To stop the spread of the coronavirus, health officials have a favorite refrain: After being in a city or region where there have been a lot of COVID-19 cases, spend 14 days in quarantine even if you feel perfectly fine — don't leave your house. Coming from New York? 14-day quarantine. Arriving in Hawaii? 14-day quarantine. Been in Italy or China or Iran recently? 14-day quarantine.

"That's a long-standing public health practice, and it's called 'traveler's quarantine,' " explains Lindsay Wiley, a professor at American University's Washington College of Law. "Fourteen days is not a made-up number here — it's based on what we know so far about COVID-19, and it's possible that over time we'll see that number change as we learn more [about the virus]."

The 14-day rule is widespread because public health agencies around the world work together on these guidelines. In the U.S., the 长租公寓真的爆仓了 杭州鼎家破产4000户租客受损 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

可以这样说美国银行首席执行官布莱恩?莫尼汉这个人:他很会说话。在给股东的信中,莫尼汉特地感谢美国纳税人,正是由于他们,美国银行才获得了450亿美元的不良资产援助资金。他还说自己如今正在金融改革方面同“政策领导人”紧密合作。不过他是否能做好,比如转变美国银行的境遇,就是另外一回事了。虽然美国银行的确在去年12月偿还了援助资金,但是它仍然有数十亿美元的高风险住房与商用房房贷,这也是为什么它要在年度报告中花8000字来讨论风险了。

"The incubation period varies from virus to virus and sometimes from host to host," says Rachel Graham, a virologist at the University of North Carolina's Gillings School of Global Public Health.

For the virus that causes COVID-19 — its official name is SARS-CoV-2 — researchers have found that the typical incubation period is about five days. About 97% of the people who get infected and develop symptoms will do so within 11 to 12 days, and about 99% will within 14 days.

Rafael Corrales, a partner at Charles River Ventures, believes that the growth in a wide range of fields—from academia to infrastructure to policy—is a sign that 2014 was the biggest year bitcoin has had yet, despite its volatility. “In the short-term, that’s an easy knock from people who don’t understand or believe it can be something,” he says. “It’s the easiest thing for them to go after. In that transition stage, you’re going to have extreme volatility, so looking at its value over one year is kind of silly.” As for occasional hacks, he adds, “There are going to be bumps in the short term, but they’ll be solved sooner than later. And these things are being addressed by a huge community of people. So you have to be really excited, despite small bumps.”

你可能觉得我们对于列清单的爱好是从“十诫”继承而来,但安伯托·艾柯( Umberto Eco)的说法却正相反,“清单是文化的起源”,他写过一本书,《无限的清单》(The Infinity of Lists),书中在讨论自己熟悉的东西时这样说道。而且,文化希望“让无限变得可以理解”,并且“创造秩序——不是永远如此,但通常都是这样”,所以才有了荷马在《伊利亚特》中的人名清单,以及你冰箱上贴着的,永远做不完的家务清单。“我们喜欢清单,因为我们不想死,”艾柯还说,这可能是对“清单体”(listicle)的最佳解释了。
