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 公租房违规转租为何屡禁不止 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

Though the Dutch financial markets then had none of today’s technology, they employed many of the same practices that traders use today. Investors bought securities, sometimes borrowing money with loans secured by the shares they were buying. In today's language, they bought shares on margin. Lenders protected themselves by demanding a “haircut” – collateral in cash or securities that exceeded the loan amount by a specified percentage. If the value of the securities dropped below that specified percentage, the lender would demand that the investor put up additional money to stay in line with the haircut. If the investor couldn’t come up with the added margin, the lender was entitled to liquidate the securities and recoup the loan amount.
In the past decade, only three blue diamonds of 10 carats or more with the same vivid grading for intensity have been sold at auction, all weighing less than 12 carats and none flawless, he said.
In global health, 2016 will be remembered as the year a little known virus made a major impact. It felt strangely familiar, but this time it wasn't Ebola making headlines around the world, it was Zika - a mosquito-borne virus being linked to a huge spike in the number of babies in Brazil born with brain defects.

"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.
Yes — by an eyelash. Democrats will need to win an additional 24 seats, meaning they will have to hold on to all 12 Democratic districts that Mr Trump won last year and pick up the 23 Republican districts that voted for Hillary Clinton, plus one or two more for good measure. The math is not on the Democrats’ side, but history is. The president’s party almost always loses some House seats in the midterms, and sometimes loses big, especially when the president has an approval rating below 50 per cent. See Barack Obama in 2010.
It even featured in the March 19, 1870, issue of Scientific American magazine. Made by Thomas Luders from Olney, Illinois, and called a "pedespeed," the wheels then were much smaller, measuring around 36 centimeters (15 in) in diameter. Luders also said the skates could be used by anybody, irrespective of their physique. He himself was a large, heavy man, and he claimed he could use them for two straight hours without getting tired. Another version of wheel skates, appearing in 1923, had its tires on the inside of the foot rather than outside. (Other than the size of the wheels, the main improvement made by Chariot Skates is the small tire at the back of the bigger tire for increased stability.)
According to the Chinese Academy of Social Sciences, China's migrant workers account for around 50 percent of the labor force in industrial and related sectors. Yet they don't enjoy equal rights as city dwellers because of household registration requirements.

Statistics show global research and development expenditure grew at an annual pace of approximately seven percent before 2009, but slowed down to four percent in 2014
In fact, one ancient saying was, "ifyou have Kucha, only one percent of the states in the Western Frontiers remain unsubmissive."
That pushed the state share of total investment for the year to date down marginally to 36.6 per cent, still the largest share since 2011 and reflecting the outsize role of government spending in sustaining economic growth during 2016.
