Just to reinforce what I said, at the moment we don't screen for these conditions at all, so nobody gets screened. I don't propose that would change. At the moment, the inadmissibility on health grounds is about 0.3%. So at the moment we don't screen and we don't have people coming here. Right now, the people abroad could be saying, I know I've got hepatitis B—no question of faking results—I know I've got it, and I could go to Canada and get treated. But, actually, that's not happening.
I don't propose that it gets added to the screening outside the country at all. The screening that happens inside the country, the way I would frame it, is that everybody here's supposed to have an annual health check, and this is just an annual health check that happens when people arrive. When you do an annual health check, you can be screened for hepatitis B. One of the reasons for screening is that if you haven't been immunized in the past, you could be screened to make sure that you need immunizing.
I don't want this to get out of proportion because it's really feasible, and I don't think it's going to present a huge burden.
