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 房企销售数据虽“靓”或难撑股价 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

Participants in the study were between the ages of 18 and 44 and were asked to run twice – with and without shoes. After completing their quick runs, researchers found that the heart rate and overall run speed of each participant had no effect on memory, but the presence of shoes or bare feet did. The researchers have hypothesized that the need to engage the mind while running barefoot to avoid pebbles or other impediments could have a positive impact on a person's ability to remember things. If you're an adventurous person, you might try taking a barefoot jog around the block before your next test or before you need to remember something important.

"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 stories are wildly unrealistic, but they carry an inkling of truth between their pages. While these are some of the most interesting films out there, viewers often don't even know that what they're watching really happened. Well, wonder no more! Keep reading to learn about some of Hollywood's zanier scripts that took their inspiration from good old-fashioned real-life drama.
