Public health officials say risk of contagion is low as Canada reports 4th case of coronavirus

Public health officials in Canada confirmed another person tested positive for coronavirus on Friday as countries around the globe worked to contain the spread of the disease.

That brings the total number of confirmed cases in the country to four — three in Ontario and one in B.C.

The most recent case is a woman in her 20s who attends university in London, Ont. She tested positive for the virus after returning from a trip to Wuhan, China, on Jan. 23, Ontario public health officials said on Friday.
