These were analyzed using both descriptive and inferential statistics. Arc GIS was used to map out areas with cholera cases. Choropleth maps were generated showing yearly rates of occurrence for each ward. The results show that cholera is endemic and it occur yearly in the study area in both the wet and dry season, though with more cases in the wet season.
