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 东海利用大数据改革办证流程 二手房交易一小时内领证 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

Ahh, the glamorous life of AT&T: best friends with Steve Jobs, exclusive rights to the iPhone (for now) and carrier of choice on the iPad. So why, with everything going for it, did the stock miss a huge rally? In the year ending April 1, Apple soared 109% and the S&P 500 rose 41%. AT&T? Down 2%. The problem is growth, or lack thereof: little in its saturated wireless business and a decline in landlines, which still accounts for 25% of sales. Unless its high-speed Internet business takes off or the iPad drives new wireless growth, the beatings by Wall Street will continue.

"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.
