Which drug regimen is used during mass drug administration (MDA) rounds for lymphatic filariasis elimination in endemic districts of India?

• A Annual single dose of diethylcarbamazine 3 mg/kg alone
• B Twice-yearly single dose of praziquantel 40 mg/kg
• C Daily diethylcarbamazine 6 mg/kg for 12 days to the entire population
• D Annual single dose of diethylcarbamazine 6 mg/kg plus albendazole 400 mg ✓

Explanation

The MDA regimen is a single annual dose of DEC 6 mg/kg with albendazole 400 mg to all eligible residents for at least five consecutive rounds, aiming to interrupt transmission. Some districts have shifted to the triple-drug IDA regimen adding ivermectin, but DEC plus albendazole remains the core two-drug regimen. The 12-day DEC course is individual treatment for microfilaraemic cases, not MDA.
