The National Vector Borne Disease Control Programme (NVBDCP) classifies malaria endemicity using the Annual Parasite Incidence (API). A district with API >2 is classified as:

• A Low risk
• B Moderate risk (Category I)
• C Category III — highest intervention priority
• D High risk (Category II) ✓

Explanation

Under NVBDCP, districts are stratified by Annual Parasite Incidence (API): Category I (API 1–2, moderate risk) and Category II (API >2, high risk requiring intensified interventions such as enhanced vector control, drug distribution, and surveillance). Category III (API ≥5 in some classifications) is used for tribal/forest districts. Low-risk districts have API <1. API = (confirmed malaria cases / total population) × 1000.
