Let me focus my question.
Is it true that, in Canada, people in whom the virus has been detected are those who have been in direct contact with China, the site of the epidemic?
In other words, is it true that no Canadian who has not set foot in China has been infected? Are we rather talking about people who were infected over there and who sometimes return with no symptoms when they declare their health status? If so, is that also the case in other countries?
