The DHF prevention efforts have been continually conducted by the local health office, but some technical obstacles such as surveillance system is still very weak, and this is known as an important part in decision making process to handle the problem using evidence based information. The research objective is to obtain information on dengue endemic mapping through GIS (Geographic Information Systems) to strengthen district surveillance system in district level. Most DHF cases occur in the productive age and located in urban areas with the larva-free rate is low. The direction of movement of the case are local diffusion. Karawang district is a low-lying areas prone to flooding. The rainy season occurs in late October to early May, but the rise of dengue cases at the turn of the rainy season to dry season, this indicates that the humidity in Karawang district supports the mosquito vector breeding. Foging will only kill adult mosquitoes, dengue control programs need to involve community participation and emphasized on public areas like schools and offices because a lot of dengue cases occurred in the productive age. GIS is capable of producing a map factors of risk and map of the case to allow for planning and evaluation of area-based dengue eradication program. GIS is useful in surveillance environmentally based disease, health interventions, and disease prevention strategies.
