A chariot, Nidhi Rath, is the star attraction of the campaign.
BMC mayor K Madhavi flagged off the chariot in the presence of corporation officials yesterday.
Though no dengue cases have been reported in the town so far this year, waterlogging in the low-lying areas have been a cause of concern.
BMC officials stressed the need to clean drains and waterlogged areas to destroy mosquito larvae. Besides launching the awareness programme, the civic body also sprayed insecticides at certain areas, said a corporation health official.
The main reason for spread of dengue, chikungunya, malaria and Japanese Encephalitis is stagnation of water, which helps the spread of infection, said a medical officer of the social medicine department, MKCG Medical College and Hospital here.
