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 索菲亚家居回应“799套餐”致客单价下降:已做调整应对 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

What Mr Ravenscroft liked about it when he was choosing his graduate career path was that it of-fered the best of two worlds.

"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 rough edges of the mountains, the heavy hail storms in the middle of the afternoon, were "inconvenient" but added to the beauty of the trek. I am acutely aware now that in my pursuit of perfection at work, I have often failed to recognize that imperfections are also a core part of our identity that needs to be preserved and not always changed.
