Palembang is classified as a city that has tropical climate with abundant rainfall, even in the driest month. These characteristics indicate that the city has a high potential for the occurrence of dengue virus disease. The areas of incidence of dengue virus disease in Palembang can be classified into five areas; South, Center, North, West and East. The aim of this paper is to map the incidence of dengue virus disease into these areas based on significant factors using the quadratic discriminant analysis. The stratified sampling technique is applied to obtain the respondents who have family members suffering from dengue disease. The results showed that the incidence of dengue virus disease in each area is significantly affected by all factors, except the age of patient, hygienic behavior of respondent, age and occupation of family head and number of bedrooms. The results of the Wilk’s lambda test and the F test indicate that gender and blood type of patient; age, education, occupation, income and knowledge of respondent; occupation and income of family head; type of residence; number of bathrooms that have tubs and clean water source are relatively different in each area. The overall correct percentage of the mapping result is 66.7%.
