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 飞利浦/欧司朗出售照明业务 中国买家最有竞争力 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

3. Do I take time out of my day purely for myself? We all need a little “me time.” Set aside some time every day to just relax and do something that you enjoy, whether that is reading, meditating, watching TV, cooking, spending quality time with your loved ones, etc.

Actuaries put a financial value on risk for instance, the chances of a hurricane destroying a beachfront home or the long-term liabilities of a pension system. In a world awash with risks of the natural and manmade variety, the profession is booming, says Tony Lee, publisher of CareerCast.com. In addition, he says, 'there's a severe shortage of actuaries, ' so wages are rising. (The median salary for actuaries in 2010 was $87, 650, according to the Labor Department.)

A fascinating study from researchers at the University of North Florida reveals that running barefoot may actually improve your memory more than running with shoes. While most memory studies seem to take place in a laboratory or room where everyone sits at a table, this experiment definitely introduced an interesting idea to the search for a better memory. The experiment focused on something called "working memory," which is the human ability to process information and recall details throughout life. The scientists published the results of their study in "Perceptual and Motor Skills," and found that running barefoot resulted in a not-insignificant memory boost when compared with memory performance after running with shoes. The researchers found that tossing your shoes off and running for about 16 minutes at a comfortable pace could result in a 16% improvement in working memory performance.

"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
