An abnormal increase in the incidence of dengue was reported at Vellore Corporation since September 2012. Intensive control operations supported with health education campaigns were carried out from September to November 2012 till the outbreak situation subsided. During December 2012, a cross sectional survey was conducted at Vellore Corporation to assess the impact of the health education campaigns on the knowledge, attitude and practice in the community and also to assess future needs. A total of 101 families from four different locations at Vellore corporation were interviewed on pre-structured formats. Though 80% of the respondents felt that dengue could be effectively prevented and controlled only with community participation, majority of them lacked awareness on the day time biting behaviour of Aedes mosquitos, their indoor resting and breeding habits and relevance of specific control measures focused on the bionomics of dengue vectors.
