VECTOR BORNE DISEASE CONTROL PROGRAMME

??????????? The Programme for the control of Vector Borne Disease, Malaria, Filariasis, Guinea Worm Eradication and Japanese Encephalitis are under implementation in the State of Tamil Nadu.? The Director of Public Health and Preventive Medicine, Chennai is the Programme Director.? He is assisted by the Additional Director of Public Health and Preventive Medicine (Malaria & Filaria) and Joint Director (VBDC) in the implementation of the Programme.

MALARIA SITUATION IN TAMIL NADU

??????????? In Tamil Nadu State, during 90s a total of 1,20,029 cases were recorded out of which 59.6% were recorded from the Urban areas and 40.4% in Rural.? The coastal villages of Ramanathapuram, Paramakudi, Nagapattinam and riverine villages of Dharmapuri, Krishnagiri and Tiruvannamalai were endemic for Malaria.? Due to the intensive control measures like active and passive surveillance, Vector control measures etc., taken up by the Public Health Department, the malaria case incidence has been drastically brought down to 34510 in 2002.

??????????? At present the coastal villages of Nagapattinam, which were once endemic are almost free from Malaria.? The incidence of Malaria in Tiruvannamalai shows a decreasing trend.? However, Malaria is emerging as a problem in Ramanathapuram.? The factors contributing for the persistence of Malaria in rural areas are:-

1)?????? Numerous breeding places in the river beds, puddles, rocky pits, sandy pits, casuarinas??? ?pits, etc.,

2)?????? Migration of the population for fishing (Ramanathapuram), as labourers for construction and as quarry workers to other endemic states.

3)?????? Non-acceptance for indoor residual spray.

Out of the total Malaria cases reported in the State, 78% are occurring in Chennai City and another 6% in Tuticorin, Erode, Vellore, Dindigul, Salem, Tiruchengode, Tiruvallur and Tiruvottiyur.? The following problems attribute for the increase of Malaria in Urban areas.

1)?????? Population migration in search of employment.

2)?????? Lack of adequate water supply leading to storage of water for use, creating breeding source of Malaria Vector.

3)?????? Developmental activities especially construction of Buildings, over-bridges etc.,

4)?????? Non closure of wells, cisterns, overhead tanks etc.,

5)?????? Inaccessible overhead tanks causing hindrance to the anti-larval work.

CONTROL STRATEGY:

??????????? The control strategies adopted in the Public Health Department are:-

1)?????? Malaria case detection is being carried-out by house to house visit by collection of blood smears from fever cases and giving treatment for those who are found positive for Malaria.

2)?????? Two rounds of residual insecticidal spray during transmission period using synthetic pyrethroids in Malaria endemic areas.

3)?????? Passive surveillance and anti-larval work in Urban.

4)?????? Creating awareness among the community for their participation.

5)?????? Whenever imported cases are recorded, the same is cross notified by the concerned Medical Officer to the respective Health Authorities of State for further remedial action at their end.

6)?????? Mass and contact Blood survey are being carried out to prevent the occurrence of Secondary cases in the low risk areas.

7)?????? Whenever necessary, focal spray is being carried out.

In Tamil Nadu I.E.C. activities have made a great impact on surveillance, that more number of cases are being identified under passive surveillance than Active Surveillance.

??????????? Geographical information system (GIS) is being developed in Tamil Nadu for carrying-out epidemiological mapping of the villages and for identifying vulnerable areas and seasonal pattern of disease outbreak.

??????????? The incidence of Malaria for the past 4? years are furnished below:
