The National Kala-azar Elimination Programme sets an elimination threshold that a district or sub-district (block) must achieve and sustain. What is this threshold?

• A Annual incidence below 1 case per 1000 population
• B Annual incidence below 1 case per 10,000 population ✓
• C Prevalence below 5 cases per 10,000 population
• D Zero indigenous cases for 3 consecutive years

Explanation

Kala-azar elimination in India, Bangladesh and Nepal is defined as an annual incidence of less than 1 case per 10,000 population at the district and sub-district (block) level, sustained over time. Note the contrast with TB elimination, where the aspirational benchmark is less than 1 per lakh, so students who confuse the two denominators lose this item.
