The official machinery has been geared up to prevent outbreak of vector-borne disease, if any, owing to the onset of north-east monsoon in this district.

According to the Deputy Director for Health Services M. Madusoodhanan, three zonal level teams equipped with vehicle, vector control equipments, insecticides and manpower have been set up at Nagercoil, Padmanabhapuram and Kuzuthurai to access vector density, carry out source reduction and fogging operations. Periodical assessment of vector density in select sites would be carried out by the zonal entomological team in Tirunelveli.

A computerised reporting system has been functioning at the office of Deputy Director of Health Services to receive health related information from the public, laboratories, private and government hospitals. These reports would be analysed at the district unit and early warning signal would be picked up to forecast outbreak of disease and the information would be passed on to the local health authority to initiate immediate preventive measures.

Reports would also be received from the sentinel centres, ICDS centres, volunteers, elected representatives, government departments etc. All cases would be traced in the field through the public health network for immediate action. Special door-to-door surveillance would be organised on all Saturdays in disease endemic pockets for early detection.

As a long term measure, indoor residual insecticidal sprays would be carried out in malaria endemic villages, based on disease indices during peak transmission season, i.e., from June to December. Mosquito breeding sources would be enumerated and based on the situation a chemical treatment with abate or introduction of larvivorus fishes would be carried out. Larvivorus fish hatcheries would be maintained at 13 villages and fishes would be distributed to the public free of cost, he said.
