Yes, we work with quite a range of countries, some closer than others. We're a key part of the global health security initiative, and the Global Health Security Action Group, as one of the G-7-plus one countries, in terms of planning for a whole range of not just outbreaks and epidemics, but also bioterrorism and other things.
We work very closely with CDC. There are some things they're better at than we are, which we learn from; and there are some things we're better at than they are, which they learn from.
And we share capacity. For example, PulseNet, which looks at characterizing the genetic makeup of bacterial diseases that cause food poisoning, for instance, is a shared system. We and the Americans and the Mexicans now use that. It makes it easier for us to figure out: oh, these five cases in Toronto, these three cases in New York, and these 12 cases in Atlanta are all the same strain, coming from the same place. What are the common factors? Then we can trace those back to figure out where it came from. The listeria outbreak is a good example of that.
