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 上海一小区鸽棚“钉子户”屡拆屡建 邻居不堪其扰向12345市民服务热线投诉 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.

Goldie Blox是一家玩具公司,使命是重新定义玩具商店中的“粉红走道”。在科学、技术、工程和数学(STEM)教育和职业领域,男性数量要大大多于女性,大部分女孩往往在八岁前就对这些领域失去了兴趣。Goldie Blox所设计的玩具则通过吸引女孩发展强大的口头及故事讲述能力的方式——同时仍提供机会来发展日后可转化成对工程学兴趣的技能——来鼓励和启发未来的工程师们。说到机会,一家玩具初创企业如何能在和一开始就统治着玩具行业的大公司的抗衡中脱颖而出呢?Goldie Blox走出了明智的一步:最近,该公司发布了一段视频,采用了Beastie Boys的歌曲《女孩们》(Girls)做背景音乐,该视频得到了病毒式传播。尽管这段视频最终被撤下,但Goldie Blox在提高公众对让更多女性和女孩对STEM产生兴趣——以及对Goldie Blox玩具——的认知上,做了一份相当不错的工作。
