Mass administration of DEC tablets is still crucial in preventing spread of filariasis

As filariasis (lymphatic filariasis) continues to be a major health hazard in tropical and subtropical regions, the timely dosage of DEC tablets is the only vital preventive measure against the spread of filariasis caused by parasitic worms transmitted through mosquito bites.

Institute of Applied Dermatology (IAD) director Dr S R Narahari says that the state governments in India have been undertaking mass administration of Diethylcarbamazine citrate (DEC) tablets to combat the spread of filariasis and that's the most effective way to eradicate this debilitating disease. "Diethylcarbamazine citrate (DEC) tablets have been widely used in the prevention and treatment of filariasis. We need to continue with mass administration of DEC tablets to further contain the spread of filariasis," he said, adding that DEC effectively kills the microfilariae (larval stage) of the parasite, reducing the risk of infection and progression of the disease. Dr Narahari further pointed out that it was essential to follow a strict dosing schedule of DEC tablets to get the desired results.

"In localities and regions where filariasis cases are reported, we need to organize mass drug administration campaigns targeting entire communities or specific high-risk groups. We must sensitise people about the need to take the DEC tablets and complete the full course of treatment even if they are not exhibiting any symptoms," Dr Narahari said adding that the DEC tablets which kill the larval forms of the parasite prevent the development of chronic and disabling conditions associated with filariasis which included lymphedema (swelling of the limbs), elephantiasis (severe swelling and thickening of the skin), and hydrocele (swelling of the scrotum in males).
