The high rate at which Africans die of syphilis yearly has been majorly attributed to the uneven ratio of the patients to competent medical practitioners who provide Medicare.This mortality rate has always drawn the attention of researchers and different approaches had been used to bring the rate down.This paper provides a software solution that personifies the expertlike way of providing diagnostic service to patients who suffer this disease.It is capable of making approximate diagnosis based on uncertainties.The system has been structured into five components: user interface, fuzzification, knowledge base, inference engine and defuzzification.The user interface uses a graphic user interface based method of human-computer interaction while the fuzzification component has transformed crisp quantities into fuzzy quantities using both interval-valued and S-curve membership functions.The reasoning has been achieved using root sum square (RSS) method and transformation of fuzzy values to scalar ones was through weighted average method.This system was tested and found effective.
