In this paper we propose the design and implementation of a generic medical knowledge based system (MKBS) for identifying diseases from several symptoms and signs. To diagnosis diseases, user will be asked by the system for different questions and finally inference engine will use certainty factor to prune out low possible solutions. In this system some important aspects like Knowledge bases system, Knowledge representation, Inference Engine has been addressed. New certainty fact has been introduced to get conclusion about same firing rules. The proposed disease diagnosis system also uses a graphical user user interface to facilitate user to interact a with expert system more easily. The proposed system is generic and knowledge based, and it can be integrated with any rule bases system in disease diagnosis.
