uruli ulcer (BU) is the third most common mycobacterium disease after tuberculosis and leprosy. The disease eats through
the skin, muscle and bone, leaving victims with disfiguring and debilitating craters. Ghana is the second most endemic
country globally, after Cote d?Ivoire with over 1,048 cases with the most endemic regions being the Ashanti, Greater Accra,
Central and the Brong Ahafo. The paper uses Area to Point Kriging (ATP) method to model the spatial distribution of Buruli
ulcer incidence in the Ashanti and Brong Ahafo Regions of Ghana. The ATP method used consist of three steps; filtering of noise
in the data based on Poisson kriging, the mapping of the corresponding risk at a fine scale and estimating geographical clustering
of the disease at the administrative units. This paper focused on the spatial analysis of Buruli ulcer incidence in the Ashanti and
Brong Ahafo region in terms of sex.
The research revealed that there is large range of spatial autocorrelation in males than in females in the various administrative
units. The administrative units in Brong Ahafo close to Ashanti region have high BU incidence than the units far away from the
Ashanti. The clustering analysis revealed that only Amansie West district is statistically significant for both sexes.
