Socio-Economic Analysis of Impact of Water Projects on Schistosomiasis; Preliminary Report
Describes the progress made on socioeconomic study to analyze and control the incidence of schistosomiasis, a parasitic disease transmitted by snails. The project seeks to help decision makers safeguard against the increased danger of schistosomiasis caused by large-scale water projects. In this report, a previously developed transmission model is refined, using data from the WHO/Tanzania schistosomiasis pilot control project. Modifications include refining the incidence rate equation to include egg counts and human water contact, and designing a mechanism to account for population movement. The study provides numerous figures and tables, information on data processing methods, calculation procedures for the terms in the model, criteria for choosing terms, and a suggested statistical system for schistosomiasis control projects.
