Under the National Programme for Elimination of Lymphatic Filariasis (NPELF), the strategy used for mass drug administration (MDA) in endemic districts is:
- A DEC + Albendazole annually (Triple Drug Therapy with Ivermectin in some areas) ✓
- B Diethylcarbamazine (DEC) alone annually
- C Ivermectin alone annually
- D Albendazole + Ivermectin biannually
Correct answer: A. DEC + Albendazole annually (Triple Drug Therapy with Ivermectin in some areas)
Explanation
India's NPELF MDA strategy uses DEC (6 mg/kg) + Albendazole (400 mg) annually in endemic districts. Following WHO guidance, Triple Drug Therapy (IDA: Ivermectin + DEC + Albendazole) has been introduced in some districts as it accelerates transmission interruption. DEC kills microfilariae and adulticidal effect is partial; Albendazole targets adult worms. Treatment coverage target is ≥65% of eligible population.
