airport may undergo an additional health assessment.
People arrive to Los Angeles International Airport after touchdown of an Air China flight from Beijing, which serves as a connector from Wuhan, China, to Los Angeles, on the first day of health screenings for coronavirus of travelers from Wuhan on Saturday in Los Angeles.
What Is a Coronavirus? How Does it Spread?
Coronaviruses are part of a family of viruses that range from the common cold to severe respiratory diseases, according to the CDC. This particular strain of the virus causes a type of pneumonia and is believed to spread from animals to humans and through human contact.
Many patients had a link to a seafood and animal market in Wuhan, causing the belief that the virus initially spread from animals to people. Some patients haven't had any exposure to the animal market, which, the CDC reported indicates the virus is spreading through human contact, as well.
In more severe cases, coronaviruses can cause pneumonia, kidney failure and death. All three victims of the current coronavirus had prior illnesses, according to NPR.
Analysis of the genetic code showed the virus most closely resembles severe acute respiratory syndrome (SARS), according to BBC. SARS was first reported in Asia in February 2003 and spread to more than two dozen countries before it was contained, the CDC reported. At least 8,000 people became sick with SARS during the outbreak and nearly 800 people died.
Can Coronaviruses Be Treated?
There isn't a specific treatment for coronaviruses, according to Dr. Maria Van Kerkhove at WHO. However, specific symptoms of each virus can be treated.
How Can You Prevent Infection?
People can help protect themselves from infection by following basic hand and respiratory hygiene, such as washing hands with soap and water and sneezing into elbows. People should also ensure all meat is properly cooked before consumption and avoiding unnecessary contact with live animals, according to Kerkhove.
