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 广州将实施租赁房试点 小升初摇号或借鉴外地经验 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.

Rafael Corrales, a partner at Charles River Ventures, believes that the growth in a wide range of fields—from academia to infrastructure to policy—is a sign that 2014 was the biggest year bitcoin has had yet, despite its volatility. “In the short-term, that’s an easy knock from people who don’t understand or believe it can be something,” he says. “It’s the easiest thing for them to go after. In that transition stage, you’re going to have extreme volatility, so looking at its value over one year is kind of silly.” As for occasional hacks, he adds, “There are going to be bumps in the short term, but they’ll be solved sooner than later. And these things are being addressed by a huge community of people. So you have to be really excited, despite small bumps.”

For now, most of the activity around bitcoin is monetary in nature, so it makes sense that its critics point to volatility. Though the value of one bitcoin in U.S. dollars has fallen 67% in the past year, its value over the past two years is up 1,879%, according to the market price chart at blockchain.info. So whether it’s a good investment or a bad one is a matter of perspective.
