Maximising Impact, Optimising Investment: Cost-effective strategies for Leishmaniasis Prevention

As climate change continues to expand the habitats for sand fly vectors, leishmaniasis is no longer confined to traditionally endemic areas, posing a growing public health across Europe. To assist decision-makers in navigating this challenge, the CLIMOS project conducted a Cost-Effectiveness Analysis (CEA) across 18 European and associated countries, evaluating major preventive interventions. The core findings of this analysis outline a clear pathway toward strategic resource allocation including campaigns, targeted strategies, vector control measures and preparedness costs. To transform these economic insights into practical governance, the CLIMOS partners recommends that health authorities and policymakers prioritise actions such as mandatory reporting, One Health surveillance and preventive tools among others.
