Ethiopia is experiencing an HIV/AIDS pandemic of shattering dimensions. A total ofrn1,3 19,795 persons were estimated to be living with HIV/AIDS in the year 2005 inrnEthiopia (MOH, 2006) .The HIV/AIDS epidemic had already spread to all thernadmini strative provinces of Ethiopia. However, the prevalence levels were different,rnsuggesting a difference in the times when the epidemic started in the provinces.rnIn Ethiopia, the appl ication of GIS to benefit our society has not been optimized. Thernargument of the present thesis is that recent developments in Geographical InformationrnSystems (GIS) can greatly increase our capacity to undertake the spatial tasks needed tornimprove monitoring and management of the spread of HI VIA IDS.rnGIS a powerful computer based technology; is involved in the storage, analysis,rnretrieval, and visual ization of spatially referenced information for monitoring, planning,rnassessment and management due to the options and capabilities for data maintenance andrnmanipulation through addl deletel change,overlay,query ,proximity, display and datarnretrieval and reporting. Visualization of maps in various combinations and permutationsrnas in itial and final output (ranged color maps or proportional symbol maps to denote thernintensity of a mapped variable) to depict various ART Hospitals and health centers forrngeneral monitoring health infrastructure.rnThe study strongly supports the usefulness of advanced technology like GIS for thernManagement and handling of large database of spatial and aspatial nature in context ofrncommunicable and non-communicable diseases.rnKey words: HIV/AIDS, GIS, ART Health centers and Hospitals, Mapping, Analysi
