CNN10分钟新闻主持人卡尔·阿祖兹：目前美国约有349,462,000人口，其中约80%被要求待在家中。

I'm Carl Azuz. Welcome to CNN 10.

我是卡尔·阿祖兹。欢迎收听CNN10分钟新闻。

Stay at home, shelter-in-place, self-isolation, social distancing — these are all terms pretty suddenly being used worldwide. They're defense measures against the spread of coronavirus. Authorities from federal governments down to local ones are trying to encourage people to avoid others as much as possible.

居家、就近防疫、自我隔离、保持社交距离——这些都是全世界突然开始使用的术语。这些是防止冠状病毒传播的防御措施。从联邦政府到地方政府，有关部门都在试图鼓励民众尽量避免接触他人。

Many continue to ignore these orders and one reason why health officials are so angry about that is because of this. While some people who contract COVID-19 have severe and deadly symptoms, others have absolutely none at all.

但是依然有许多人无视这些命令，而令卫生官员对此大为恼火的一个原因是：虽然一些新冠肺炎感染者会出现严重或致命的症状，但另一些感染者则完全没有任何症状。

In Iceland, a country that has reported more than 1,200 cases, half of those who tested positive for coronavirus say they've had no symptoms.

冰岛报告了超过1200例确诊病例，而该国在冠状病毒检测中呈阳性的人中，有一半表示自已没有出现任何症状。

In the United States where there been over 200,000 cases, government health officials estimate that 25 percent of them have no symptoms. So, it's a situation where tens of thousands of people are carrying the virus and possibly spreading it without even knowing it.

美国的确诊病例已超过20万例，政府卫生官员估计，其中25%没有症状。因此，这意味着有成千上万的病毒携带者可能会传染他人，但他们自已却毫不知情。

So, now, the U.S. government is considering a recommendation that the general public wear face masks as long as there are still enough for the health care workers who need them. There are currently shortages in many American hospitals.

因此，美国政府正在考虑建议公众佩戴口罩，前提是先满足更需要口罩的医护人员的需求。目前美国有多家医院面临医疗物资短缺。

What's interesting about this is that the World Health Organization, part of the United Nations, has said it doesn't have evidence that masks will protect the general public. But a top American health official says something doesn't have to be 100 percent effective to have some benefit.

而值得注意的是，联合国下属机构世界卫生组织表示，目前没有证据证明口罩能保护公众。但一名美国卫生官员表示，有些东西并不是100%有效才算有用。
