(1) Is it possible to eliminate schistosomiasis as a public health problem on Unguja in three years and to interrupt transmission in five years? (2) Is it possible to control schistosomiasis throughout Pemba (prevalence <10%) in three years and to eliminate it as a public health problem in five years? (3) What are the costs, successful strategies, barriers, etc. associated with three different interventions (MDA, vector control, and behavior change)?
