Onchocerciasis is a tropical parasitic disease prevalent in areas of South America and Africa. The purpose of this study was to estimate the prevalence and concentrations of onchocerciasis cases in Mozambique in order to establish a medical relief effort. GIS was used to determine areas where the exposure to onchocerciasis was believed to be greatest and to relate disease prevalence to environmental factors. This risk exposure model was then used to determine the optimal location from which to base operations as well as to coordinate the airlifting of supplies to various parts of the country.
