“在出现极少数确诊病例后，卫生官员就开始严格追踪接触者。不到一周的时间里对1000多万人进行了检测，生活似乎很快就回到了正常状态。” "After only a handful of confirmed cases surfaced, health officials began strict contact tracing and tested more than 10 million people in less than a week. And life seems quickly returned to newer normal again."
卡尔弗表示，这种正常状态主要只发生在中国国内，“就像在保护罩里一样。” 他表示，对于生活在世界其他地方的人们，“由于新冠病例再次激增，他们唯一的期望可能就是疫苗了。” "For some whose livelihood is ruled in the other parts of the world, for cases are surging once again, their only hope may be the vaccine."
