A village in an implementation unit undergoing Mass Drug Administration for lymphatic filariasis under NVBDCP receives its annual round. Which regimen and duration define the standard MDA strategy for interrupting transmission?

• A Ivermectin alone, twice yearly for 3 years
• B Diethylcarbamazine plus albendazole, single annual dose for a minimum of 5 years ✓
• C Diethylcarbamazine daily for 12 days, repeated every 6 months indefinitely
• D Albendazole plus praziquantel, single dose for 2 years

Explanation

The GPELF-endorsed regimen used in India is a single annual dose of diethylcarbamazine citrate (6 mg/kg) plus albendazole 400 mg, given for at least 5 consecutive rounds to cover the lifespan of the adult worm. Ivermectin-containing regimens are not the standard Indian MDA, and DEC given daily for 12 days is the individual patient treatment course, not community MDA.
