In India, Mosquito borne diseases constitute a major public health problem in the list of communicable diseases. The most important are malaria, dengue fever, chikungunya fever. Some environmental factors greatly influence the vector prevalence. One of the important components of vector-borne disease control programme is to impart awareness about mosquito bite prevention in the general community. Therefore, the urgent need a technology to give awareness to public about present situation of mosquito-borne disease epidemic prevalence in the country. Geographic information system (GIS) is a powerful tool to analyse the distribution of mosquitoes and their relationship to different environmental factors, and can substantially improve our ability to quantify the impacts of demographic, climatic and ecological changes in vector distribution. The influence factor of vector prevalence was collected from particular departments and direct inspection of field survey. The collected data was interpreted using ArcGIS (version 10.0) for thematic map preparation. Result of the study obtained the environmental factors such as human population, percentage of education greatly influence the mosquito breeding sites. The output is laymen friendly model and reaches the public with more interest. This study also stresses the importance of mosquito control measures.
