Sir, it's John Ossowski. I'll respond to that.
We have worked out with Public Health a way to make sure that their agents, who are better placed than our officers, are available either by telephone or in person to assess the health of these individuals. It depends on the port of entry and the volumes we're working with. So far we're satisfied that people are getting the right medical advice with respect to the symptoms they are speaking about with the public health officials.
