Formal approaches have recently been developed to monitor and respond to EIDs by examining their properties with respect to transmissibility and potential for causing significant disease in transfusion recipients. New tools for quantitative risk assessment are under development to facilitate rigorous evaluation of scientific evidence, while also formally soliciting and considering public perception and fear and health economic realities.</p> </sec> <sec id="voxs12082-sec-0005" sec-type="section"> <title>Conclusion</title> <p>These ongoing efforts at refining our risk surveillance, assessment and decision analysis tools, coupled with focused research to quantify risks and evaluate interventions, presage an era of sustained safety and enhanced public trust in the blood supply.</p> </sec> </abstract>
