On March 5 2026, PREZODE will convene a panel discussion to examine how to define and measure indicators that capture the added-value and impact of zoonotic disease prevention.<\/h2>\n\n\n\n

<\/p>\n\n\n\n

Preventing the emergence of zoonotic diseases is one of the defining challenges of our time \u2014 and one that is inherently cross-sectoral. In a One Health world, prevention requires coordinated action across human health, animal health, and ecosystems, and demands tools and frameworks that can demonstrate its value long before a crisis unfolds.<\/p>\n\n\n\n

The discussion will address the methodological challenges, data gaps, and equity considerations that shape \u2014 and often constrain \u2014 the way we monitor, evaluate, and justify investment in prevention.<\/p>\n\n\n\n

<\/p>\n\n\n\n

This session takes place on the 5th<\/sup> of March – 4:00 and 5:30 pm CET – (3:00-4:30 pm UTC)<\/p>\n\n\n\n

The panel will feature Dr. Osman Ahmed Dar<\/strong>, Senior Advisor at the Africa Centres for Disease Control and Prevention (Africa CDC) and member of the One Health High Level Expert Panel (OHHLEP); Prof. Wanda Markotter<\/strong>, Director of the Centre for Viral Zoonoses at the University of Pretoria and Co-Chair of the OHHLEP; Dr. Marc Leandri<\/strong>, Associate Professor of Economics at Universit\u00e9 Paris Saclay and researcher at UMI SOURCE-IRD, and Yoeri Booijink, <\/strong>One Health Economist at CIRAD. The discussion will be moderated by Dr. Christina Pettan-Brewer<\/strong>, global One Health leader at the University of Washington School of Medicine. (See bios below)<\/em><\/p>\n\n\n\n

The prevention paradox<\/h3>\n\n\n\n

<\/p>\n\n\n\n

Measuring the impact of zoonotic disease prevention faces a fundamental paradox: when prevention succeeds, nothing happens \u2014 no outbreaks, no spillover, no transmission. This invisibility makes it extremely difficult to demonstrate prevention\u2019 added-value, justify investment, or sustain political commitment. Overcoming this requires developing indicators capable of capturing “negative” outcomes \u2014 avoided spillover, reduced transmission risk, improved system resilience \u2014 and identifying which, among process, output, outcome, proxy, and early-warning metrics, are most actionable for policymakers and funders.<\/p>\n\n\n\n

<\/p>\n\n\n\n

A methodology frontier<\/h3>\n\n\n\n

<\/p>\n\n\n\n

A second layer of complexity comes from the cross-sectoral nature of One Health prevention. Conventional indicator sets rarely capture the co-benefits that prevention generates \u2014 such as biodiversity protection, food system safety, or social resilience \u2014 nor do they easily integrate data across human, animal, and environmental health sectors. Translating emergence risk into economic burden remains a key methodological frontier.<\/p>\n\n\n\n

Finally, any indicator framework must be both rigorous and practical: representative across low- and high-resource settings, comparable across scales, and adaptable to local contexts and capacity constraints. Even where good indicators exist, technical, institutional, and political barriers can prevent them from driving action \u2014 and closing that gap will be a core focus of the discussion.<\/p>\n\n\n\n
