The book provides researchers, students, and practitioners in public health, anthropology, and related fields with a brief introduction to a health-care model, Community Participatory Involvement (CPI), which for 20 years has proved successful in fighting global health problems. CPI differs from other community-based models in that it involves a unique synergy of local, civil, and political authorities. Using a South American cholera epidemic as an example, the book -explains in step-by-step detail how the CPI model is used; -includes teaching activities, a list of important tools, and model workshops; -demonstrates how the CPI model can be replicated to deal with a diverse range of public concerns, from the control of infectious diseases to animal husbandry to teacher education.
