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 多数商家已走出“春节时间” 建材等行业仍在休假 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.

‘The Good Wife’ Once Will (Josh Charles), Alicia’s illicit love interest, died at the end of Season 5, this sexy CBS courtroom drama seemed as if it might droop and wither, but instead, the sixth season steamed with almost madcap energy, mixing Alicia’s newly fledged political campaign, a war of the roses between Alicia’s new firm and her old one, and the legal travails of Cary, her legal partner. Alicia isn’t quite so good anymore, and that makes “The Good Wife” all the better.

In addition, you can set up recurring reminders, which are perfect for remembering to mail estimated quarterly tax payments, renewing subscriptions, running payroll and other things you tend to forget.
