2 Laboratory Containment of Wild Poliovirus in the United States Phase I National Survey and Inventory Final Report January 15, 2004

3 The Purpose of Laboratory Containment To minimize the risk of reintroducing wild polioviruses into the community after eradication 2nd edition 2003

4 Purpose of Phase I To encourage labs to dispose of unneeded wild poliovirus materials Establish National Inventories of laboratories retaining such materials.

5 US Survey and Inventory Began in October 2001 NVPO through contract with the Task Force for Child Survival and Development Working in partnership with CDC

6 Steps in the survey process Develop the Action Plan Authorize the survey (WHO, HHS, OMB) Enlist support of laboratory community Perform pilot surveys (x2) Establish database of institutions/labs Develop survey instruments Implement the survey

7 Database: Categories of Institutions CLIA Certified Non-Complex Testing Most likely to possess (1,216) Least likely to possess (26,844) CLIA Certified Complex Testing May possess (4,369) Academic Federal Government Industry State and Local Government Hospitals Private Labs

10 Finding no WPV materials among 24,206 responders confirmed small clinical labs were unlikely risks. Follow-up of “least likely” labs discontinued per NVAC workgroup.

12 Post-survey literature search To confirm that all institutions/laboratories publishing on wild poliovirus materials are on the National Inventory To identify laboratories publishing on infectious agents that share common enteric origins or replicate on poliovirus-permissive systems.

13 Selected PubMed Literature Search 2002 & 2003 Bacterial and Viral n = 1906

15 Institutions publishing (1993-2003) on any poliovirus and not listed on survey database 1 community college, environmental project now discontinued 1 biotech startup, now defunct

16 Institutions publishing (1993-2003) on associated viruses and not listed on survey database 1 water service Co. R&D lab 2 non-profit foundation laboratories 1 community college 2 biotech startups, 1 now defunct

17 Summary ( Phase I) The US national survey of >32,000 institutions and >105,000 labs is complete. The quality and completeness of the survey is validated by a10 year literature search The National Inventory consists of 122 institutions with180 labs. Recommendations for Phase II are made and responsibilities defined in the Report
