This study investigated the geospatial analysis of cholera in Kano Metropolis, Kano State Nigeria, from 2010-2019. Health Facility Based records of cholera cases were obtained from Kano State Ministry of Health (KSMoH) which includes the years of cholera outbreak, number of people affected, their age and sex, locations and the state of their health after being treated. These were analyzed using both descriptive and inferential statistics. Arc GIS was used to map out areas with cholera cases. Choropleth maps were generated showing yearly rates of occurrence for each ward. The results show that cholera is endemic and it occur yearly in the study area in both the wet and dry season, though with more cases in the wet season. Highest number of cases was recorded in 2013 and 2014 (21% and 43%) and other years of the study period having low and moderate cases respectively. For the study period, cholera cases were recorded in the entire Local Government Area with Dala and Kano Municipal having the highest number of cases (16% and 15% respectively) while Tarauni has the least number of cases (5% of the total cases). The result also revealed that male cases slightly outnumbered that of females, which is 54% against 46 while children between the age group of 0-14 were more affected than any other age group, accounting for about 30% of the total cases recorded. The result of this study is important for public health interventions, especially among the vulnerable age groups such as children.
