Abstract: Background & Objectives: Dengue is fast emerging pandemic-prone viral disease in many parts of the world. The incidence of dengue has increased 30-fold over the last 50 years and putting almost half of the world’s population at risk. This study was aimed to evaluate intensity of vectors breeding and risk factors in schools at Dindigul Health Union district. Methods: Schools in Dindigul HUD were inspected and carried out anti larval activities which were performed by Health Inspectors by identifying immature stages of Aedes species in common mosquito breeding habitats in school campus. The Dengue incidence data was collected from the fever surveillance agencies of Government medical colleges and private hospitals.Results: Cement cisterns, plastic drums and tiers were the major breeding habitats and Container Index was >50% recorded in all schools at Dindigul HUD. High dengue incidence reported among school students in the blocks of Bathalagundu, Reddiarchatram and Natham during 2013 than 2012. More cases reported between the months of September and December. Minimum dengue vector infestation recorded in Dindigul municipality and maximum infestation recorded at Reddiarchatram block. Interpretation & Conclusions: The schools are the hot spot for transmission of dengue virus in the community. Hence top priority should be given to schools during planning of Dengue control activities to curtail the dengue prevalence and risk factors among the student community.
