India committed to eliminating visceral leishmaniasis (kala-azar) as a public health problem under NVBDCP. What quantitative criterion defines elimination at the implementation unit level?

• A Fewer than 1 case per 10 lakh population per year at district level
• B Fewer than 1 case per 1,000 population per year at village level
• C Zero indigenous cases for three consecutive years at state level
• D Fewer than 1 case per 10,000 population per year at block (sub-district) level ✓

Explanation

The agreed elimination target for kala-azar in India, Bangladesh and Nepal is an annual incidence of less than 1 case per 10,000 population at the block or sub-district level, sustained over time. The distractor of less than 1 per 10 lakh is the national TB elimination threshold and is deliberately similar, so candidates must anchor the denominator and the unit correctly.
