We were not proposing that no pre-screening happens at all. Assuming that these people are screened to the extent that they are healthy individuals when they arrive here, they can still be healthy, for all intents and purposes, but some of them, and it's going to be a minority, may carry hepatitis B or hepatitis C viruses by virtue of the fact they come from countries of the world—East Asia and Southeast Asia being very prevalent places for hepatitis B, and other parts of the world having more hepatitis C than is found in Canada. Now, that's not going to be most people, it's going to be a few, but it's a higher rate than is found in Canada.
So it is worth screening them just for those few viruses, and then you can treat them. But it's not going to be a huge burden, I will put it that way.
