Geospatial Analysis, Mapping, and Clustering of Cholera Resurgence in Malawi

Abstract

Abstract Background The resurgence of the cholera epidemic in Malawi poses a substantive threat to the government schema and necessitates more targeted intervention methods for long-term management. This study focused on geographical analysis of cholera incidence in Malawi to investigate the existence of regional hotspots and predictors. Methods The geographical association between cholera occurrences and environmental risk variables in the research region was mapped and explored in this study. The research area was divided into three regions thus northern, central, and southern. ArcGIS 10.41 was also used to gather and analyze GIS layers such as cholera incidence data from government archives. Results The study found that hotspots were found to be mostly in towns, near water bodies, and garbage dump sites. According to the findings of this study, garbage disposal sites and markets were the most predisposing factors, whereas abattoirs were the least. Conclusion The study's distinctiveness stems from the use of mapping to show the hotspots and the pattern of cholera risk, as well as to offer unambiguous information for the creation of environmental supervision methods.
