Every country is different, and my opinion also differs with each country, based on my title, my position, my own role and that of the deputy minister. In the United States, there is a division between the Public Health Service, with the Surgeon General, and the CDC and the Health and Human Services.
What we have done is to align. For example, in the infectious disease world, our units parallel the American units, so it makes interaction between us very simple. So the head of that division can talk to their American counterpart, as opposed to two or three different people.
We did look around the world a bit. We continue to evolve, but every country is different.
