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 京津冀“大棚房”有七成占用耕地 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

With a bit of help from Charles Dickens, let’s take a look back at the year in which almost nothing worked:
The Man Who Knew, by Sebastian Mallaby, is the 12th winner of the £30,000 award, which goes to the “most compelling and enjoyable” title of the year.

'Nebraska' gets to the heart of Bruce Dern's prickly old geezer, Woody Grant, by way of a road trip across Montana and Nebraska, shot in radiant black-and-white. (Here again one of the movie's stars is its cinematographer, Phedon Papamichael.) Alexander Payne directed, flawlessly, from Bob Nelson's stellar script, which is all about thwarted love, and reconciliation, between Woody and his son Will; he's played with painfully quiet eloquence by Will Forte. Here's the American heartland as it's seldom portrayed on screen, with humor and almost palpable fondness.

"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.

Canadian border agents are handing people entering Canada a sheet from the Public Health Agency of Canada that instructs them to self-quarantine for 14 days and monitor themselves for any symptoms that might signal COVID-19. Selena Simmons-Duffin/NPR hide caption
