Although globally, number of malaria cases fell recently, malaria deaths in Sub-Saharan Africa continue to increase. Malaria epidemic is a major public health issue in Ghana. It is first on the top ten outpatient department (OPD) cases each year. Undoubtedly it is critical to know whether the outbreaks are different locally or synchronized across larger regions. This study examined the varying spatial and seasonal distribution in malaria prevalence in Ghana from 1996 to 2014. We used trajectory and time series analyses for temporal distribution and conducted GIS-based analyses of the spatial distribution of yearly malaria incidence for the 18 years wave of data sets. The study observed that the national annual malaria incidence has increased with varying differences in risk across the country. The study findings show that public health resource allocations and education should concentrate on endemic areas with the highest malaria risk in Ghana.
