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 部分上市公司折价甩卖房产 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.

Back in the movie wasteland of last January, no one could have guessed what a bounty of good films the year would bring. Not just good films, but several that measure up to our idealized notions of what the medium once was. Two candidates for the top of the heap pretty much chose themselves. For sheer entertainment, the clear call is 'American Hustle,' David O. Russell's joyous celebration of 1970s-era con artists and their intricate cons. For innovation-a new theatrical experience born of new technology-'Gravity' whirls in its own orbit. With the understanding that there's nothing to be said against 'American Hustle,' and everything to recommend this screwball comedy for the ages, I think 'Gravity' is the best movie of the year.
