The traveller arrived in Montreal from Iran. The information we have is that she arrived on February 14.
Around that time, we had no prior indication of what was going on in Iran, and we weren't paying any special attention, other than what we had in our primary inspection kiosk questioning for Hubei province.
We did go back and look at the situation of when she came through and the type of contact she had with our officers before she then moved on for her flight onward to Vancouver. It was a very brief interaction she had, as it is with many travellers who come through Canada.
She wasn't asked specifically if she had been to Hubei, obviously. She wasn't observed as having any outward illness of any sort at that time, and she progressed through the border clearance processes, as many travellers would on a daily basis. There was nothing abnormal about her when she arrived. Then she became symptomatic, I believe. I'm not sure whether she was symptomatic at the time she crossed or whether she became symptomatic later.
Just as a follow-up, when we did receive information regarding this particular traveller, we went back into our systems to see exactly when she arrived and how she was processed through the airport. We contacted our officers who encountered her to just advise them that they had been in brief contact with the person and to advise them to take appropriate precautions, to call a local health authority if they started to notice any change in their physical condition.
