好奇， 刚查了下CDC的隔离guidance， 居然是test positive 后五天隔离就可以了。。而不是症状消失之后还隔离五天？ 不少人症状还要一两周结束呢。。 这个rule感觉对之前的疫情是推波助澜的作用啊。。。病毒难道不是有症状的时候就有传播性么？ “If you test positive, you should isolate for at least 5 days from the date of your positive test (if you do not have symptoms). If you do develop COVID-19 symptoms, isolate for at least 5 days from the date your symptoms began (the date the symptoms started is day 0).”
