Surveillance Stakes are high Curves ahead Map??? Road ends Information for action Traffic delays Run out of gas Safeguarding Animal Health
Animal Health Safeguarding Review 2001 Primary Recommendation: Congress and the USDA must provide funding and act to rebuild the state and national infrastructure for animal disease control, emergency disease preparedness and response.
Principle 1a – A comprehensive, coordinated, integrated surveillance system is the foundation for animal health, public health, food safety, and environmental health
Value of Surveillance • Early detection– reduce spread • “Proof” of freedom • Food safety/security • Public health Market Access Safeguarding Animal Health
Role Definition • National surveillance • SAHO / Tribal Authorities • Producer • Private Veterinarian / National Veterinary Accreditation Program Safeguarding Animal Health
Return on Investment • Estimate $565,000,000 per hour cost of FMD outbreak Safeguarding Animal Health
Return on Investment endemic diseases • 10% reduction in morbidity/mortality • ~$ 1,400,000,000 Safeguarding Animal Health
National Surveillance Exchange of information between health authorities is needed for safe flow of commerce and for disease control decisions. Ongoing publication of statistical data on diseases and populations Prompt notification of unusual or emergency situations Public Policy Transparency in methods used for analysis Access to complete and correct information Challenging assumptions Safeguarding Animal Health
The stakes:2009 meat/poultry exports But that’s only part of the story…. • $11,7 00,000,000 • > $25,000,000,000 to economy • ~150,000 jobs Safeguarding Animal Health
Greater Demands on National Animal Health Surveillance System food safety Agro-terrorism Emerging diseases food security National economy Public health Safeguarding Animal Health
Road hazards: Information sharing? Confidentiality? Safeguarding Animal Health

Comprehensive Integrated NAHSS • Cost efficient • Benefit to broad stakeholder base • Disease flexible • Rapidly responsive And gives Information for National Status Safeguarding Animal Health
Weighted Benefit/Cost for surveillance P (intro) * SSe* p(success) * costs averted ______________________________ Cost of surveillance Safeguarding Animal Health
So far… • Stakes are high • We know surveillance concepts • We know the budget is limited • We’ve learned how to value/prioritize Let’s talk about approaches to surveillance Safeguarding Animal Health
Disease Specific Surveillance • Random sample • Targeted toward higher risk • Inference possible with RR • Definition of subpopulation • Concepts of compartmentalization, zoning, regionalization – risk based recognition Safeguarding Animal Health

Remember our cost benefit formula? • P(intro) high • SSE also high • Mitigation potential yes, it’s realtime • Cost averted many diseases, very high • Cost of surveillance relatively low Safeguarding Animal Health
Creative Thinking • Cooperation and participation • Confidentiality and data sharing • Information management systems • National coordination of procedures for reporting and action • Government verification role • Epidemiologic investigations • TAIO Safeguarding Animal Health
