This paper explores the potential of Augmented Reality (AR) as an engaging educational tool to enhance the awareness of dengue fever among primary school children in Kuala Lumpur. Motivated by the alarming rise in dengue cases in the region, the study emphasizes the importance of beginning awareness efforts with young children. An AR-based educational tool was proposed due to its interactive and appealing nature, which is particularly effective for young learners. A quantitative methodology was employed, dividing the study into two sections: an entry survey and an exit survey. The entry survey assessed the children's initial awareness of AR technology and dengue fever. The study involved eighty primary school children aged seven to twelve, who were introduced to an AR-based activity book designed to be a visually engaging instructional resource about dengue fever. The exit survey evaluated improvements in the children's awareness of both AR technology and dengue fever after using the AR-based activity book. The findings indicate a significant improvement in awareness of both AR and dengue fever among the children, demonstrating AR's effectiveness as an educational tool for primary school students. This study highlights the potential of AR technology to enhance public health education and proposes a viable method for future dengue awareness initiatives.
