We do our absolute best to try to know what's going on. There is a worldwide network of people who are examining data every single day. The World Health Organization picks up information from all around the world and relays it to the Public Health Agency of Canada, and there is a cascade system within Canada that goes through the provincial and territorial governments and into agencies such as the one I work in, and we work very closely to keep a constant watch for new emerging issues around the world.
The international regulations, which you may or may not be aware of, require every country to report to the World Health Organization anything of public health significance and to do that immediately, and there's a set of criteria. There are some specific diseases that are reportable, but there is also, I think most importantly, a generic one that says anything that is regarded as being unusual and of public health significance must be reported immediately. That's important, because of course with SARS we didn't know what it was until it was here.
The World Health Organization, recognizing the impact that SARS had, knew it had to change its regulations. So Canada has signed up to that and participates in that and we benefit from it. That's a very well-rehearsed system.
