The computer-based design process in diagnosing eight water-borne diseases gives input for future developers of system that diagnosis the identified diseases. The study designs an algorithm for eight waterborne diseases that allow the patient to give inputs pertaining to the series of questions to identify what specific disease they are currently experiencing. This designed algorithm is beneficial for future development of intelligent systems related to waterborne diseases. The algorithm on E-Doctor for Waterborne diseases successfully identified the different waterborne diseases based on varied symptoms. This will serve as an alternative for general practitioners in diagnosing patients who have waterborne diseases and for those individual who are health conscious.
