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 今日起首批4851套公租房面向广州户籍家庭开放登记 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.

今年选股遇到困难,部分原因在于市场顶部高度集中。苹果、伯克希尔o哈撒韦、强生、微软和英特尔这五只股票占去了市场涨幅的20%。如果你未持有上述股票,几乎就没有机会分享这场增长盛宴,而正是这几家公司的增长推高了标普500指数。市场上大部分股票的表现要逊色得多。研究公司路佛集团称,标普1500综合指数成分股中,仅有30%的个股跑赢了该指数。上次出现这样的景象,那还是1999年的事。

Market watchers were forced to digest the reality of negative 2.9% GDP for the first quarter of the year. All of a sudden, everyone’s forecasts seemed too rosy—or at least too smooth—compared to the lumpy reality. This led to a raft of second-guessing on the timing of the Fed’s eventual exit from its bond-buying stimulus program. We went from confidence to WTF? in a space of a few weeks, with all the asset class rotations and market corrections that come along with a fresh bout of uncertainty.

No. The Bank of Japan’s life will get tougher in 2018 as the US Federal Reserve tightens policy and widens the interest rate gap with Japan. But governor Haruhiko Kuroda is determined to hike rates in response to one thing only: inflation. The BoJ may let the yield curve climb a little if prices start to accelerate, but real interest rates in Japan will end 2018 no higher than at the start of the year.
