I think, in a way, there's a very different culture associated with the health sciences and with the veterinary and livestock communities. They're living in very different professional organizations, and they're living in different institutions. Clearly, trying to merge the programs and the expertise and the knowledge from both the animal side and from the human health side makes for a much more effective strategy in detecting these emerging disease problems -- how to respond to them very effectively and how to try to start predicting where these emerging diseases are going to come from, which areas of the world, which types of communities, and so forth. Working closely with the public health officials, veterinary authorities, agricultural people, wildlife specialists -- pulling in all those kinds of institutions and different expertise -- makes you much much more effective in dealing with emerging disease problems.
