Dengue fever is an infectious tropical disease caused by the dengue virus. Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti. The Study area of Madurai is located at 90 30’ and 100 30’ longitudes and between 770 00’and 780 30’ latitude. The purpose of selection of the study area is to investigate the spatial distribution of Dengue at the micro level in an urban area of Madurai city and to analyze the causal relationships between the distribution of Dengue and its association with socio – economic, environmental, behavioral and medical variables.The data collected were taken by using the method of stratified Random sampling and a total of 300 samples were collected from the study area with reference to different age groups and sex ratio. It includes mapping of the disease using the Arc GIS. The data were analyzed with the help of Multivariate statistical technique known as ‘Factor Analysis’ The study has identified that environment parameters played a major role in the health status of Dengue.
