You raise a very good point. We don't have a good system in this country. We have a lot of very good provincial systems that don't talk to each other, which doesn't do us a whole heck of a lot of good as a country.
If you look at something like influenza, nobody knows how big a problem it is in this country. We all tend to say, “It's just the flu." It's not just the flu; it's the number one killer among infectious diseases in developed countries, and we simply don't have the information.
There was a central study done by a very good scientist in this country, Mohamed Karmali, that suggests that the rate of most diseases is about 25 times higher than reported. That study was done in the Hamilton area, and there's no reason that it would be any different anywhere else. You raise a great point, and I would argue that when you try to tie that to immunization records and that type of thing, you confound the problem.
