Abstract: | This paper examines the spatial variation of HIV/AIDS prevalence rates in Nigeria. It uses Exploratory Spatial Data Analytical (ESDA) techniques to provide insight into the pattern. The overriding objective is to determine if there is a significant spatial clustering of HIV/AIDS. The calculated and mapped Global and Local Moran’s I, and Getis and Ord G i * values reveal certain states such as Benue, Nassarawa, Federal Capital Territory (FCT) and Cross River have significant spatial clusters of HIV/AIDS rates in Nigeria. The spatial analysis enables policy makers to identify states most affected, and design effective and culturally acceptable preventive measures. Specific policies targeted at states are a more appropriate approach in tackling the epidemic rather than the usual universal cookie-cut HIV reduction strategies that may not be applicable to the different cultural milieu. |
