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 后五一装修季 看市场中那些靠谱好涂料 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 first drone can be traced back to 1916 when British inventor Archibald Low designed and flew the first unmanned radio-controlled vehicle. The drone was made to counterattack German Zeppelin airships, and it also carried out ground attacks during World War I. It was made with wood and tin, its wings taken from the lower wing of another biplane. Overall, the drone was somewhat unsuccessful because the noise from its engine interfered with its radio. The Sopwith Aircraft Company also tried making a drone in 1916. They placed the radio equipment at the tail so that the engine would not interfere with its signal, but their drone never flew as it was damaged in an accident on the ground. Low would try flying his drone again in 1917 when he flew it in front of some senior military officers. It was launched from the back of a lorry and flew for some time before crashing due to engine failure, almost killing the military officers present.

Remedy: While the idea of being your own boss is an attractive one, not everyone is cut out to be an entrepreneur. Being responsible for your own success, creating a legacy for your family and improving the lives of clients and customers certainly sounds romantic, but what about the long hours, the lack of leisure time, the risk of financial failure, the fact that you’re the boss, entry-level employee, marketer, accountant and janitor all rolled into one? If you value job stability, prefer a singular focus over multi-tasking, aren’t particularly comfortable with risk and can’t imagine yourself hustling for new business on a daily basis, the entrepreneurial lifestyle isn’t for you.
