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 宁夏鼓励本土企业挂牌上市 最高奖励1000万元 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

"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.

No. What has been billed as the largest ever IPO is a cornerstone of de facto leader Mohammed bin Salman’s grand economic restructuring, so it must happen. Shares in Aramco will be quoted on the local stock exchange. The international element of the IPO is unlikely to be a public listing, however. Donald Trump has lobbied for New York, and London is pulling all the stops. Hong Kong and Tokyo are also under consideration. But the Saudis will opt instead for a private sale, or choose to list internationally later than anticipated.

在外界看来,中国的经济实力还在从未经历文化大革命的年轻一代中,激发起民族主义情绪。北京方面在对待海上主权争议时的强硬回应,在本已对中国经济实力产生戒心的亚太区加剧了各方对中国军事目标的担心。这也是促使日本决定放松武器出口禁令的原因之一;令中国沮丧的是,其行为还推动邻国支持美国加强自己在亚洲的存在,并使得地区贸易一体化变得复杂。
《巴克斯托姆》(Backstrom),Fox,1月22日播出。去年,福克斯推出根据一部澳大利亚电视剧《法庭浪子》(Rake),由格雷格·金尼尔(Greg Kinnear)主演,讲述一个自毁律师的故事。那部剧没成功,但现在Fox又试着推出了一部根据瑞典系列小说改编的自毁侦探的故事,由《办公室》(The Office)男星雷恩·威尔森(Rainn Wilson)主演。这部剧由Fox的系列剧《识骨寻踪》(Bones)的编剧哈特·汉森(Hart Hanson)主创,但在试播集里,威尔森饰演的巴克斯托姆看上去更像豪斯医生(House),而不像《识骨寻踪》里的角色。
