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 楼市政策储备应防患于未然 做深做实楼市调控 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.

补救办法:这也是一个后知后觉的遗憾,没有时间机器是无法解决的。你在学业上花费的时间、精力和金钱是既定成本。你无法改变以前的学业情况,但可以找出自己在大学期间没有学好的课程,然后想办法从现在开始弥补。例如,如果你觉得自己在课堂外的社交有所不足,你可以考虑加入校友协会,或者努力地融入到你所在领域的行业协会。如果你后悔错过了早上八点钟的管理会计课程,悲叹这些知识现在对你多么重要,那么你可以看看附近社区大学的这类课程。

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. If you regret skipping your 8:00 AM managerial accounting class and mourn how useful those concepts would be to you now, check out the continuing ed options at your nearest community college.

Remedy: When we make a major decision such as accepting (or turning down) a job offer, we tend to exercise confirmation bias. If we think we made a good choice, we prioritize information that supports this view and if we fear we’ve made a mistake, we zero in on intel or impressions that reinforce this gut feeling. If you habitually doubt your competence when it comes to making career decisions, the issue is less about the subjective quality of your past choices and more about building confidence in your ability to guide your career in a satisfying direction and exert some degree of control over the outcomes of your choices. Addressing this could involve recalling the circumstances under which you made a particular choice and the priorities you held at the time and noting how they differ from the circumstances and priorities under which you’re evaluating those decisions. It could also involve working with a career coach to identify patterns in your decision-making and to help you bolster areas in which you’d like to increase your confidence – risk taking or negotiation, for example.
