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 坐地收租家居卖场老路走不通了 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

In March, Ford completed its exit from the luxury car market by selling Volvo to China's Geely Automobile for $1.6 billion. Although the sale represents a sharp loss - the company paid $6 billion for the Swedish automaker eleven years ago - Ford posted an annual profit of $2.7 billion in 2009, its first profitable year since 2005. Assisted by the 'Cash for Clunkers' program (not to mention Toyota's accelerator woes), Ford recaptured its position as the nation's largest carmaker in February. Which is why Ford's CEO Alan Mulally can now look abroad, including big markets like India, where it recently introduced the compact Figo.

"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.

Graham Allison, the famous Harvard professor, also warned that east Asia was headed towards the “Thucydides Trap”, adding: “When a rapidly rising power rivals an established ruling power, trouble ensues.” In early 2013, the then prime minister of Luxembourg, Jean-Claude Juncker, warned that 2013 was looking dangerously like 1913. The Economist also warned at the end of 2013, “A century on, there are uncomfortable parallels with the era that led to the outbreak of the first world war.”

BETTER CALL SAUL (AMC, Feb. 8) Vince Gilligan and Peter Gould’s “Breaking Bad” spinoff is probably the most anticipated new series of the winter. Starring Bob Odenkirk as the crooked lawyer Saul Goodman, the show is set before the action of “Breaking Bad,” so any appearances by Bryan Cranston or Aaron Paul would be cameos at best. But the audience favorite Jonathan Banks reprises his role as the phlegmatic enforcer Mike Ehrmantraut.

“Selling out!” “Pandering to the Americans!” The cries went up immediately when the official selection was announced. The list of directors crossing over to make films in English was a long one including the Italians Matteo Garrone and Paolo Sorrentino, Yorgos Lanthimos of Greece, Norway's Joachim Trier and even Guillaume Nicloux of France, a country whose cultural establishment is highly sensitive to the creeping Anglophone menace. The argument goes that Cannes is supposed to be a haven for world cinema; for English, there is Hollywood. But does it really matter? Films at Cannes in languages other than French or English play with subtitles in both languages – and that's a lot of text to deal with.
