In recent years, fuzzy set theory and Fuzzy Logic are applied successfuly in medical expert systems as CADIAG, MILORD etc. This paper intends to provide a short survey on application of fuzzy set theory in medicine, especialy, fuzzy logic in medical expert systems. An improved fuzzy inference model of CADIAG-2 for medical diagnosis combining negative and positive evidence is presented. This model can be used for obtain more smooth transition between confirmed and disconfirmed diagnoses.
