Dengue is an increasing public health problem in Nepal, especially in urban areas like Kathmandu. It is a mosquito-borne disease that spreads easily in places where stagnant water and poor waste management create ideal breeding grounds. Effective dengue control requires more than just spraying insecticides but needs an active involvement from communities to design solutions that fit their daily realities. The proposed study aims to explore community perceptions and practices related to dengue risk and vector control and to develop community-led spatial risk maps of potential mosquito breeding sites using participatory GIS (PGIS). By integrating qualitative insights with spatial mapping and entomological assessment through the House Index (HI), the study seeks to identify ward-level dengue risk hotspots and assess concordance between community-perceived and entomologically confirmed breeding sites. The study aims to bridge the gap where community-led participatory geographic information system (PGIS) will be combined with house index (HI). The project positions local residents as mappers who identify, map, and analyze breeding risk areas.
