Whose knowledge matters? Trypanosomiasis policy making in Zambia

Zoonotic diseases – pathogens transmitted from animals to people – offer particularly challenging problems for global health institutions and actors, given the complex social-ecological dynamics at play. New forms of risk caused by unprecedented global connectivity and rapid social and environmental change demand new approaches. ‘One Health’ highlights the need for collaboration across sectors and disciplines to tackle zoonotic diseases. However, there has been little exploration of how social, political and economic contexts influence efforts to ‘do’ One Health.
