Statistical Analysis Of Spatial Distribution Of Malaria In West Shoa Zone Ethiopia

Malaria is a major cause of illness and death in large parts of the developing world,rnespecially in Africa. Accurate estimates of malaria distribution are required for planning,rnimplementation and evaluation of malaria control programs. The main objective of thisrnstudy is to examine spatial patterns of malaria distribution in West Shoa zone, OromiarnRegion, Ethiopia. Malaria incidence data for 2009 from all health centers of the zone,rnpopulation size and meteorological data were used. The statistical methods used includernglobal and local measures of spatial autocorrelation as well as spatial autoregressivernmodel. The results of this study indicate that malaria incidence varies according torngeographical location, with eco-climatic condition and showing significant positivernspatial autocorrelation. Significant local clustering of malaria incidence occurs betweenrnpairs of neighboring districts (known as Woredas). Malaria incidence was higher in thernwestern part of the zone and lower in the eastern part of the zone. The results of spatialrnlag model indicate a significant relationship between malaria incidence andrnmeteorological variables (mid-land zone, hot zone, rainfall, minimum temperature andrnmaximum temperature)
