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 元宵节电商大数据:汤圆销量翻25倍 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

Denmark, for instance, is 88 percent white Danish today — hardly a majority in jeopardy. But a generation ago, in 1980, it was 97 percent white. The anti-immigrant Danish People’s Party is now the second-largest party in the Danish Parliament. In Germany, where the foreign-born population shot up by approximately 75 percent between 2011 and 2015, the anti-immigrant, populist Alternative for Germany party is now drawing record support.
Nicolas Cage certainly bucks a lot of trends. He once told media that, for residency reasons, the award he won for the 1996 film Leaving Las Vegas was “in a truck somewhere moving through Louisiana”. Apparently, one of the ways the authorities determine if you’re a resident or not – in what must be the most niche of tests – is to ask where your Academy Award is.

"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.

On the long voyage to World Cup triumph, Belgium and Uruguay are two icebergs that the favorites would rather avoid. Both nations, despite being underdogs in this year's tournament, have the ability and the nous to upset their bigger and brasher rivals.

这首歌简直太好听了。感情丰沛、大气磅礴,阿黛尔为《大破天幕杀机》演唱的主题曲令人拍案叫绝。这首歌让人们对詹姆斯·邦德留下了独特的印象,人们以后还能借由这首主题曲重拾对詹姆斯·邦德的记忆。尽管历史和原有的情感使其他两首歌的排名高于这首歌,但是至少在我们看来,阿黛尔的《天降杀机》和前两名相差无几。

Though the Dutch financial markets then had none of today’s technology, they employed many of the same practices that traders use today. Investors bought securities, sometimes borrowing money with loans secured by the shares they were buying. In today's language, they bought shares on margin. Lenders protected themselves by demanding a “haircut” – collateral in cash or securities that exceeded the loan amount by a specified percentage. If the value of the securities dropped below that specified percentage, the lender would demand that the investor put up additional money to stay in line with the haircut. If the investor couldn’t come up with the added margin, the lender was entitled to liquidate the securities and recoup the loan amount.
