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 靠农民工购房去库存 月收入至少得够5000元 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.

Yes. There are plenty of positives: earnings, economic growth, and US tax cuts. But they are already known. Stocks look ridiculously expensive by historical standards, but that tells us nothing about short-term moves. Ultimately, it comes down to liquidity, which has driven markets since they emerged from the crisis in 2009. If all goes according to plan, central banks will be decreasing their balance sheets, and removing liquidity, by the end of 2018. If they go through with this, the odds are that the S&P will stall. But even a tiny tremor could make the bankers blink. Expect the momentum to continue.

A jailed con artist who falls in love with another inmate and escapes prison multiple times could only be the work of fiction, but this is more or less the real story of Steven Jay Russel. Much like his film counterpart, played by Jim Carrey, Russell was originally sent to prison for fraud. He escaped his first sentence to be with his partner Jim Kemple, who at the time was dying from AIDS. Russell was found two years later and returned to prison. Kemple died soon after.

单词productive 联想记忆:
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.
