A district in Bihar has been classified as endemic for lymphatic filariasis based on antigenaemia surveys. According to NVBDCP strategy, which mass drug administration regimen should be implemented?

• A Albendazole 400 mg alone as a six-monthly dose for four rounds
• B Ivermectin 200 mcg/kg twice yearly for two consecutive years
• C Diethylcarbamazine 6 mg/kg daily for twelve consecutive days each year for three years
• D Diethylcarbamazine 6 mg/kg plus albendazole 400 mg as a single annual dose for a minimum of five rounds ✓

Explanation

The NVBDCP MDA strategy for bancroftian filariasis uses a single annual co-administration of diethylcarbamazine citrate 6 mg/kg with albendazole 400 mg, delivered for at least five consecutive effective rounds with coverage above 65 percent to interrupt transmission. Albendazole alone or ivermectin-based regimens are not used for Indian MDA, and DEC alone as a short daily course does not achieve the macrofilaricidal effect needed for community-level control.
