A small town in central Canada that is host to the country's largest air force base is preparing, with some apprehension, for the arrival of some 200 evacuees from Wuhan, China, the epicenter of a coronavirus outbreak.

Canada plans to fly the evacuees to the base in Trenton, Ontario, the country's main military hub for air transport, and hold them in quarantine for two weeks. The outbreak has killed 492 people and sickened nearly 25,000 worldwide.

Canadian Prime Minister Justin Trudeau said on Wednesday the plane was expected to arrive on Friday.
