The National Vector Borne Disease Control Programme (NVBDCP) classifies malaria-endemic areas using the Annual Parasite Incidence (API). A 'high risk' category district has an API of:

• A < 1 per 1000 population
• B 1–2 per 1000 population
• C > 5 per 1000 population
• D > 2 per 1000 population ✓

Explanation

NVBDCP classifies districts into: low risk (API < 1), moderate risk (API 1–2), and high risk (API > 2 per 1000 population). High-risk districts receive priority for indoor residual spraying, LLIN distribution, and intensive surveillance. API is the gold standard for monitoring malaria transmission intensity.
