Under NVBDCP's revised malaria strategy, which criterion defines a 'high-burden high-impact' district warranting intensified interventions?

• A Annual Parasite Incidence (API) ≥ 1 per 1000 population ✓
• B Slide Positivity Rate (SPR) > 10% sustained over two consecutive years
• C Annual Blood Examination Rate (ABER) < 10% in the district
• D Proportion of P. falciparum cases >50% of total malaria cases

Explanation

India's National Framework for Malaria Elimination 2016–2030 classifies districts by Annual Parasite Incidence (API). An API ≥ 1 per 1000 population designates a district as high-burden requiring intensified vector control, universal LLIN distribution, and indoor residual spraying. API is calculated as number of confirmed malaria cases/population at risk × 1000. Districts with API < 1 are targeted for elimination, while API ≥ 2 triggers category 1 (highest-risk) classification.
