This talk outlines how mathematical modelling can inform sustainable public health policy when integrated with other disciplines, illustrated through work on Cystic Echinococcosis, a parasitic zoonosis. I present practical examples that bring together transmission models, field epidemiology, veterinary practice, social science and economic assessment to co produce interventions that are feasible, acceptable and maintainable over time. Emphasising a One Health perspective, the session shows how integrated approaches improve surveillance, target control measures, and clarify trade offs and uncertainties for decision makers. Attendees will see how collaborative, people centred modelling generates operational recommendations that are more likely to be adopted and sustained in real world settings.
