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 房地产市场进入“分化” 楼市调控牵一发动全身 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

补救办法: 做预算。 如果你不能估算需要多少钱才能过上令你感到舒适的生活,你就无法确切地知道为了1万美元薪水而换工作是否真的划算。在比较新、旧工作时,列出各自的优缺点,这会对你很有帮助。如果新工作只是薪水更高一点,那么你可以比较下这个工作是否要求更长的工作时间和完成更多的工作任务。请记住,调查表明:年收入在7.5万美元以内,幸福感会随着薪水的增加而增加,但是一旦薪水超过这个水平,幸福感的增加便不再明显。因此,如果你认为薪水增加到8.5万或9万美元会使你更加快乐,这时你或许应该着手解决生活中那些与金钱无关而引起的不快乐。

"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.
