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 中国各地城镇化潜力不一:河南、湖南位居前两位 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

Fund shareholders weren’t wasting any time reacting to this year of disappointment. Collectively, they’ve added just $35 billion to active stock-picking funds in the last 11 months, less than a quarter of the $162 billion they added in 2013, which was the first year of positive flows for the industry since 2007. This is not to say that they were sitting still. ETFs and passive index funds took in over $206 billion in net deposits through Thanksgiving, and Vanguard surpassed the $3 trillion mark sometime in late summer. Investors seem to have decided that they’d rather bet on the horses than the jockeys, after all.

"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.

As we pointed out earlier, we've long been able to restore hearing to the deaf, but restoring sight to the blind is a much more complicated matter. When people lose their sight, their retinas no longer send signals from their photoreceptors to their brains. To make an artificial eye, we'd need to understand how the retina processes those signals, and that's a code scientists just haven't been able to crack.
