美媒解读第二波疫情风险：从哪来？怎么防？

5.What are the prospects for second waves of coronavirus?

发生第二波新冠疫情的可能性有多大？

There have been hints that a second wave is a risk. Some areas that were shut down by the virus and then reopened had restrictions reimposed because of new cases. Much of the rest of the world is still struggling to get the current wave under control. Most areas that have contained the virus have done so using movement restrictions, which slow the virus’s spread but leave many people vulnerable to infection once they begin to venture out again, raising the prospect of second waves.

有迹象表明，可能会出现第二波疫情。由于出现新发病例，此前因新冠病毒而封锁、随后重新开放的一些地区再次实施了限制措施。其他许多国家仍在努力控制当前这波疫情。大多数已经控制住该病毒的地区采取了行动限制措施，它减缓了病毒传播，但使得许多人在恢复外出时容易受到感染，从而增大了暴发第二波疫情的可能性。

6.What could prevent them?

如何能阻止第二波疫情？

The WHO has recommended lifting movement restrictions in stages to test the effect of each before moving to greater openness. In any case, experts say, the key to keeping infections low without locking down everyone is to scale up testing and contact tracing. Health authorities need to find infected people, isolate them, and identify their recent contacts, so they can be tested as well and isolated if necessary. Eventually, it’s possible that enough people will become exposed to the coronavirus that herd immunity will develop and it will stop spreading, or that a vaccine against it will be licensed.
