When communities are really in control: ethical issues surrounding community mobilisation for dengue prevention in Mexico and Nicaragua
Abstract We discuss two ethical issues raised by Camino Verde , a 2011–2012 cluster-r and omised controlled trial in Mexico and Nicaragua , that reduced  dengue risk though community mobilisation . The issues arise from the approach adopted by the intervention , one called Socialisation of Evidence for Participatory Action . Community volunteer teams informed householders of evidence about dengue , its costs and the life-cycle of Aedes aegypti mosquitoes , while showing them the mosquito larvae in their own water receptacles , without prescribing solutions . Each community responded in an informed manner but on its own terms . The approach involves partnerships with communities , presenting evidence in a way that brings conflicting views and interests to the surface and encourages communities themselves to deal with the result ing tensions . One such tension is that between individual and community rights . This tension can be resolved creatively in concrete day-to-day circumstances provided those seeking to persuade their neighbours to join in efforts to benefit community health do so in an atmosphere of dialogue and with respect for personal autonomy . A second tension arises between research ers ’ responsibilities for ethical conduct of research and community autonomy in the conduct of an intervention . An ethic of respect for individual and community autonomy must infuse community intervention research from its inception , because as research ers succeed in fostering community self-determination their direct influence in ethical matters diminishes .
