Filaria is a serious lymphatic disease. The transmission of filarial takes place through mosquito’s culex quinquefasciatns. The infected person suffering from this disease develops swellings of limbs which keep on increasing making the person incapacitated and suffering from social stigma as well.

Apart from these problems person also suffers from frequent attacks of lymphangitis, high fever, swelling and pain. There is no cure at this stage and person is forced to live with huge swellings. This disease has been reported from 250 districts in 20 states and UTS where over 500 million people are affected. Filaria is also a major health problem in India.

For control of filaria, the National Filaria Control programme was launched in 1955. Under this programme, various activities are being undertaken such as

(i) Delimitation of the problem in hitherto unsurveyed areas

ADVERTISEMENTS:

(ii) Control of filarial in urban areas through recurrent anti- larval measures and antiparasitic measures.

The National Filaria Control Programme also carries out anti- larval mosquito measures, establishing filaria clinics and making provision for under ground drainage. A pilot project on single dose annual mass DEC drug administration was undertaken during 1997 in 13 districts of 7 endemic states, covering a population of about 41 million.

The National Health policy 2002, has envisaged the goal of filaria elimination by the year 2015. In the year 2004, 202 districts of 20 states with a population of 407 million were targeted for Mass Drug Administration. Under the National Filaria Control Programme, training is also being imparted at three regional Filaria Training and Research Centers, situated at Calicut, Rajamundary and Varanasi. These training centers are under the supervision of the National Institute of Communicable Diseases of Delhi
