In Canada we've had three cases. They're all connected to travel to Wuhan. In the other countries, the vast majority are connected to Wuhan. Maybe one of the cases is connected to another area in China.
Currently in two countries that are looking at their cases, Japan and Germany, there has been a very specific case of someone who has not travelled but has contracted the virus from people from Wuhan. In those countries, this suggests that even though they did not travel, they were in direct contact with someone who did come from China.
Those instances are rare and very limited. For sure, in the general population in Canada, the risk is low.
