The World Health Organization declared the coronavirus outbreak a global emergency Thursday after the number of cases spiked tenfold in a week, calling it an “extraordinary event” that endangers countries outside China and requires a coordinated international response.

This new declaration—made Thursday at the organization’s Geneva headquarters—will lead to more travel and trade restrictions on China. Already many companies in the US have shuttered their China offices, while airlines are canceling direct flights.
