Geospatial Mapping of Common Waterborne Diseases: An Example from Kwara State, Nigeria

Abstract

Spatial pattern of diseases is of importance to geographers; it assists in determining the origin of diseases and by extension aid our understanding of their consequences for the social system.   One of the methods of determining such spatial pattern is GIS, which combine maps with words, numbers or images to produce maps. Generally, GIS is of importance, because it is a means of obtaining and analysing data from isolated areas still lack road signs. It can also be used to analyze, determine the location of features and relationships to other features; additionally, GIS is also useful to answer where the most and/or least of some feature exists. It is equally useful in determining the density of features in a given space and what is happening nearby some features or phenomenon. Most importantly, GIS assists how a specific area has changed over time (and in what way). The study area is Kwara State, Nigeria and in focus are common waterborne diseases. The data obtained on waterborne diseases were juxtaposed on satellite map of the study area obtained through GIS ArcGIS software. A final map was generated which identified potential areas of common waterborne diseases areas. The study therefore recommends that, application of GIS into spatial analysis of the existing health delivery system.
