Summary
# Editorial Summary: Epizootic Lymphangitis Control in Ethiopian Cart Mules Between 2010 and 2017, researchers working with The Donkey Sanctuary implemented a participatory, community-based intervention targeting epizootic lymphangitis (EZL) in cart mules in Bahir Dar, Ethiopia, combining muleteer education, improved harness design, wound management, veterinary training, early treatment protocols, and regulatory reform across transport and animal health authorities. Annual EZL prevalence fell dramatically from 23.9% to 5.9%, whilst wound prevalence decreased from 44.3% to 22.2%, despite the mule population expanding threefold from 430 to approximately 1,500 animals over the study period. Success hinged on shifting from top-down NGO-driven approaches to building genuine community ownership through participatory learning tools, strengthening veterinary service capacity, establishing muleteer competence in prevention strategies, and fostering trust between stakeholders—particularly between muleteers and veterinary professionals. For equine practitioners and advisors working in endemic regions, this work demonstrates that sustainable disease control requires embedded systemic change: robust local bylaws, viable economic mechanisms for humane euthanasia of advanced cases, improved infrastructure standards, and genuine collaborative relationships alongside clinical and educational interventions. The findings align with OIE welfare standards and provide a replicable framework for addressing infectious disease in working equid populations where community buy-in and local service strengthening are as critical as the clinical tools themselves.

Practical Takeaways
- •EZL control requires multi-faceted approach: improve harnesses and work practices, educate handlers on wound prevention, strengthen veterinary service access, and establish clear euthanasia protocols for advanced cases
- •Build trust and ownership with local users—working with muleteers rather than imposing solutions led to sustained behaviour change and disease reduction
- •Working equid welfare improvements (reduced wound prevalence) directly support disease control; investing in harness design and traffic management protects both animal welfare and herd health
Key Findings
- •Annual EZL prevalence reduced from 23.9% (2010) to 5.9% (2017) through integrated community-based intervention
- •Wound prevalence decreased from 44.3% (2011) to 22.2% (2017) despite mule population increasing 3.5-fold
- •Community ownership, stakeholder engagement, and strengthened service provision systems were essential for sustainable disease control
- •Multi-component interventions (education, harness improvement, treatment protocols, traffic guidelines) were more effective than single approaches
