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 2016年家居建材行业发展趋势预测:刚需或成市场主流消费 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

The Great Recession had devastating effects across the U.S. and few places were as hard hit as Arizona. The state was booming on the strength of its tourism and real estate markets during the 2000s. Median home prices jumped 70% between 2003 and 2006—only Nevada had bigger gains—fueling more building and construction jobs. Monthly unemployment was at 3.5% through much of 2007. But then the bottom fell out. Home prices plummeted more than 50% from their peak and 6% Arizona properties received foreclosure filings in 2009. Unemployment stubbornly remained in double-figures for most of 2009 and 2010 and only Nevada lost a higher percentage of jobs over the last five years. Household incomes declined at the fastest rate in the country since 2008.
