Infected people without symptoms might be driving the spread of coronavirus more than we realized
Updated：March 17, 2020
New studies in several countries and a large coronavirus outbreak in Massachusetts bring into question reassuring assertions by US officials about the way the novel virus spreads.
一些国家的新研究和马萨诸塞州的一次大规模冠状病毒爆发，使美国官员对这种新型病毒传播方式的断言受到了质疑。
These officials have emphasized that the virus is spread mainly by people who are already showing symptoms, such as fever, cough or difficulty breathing.
这些官员强调，病毒主要是由已经出现发烧、咳嗽或呼吸困难等症状的人传播的。
But it appears that a Massachusetts coronavirus cluster with at least 82 cases was started by people who were not yet showing symptoms, and more than half a dozen studies have shown that people without symptoms are causing substantial amounts of infection.
但马萨诸塞州的冠状病毒群至少有82例是由尚未出现症状的人发起的，超过6项研究表明，没有症状的人正在引起大量的感染。
Until you really understand how many people are asymptomatic and asymptomatically passing the virus on, we think it's better for the entire American public to know that the risk of serious illness may be low, but they could be potentially spreading the virus to others.
在你真正了解有多少人是无症状和无症状地传播病毒之前，我们认为最好让整个美国公众知道，患重病的风险可能很低，但他们可能会将病毒传播给其他人。
