The type of research used was an analytic observational study with a cross-sectional design. . This research was conducted in the working area of the Bola Health Center with a sample of 97 families. The data analysis used was univariate and bivariate analysis with the chi square statistical test . The results of this study indicate that there is a relationship between knowledge (p=0.011), attitude (p=0.040), education (p=0.044) and prevention of dengue hemorrhagic fever in the working area of the Bola Health Center. Meanwhile, those that were not related to the prevention of dengue hemorrhagic fever (DHF) in the working area of the Bola Health Center were age (p=0.711), income (p=0.062), occupation (p=0.544).
