Murphy's policy argument is to extend the discovery-tocontrol continuum to the full range of zoonotic diseases. The discovery-to-control structure draws on elements from fundamental scientific research, to the creation of an effective practitioner community, to creating and sharing data bases drawn from increased national and sub-national surveillance, to the full range of actions required in the final control stages of zoonotic diseases. And at each step, he is sensitive to their costs (without necessarily employing the various languages of public policy that apply). He recognizes the extensive nature of the final phases of the project.
