The second objective aimed to develop a geospatial database for Johor HFMD cases. The last, which is the third objective, was to analyze the prevalence of HFMD in Johor via geospatial density and distribution techniques using open source software. This study is significant in order to provide the information of HFMD prevalence to the Department of Health Johor. The result indicates that the disease can occur throughout the year, however it reaches peak in February and March, of which is during the dry season. Concurrently, the distribution of HFMD cases in Johor exhibited a clustered pattern., which most mean centres and standard deviation ellipses occurred at similar areas. The direction of the standard deviation ellipses also oriented towards the northwest of Johor.
