Background: Most school communities lack awareness and health education toward dengue and its transmission. Aim: To assess the impact of implemented school-based health education intervention program on cognitive and affective domain as well as behavior of high school children as a change agent in the prevention and control of dengue fever in an urban area. Methods: All the children were self-administered a pretested semi-structured questionnaire to assess the baseline knowledge and attitude on dengue fever and its prevention in an epidemic. Multimodal health education intervention was provided and after 1 week, the same questionnaire was used to assess the postintervention level of knowledge and attitude. The Chi-square test and ordinal logistic regression were performed in R. v. 3.5.2. Sample of students was administered observation checklist to document the practices. Results: Majority belonged to the Class X 379 (60.64%) and their level of knowledge during pretest was higher compared to Class VIII and IX. Posttest, level of education of father's (P = 0.006), student's (P = 0.000), and occupation of mother's (P = 0.048) significantly associated with knowledge of students. While mother's education significantly associated with both knowledge (P = 0.000) and (P < 0.036) attitude of the students toward dengue fever. Knowledge and attitude of the students toward dengue significantly improved posttest. There was significant change in behavior practices as evident by reduction of breeding sites after intervention. Conclusion: The cognitive and affective domain of the high school students toward dengue fever improved after the health education program along with behavioral change which highlights the role of students as change agents.
