The US Centers for Disease Control and Prevention has issued the first federal quarantine order in more than 50 years for 195 Americans who were evacuated out of Wuhan, China, the epicenter of the 2019 novel coronavirus outbreak (2019-nCoV)
The US citizens will be held under quarantine at the March Air Reserve Base in California, where they arrived from Wuhan on Wednesday, January 29 on an aircraft chartered by the US State Department. They have remained at the base since then. The quarantine will last 14 days from the time that their flight left Wuhan. Fourteen days is considered the likely maximum time of a 2019-nCoV infection incubation period—that is the time between an exposure and onset of symptoms.
The decision to issue a quarantine comes amid the continued spread of 2019-nCoV—both within and beyond China. It also comes on the heels of a report that an asymptomatic infected person from China spread the viral illness to a 33-year-old healthy business associate in Germany. Further testing found that three other associates at the same company in Germany had also contracted the infection. All four cases were mild, and the first infected associate, who noticed symptoms on January 24, started feeling better and returned to work on the 27. The report was published yesterday, January 30, in the New England Journal of Medicine.
