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 陶瓷卫浴频陷“假冒门” 家居卖场竟“被”开网店 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.

Rogers, unhappy with the turn of events, decided to leave the show after the first three seasons. The breach of contract led to a multi-million dollar lawsuit. Ironically, Wayne Rogers had never signed his contract to begin with (he had a problem with a morals clause). The lawsuit was thrown out. You could say Rogers got the last laugh, but since M·A·S·H went on for eight more seasons and Rogers' never reached the same career success again, the last laugh might be a relative concept.

自迈克尔?哈内克之后,再没有人像希腊导演欧格斯?兰斯莫斯那样喜欢在电影作品中解剖社会习俗了。两年前,他的电影《龙虾》用其看待社会的辛辣视角完全征服了戛纳电影节。在《龙虾》描述的社会中,如果成年人无法在45天内寻找到一个爱侣,就会变成动物——这也是我们的世界,只是将集体思维和从众性推向了最大的极限。如今他又带着新作《圣鹿之死》回归,这是关于一个外科医生(科林?法瑞尔饰)和他的妻子(妮可?基德曼饰)的家庭惊悚电影。这位妻子也是一个医生,她像朋友一样对待没有父亲的少年马丁。马丁似乎决心暴露这个家庭的秘密,并揭开这对夫妻过去的一段可怕的创伤。这部电影想表达的难道是家庭(也有可能是社会)的平静有时候依赖于共享商定的谎言?不管是不是,准备好接受惊吓吧。该片将于11月9日在丹麦上映,11月16日在俄罗斯上映,11月30在中国香港上映。(A24制片公司)

It was the first "real" James Bond song (again, the first two films only opened with orchestral music), and it's still the best. Shirley Bassey got an opportunity to sing her soul out and she accepted the challenge with obvious pleasure. This is a song that makes the villain Auric Goldfinger seem a lot more threatening (and attractive) than he actually is, but that's part of the miracle of Bassey's work here. It's proud and heroic and enticing and it's kind of a lie, but who cares? The music is pure James Bond, the lyrics are pure machismo, and the performance is perfect.

1. Beyoncé “Beyoncé” (Parkwood Entertainment/Columbia) An ambush that landed after last year’s tabulations, Beyoncé's tour de force — a lustrous showcase of soulful dominion, sleek production, sensual abandon and feminist agency, not always in that order — kept its relevance during a long year swollen with distractions. The singing, like the attitude, is phenomenally assured yet full of nuance; the message is complicated but clear. It’s high-wire pop that refuses to pander.
