Under the National Vector Borne Disease Control Programme (NVBDCP), the API (Annual Parasite Incidence) threshold above which an area is classified as 'high-risk' for malaria is:

• A API > 1
• B API > 5
• C API > 10
• D API > 2 ✓

Explanation

Annual Parasite Incidence (API) = (Number of positive cases in a year / Population at risk) × 1000. Areas with API > 2 are classified as high-risk (High Endemic) for malaria under NVBDCP and receive intensified interventions including Long-Lasting Insecticidal Nets (LLINs) and Indoor Residual Spraying (IRS). API between 1-2 is moderate risk, and below 1 is low risk.
