The study population was all 80 students in grades III–VI, with a sample of 67 respondents selected using a purposive sampling technique. Data collection was carried out using a questionnaire regarding the level of knowledge of dengue fever prevention, then analyzed using univariate analysis to determine the frequency distribution and percentage. Results: The results showed that most of the respondents were aged 12 years (32 students (47.8%) and the majority were female (43 students (64.2%). The level of student knowledge regarding dengue fever prevention was dominated by the sufficient category with 44 respondents (65.7%), followed by the good category with 18 respondents (26.9%), and the poor category with 5 respondents (7.5%).
