To estimate the risk of dengue haemorrhagic fever (DHF) transmission, the larval indices were executed and the regression model was fitted to explain and predict the relationship between household’s activities and DHF patients. Stratified random sampling was used to select the sample, 11 villages of Kreang sub-district were assigned to stratum. Three hundred household were assigned to sample units. Descriptive statistics were used to analyze the data and stepwise regression was used to form the model. The results showed that 9 out of 11 villages were high DHF risk transmission while 2 villages were medium risk. 26.9% of the variation of DHF patients was explained by number of water storage container, Aedes aegypti in drainage of refrigerators, pH and temperature of water in containers, namely X’s. This model. DHF patients = 0.167(X1)+0.120(X3)+0.362(X5)=0.116(X8)+0.128(X13)+0.195(X14) was sufficient to promote the appropriate DHF prevention and control campaigns in this area and nearby localities.
