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 一线城市楼市集体降温 二三线城市有涨有跌 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.

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

11. Our gut bacteria are messing with us in ways we could never have imagined. New research has revealed that neurodegenerative diseases like Parkinson's might actually start out in the gut, rather than the brain, and there's mounting evidence that the human microbiome could be to blame for chronic fatigue syndrome. With gut bacteria showing signs of controlling our appetite, changing our brain structure, and triggering brain lesions that could lead to strokes, our tiny passengers are a force to be reckoned with.

Remedy: This is another hindsight-based regret that you can’t cure without a time machine. The years, energy and dollars you spent on your degree are sunk costs. You can’t do anything about your past academic track record, but you can identify the areas in which you think you fell short in your college days and figure out how to augment those shortcomings in the present. For example, if you feel you didn’t do enough networking outside of the classroom, you might consider joining an alumni group or make a greater effort to participate in professional associations in your field.
