OTTAWA—Canada’s top public-health official Dr. Theresa Tam says Canada has begun to look at tracking local spread of the novel coronavirus, just as the United States confirmed a case of the virus that does not appear linked with international travel.
The risk of contracting the disease in Canada is low, but for the second day in a row Thursday the number of new cases confirmed outside China was greater than the number of new cases within the country where the illness was first detected.
