In India's NVBDCP, what is the current definition of 'Annual Parasitic Incidence (API)' threshold above which a district is classified as a 'High-Burden District' for malaria?

• A API ≥ 1 per 1000 population ✓
• B API ≥ 2 per 1000 population
• C API ≥ 5 per 1000 population
• D API ≥ 10 per 1000 population

Explanation

API (Annual Parasitic Incidence) = (Confirmed malaria cases in a year / Population under surveillance) × 1000. Under NVBDCP's stratification, districts with API ≥ 1 per 1000 population are classified as High Burden Districts and receive intensified vector control, surveillance, and case management resources. As India progresses toward malaria elimination, many states have achieved API < 1. The overall goal is to reduce API to <1 nationally and then achieve zero indigenous cases.
