One Health Study Design

One health is an integrated approach that considers human, animal, and environmental health components that can improve prediction. One health implies that data on man and animal health and environmental indicators are studied and interpreted together. This chapter focuses on population-based quantitative and qualitative one health study designs with an emphasis on field surveys to understand disease dynamics and how to control measures being tested. The aim is not on early diagnoses of emerging diseases but instead of that on endemic zoonosis. It first describes examples on joint monitoring and surveillance to control diseases and then practical information on planning of a field study design, and concludes on the advantages of one health study designs. Also discussed are possible constraints for their implementation. For the examples, single sector approach could not explain the main epidemiological considerations.
