‘One Health’ Research Ethics in Emergency, Disaster and Zoonotic Disease Outbreaks: A Case Study from Ethiopia

‘One Health’ is the concept that human health and well-being are linked to the health of animals and the environment. The goals of One Health include addressing potential or existing global and transnational health risks, which require policies that are systematic, coordinated, collaborative, multidisciplinary and cross-sectoral. One Health is particularly well-suited for zoonotic diseasesand emerging and re-emerging infectious diseases (EIDs). Epidemics, emergenciesand disasters raise many ethical issues for all involved, including communities, responders, public healthspecialists and policymakers. Our case study describes ethical dilemmas encountered during an animaldisease outbreak investigation in the Somali region of Ethiopia during the 2019 Coronavirus Disease (COVID-19) pandemic with concurrent drought and human conflicts. Outbreak investigations were conducted through systematic collection, analysis and evaluation of pertinent data, and results disseminated to relevant stakeholders. Our observations highlighted the importance of addressing community humanitarian needs and potential risks to responders, including researchers, when responding to animaldisease outbreaks without compromising ethical principles. Community engagement was crucial in resolving technical and ethical issues. Policy gaps related to ethical issues during animalhealth emergencies were observed. Our case study supports the formulation of guidelines and policies for One Health research ethics in Africa and elsewhere to strengthen capacityand ethical decision-making.
