For elimination of visceral leishmaniasis (kala-azar) under NVBDCP, the national target defines elimination at which administrative level and threshold?

• A Fewer than 1 case per 100,000 population per year at district level
• B Fewer than 1 case per 10,000 population per year at block (sub-district) level ✓
• C Zero indigenous cases nationally for three consecutive years
• D Fewer than 1 case per 10 lakh population per year at state level

Explanation

India adopted the regional kala-azar elimination goal of reducing annual incidence to below 1 case per 10,000 population at the block or sub-district level, because transmission is highly focal and district-level averages would mask persistent pockets. Option D describes the TB elimination threshold (<1 per 10 lakh), a common confusion point, while option A misstates both the denominator and the level used for leprosy-related indicators.
