ABSTRACT
In 2003, International Development Research Centre (IDRC) funded a project examining the effectiveness of an Ecohealth intervention for managing the transmission of Chagas disease to humans via the Triatoma dimidiata. IDRC consequently funded a second study in 2011 to assess the degree to which the Ecohealth intervention could be scaled up to other communities in Latin America and the Caribbean. The 2004 environmental project demonstrated the effectiveness of the Ecohealth approach in preventing the transmission of Chagas disease. The Chagas case also demonstrates that, in the context of scaling, Coordination involves more than the participation of stakeholders. The success of the Ecohealth intervention rested on a participatory multi-stakeholder approach, as well as community buy-in. Scaling came with a more diverse set of communities, marked by variation in the initial level of interest and readiness to participate.
