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 融资收紧出货受限 京沪深房价环比负增长 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

首先,Bitstamp遭遇黑客袭击,以及2011年黑客袭击比特币交易平台Mt. Gox(此次黑客袭击要严重得多,其损失当时约合4亿美元),往往被误解为比特币本身存在安全问题。但事实上,这只能表明上述比特币交易平台存在缺陷,而非比特币技术本身存在问题。而最令人激动的,正是比特币背后的底层技术。正如《财富》杂志2015年1月刊《打造未来》系列报道中所写,大部分极为看好比特币、为其大声疾呼的狂热粉丝(包括马克o安德森这样的大牌企业家,也包括花大把时间更新比特币REDDIT页面的开发者和比特币“矿工”),更感兴趣的是能建立在比特币“区块”(该货币基本骨架)上的应用,而非比特币货币体系。两个实体间可通过“区块”安全交换任何形式的价值。

"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

For starters, breaches like that of Bitstamp and the much larger (valued at about $400 million at the time) 2011 hack of the exchange Mt. Gox are often misconstrued as security issues with the currency itself. But they are only signs of flaws in those particular exchanges and not a sign of an issue with the underlying technology. And it is the underlying technology behind bitcoin that most excites. As we wrote in the “Shape the Future” package of our January 2015 issue, most of the vocal enthusiasts so bullish on bitcoin—from big-name entrepreneurs like Marc Andreessen to the developers and miners who spend their days refreshing the bitcoin Reddit page—are more interested in the applications that can be built on bitcoin’s “block chain,” the currency’s foundational backbone, than they are in bitcoin as a monetary system. The block chain allows the secure exchange of any form of value between two entities.
