美国有线新闻 CNN 美国48州计划放宽新冠肺炎限制措施（在线收听）

By this time next week, at least 48 U.S. states will have relaxed some of their restrictions concerning coronavirus. There's a lot of debate about this. Many health officials say opening up the country too soon could lead to more cases and deaths from COVID-19. Many business owners say keeping things closed could lead to a crash of the economy with more jobs lost. Scientists around the world are racing to test and study different medications like the one we told you about last week that could help sick people recover faster. Scientists around the world are racing to develop a coronavirus vaccine, though one of those could still be a year away or more.

到下周这个时候，美国将至少有48个州放宽因冠状病毒而实施的限制措施。目前关于这件事有很多讨论。许多卫生官员表示，过早开放国家可能导致新冠肺炎确诊病例和死亡病例增加。许多企业主表示，停工停产会导致经济崩盘，更多工作岗位流失。全球科学家正在加紧测试和研究各种药物，比如上周我们报道过的那种可以帮助患者更快恢复的药物。全球科学家也在竞相研发冠状病毒疫苗，尽管疫苗上市可能还需要一年或更长时间。

And while coronavirus testing can help officials know who's sick now, antibody testing can help them know who's had this disease in the past.

冠状病毒检测有助于官员确定目前感染的患者，而抗体检测则可以帮助他们确定谁曾感染这种疾病。

This is crucial because doctors say that up to 50 percent of the people who have coronvirus have zero symptoms when they're tested. So there could be a lot of people who have this disease or who have recovered from it without ever knowing they've contracted COVID-19 and they could have unknowingly spread it to others. We've reported that the novel coronavirus was officially identified in Wuhan, China in mid-December of last year but U.S. intelligence agencies were tracking it there in November. The first case in the United States was confirmed on January 21st. But more research is coming out that suggests it was spreading in America and other countries well before that. So antibody testing when it works accurately could supply some of the missing pieces of the coronavirus puzzle.

这一点至关重要，因为医生表示，多达50%的冠状病毒感染者在接受检测前没有任何症状。因此，可能有很多感染者或康复者根本不知道自已感染了新冠肺炎，而他们可能在不知情的情况下将病毒传染给其他人。我们此前报道过，去年12月中旬，中国武汉正式发现了新冠病毒，但美国情报机构在11月就追踪到了这种病毒。美国于1月21日确诊首例病例。但越来越多的研究表明，早在那之前，该病毒就传播到了美国和其他国家。因此，如果抗体检测结果准确，那其可以弥补冠状病毒谜团中缺失的部分。
