Under the National Vector Borne Disease Control Programme (NVBDCP), which of the following is the CORRECT API (Annual Parasite Incidence) threshold above which indoor residual spraying (IRS) is mandated in a district?

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

Explanation

Under NVBDCP, IRS with insecticides is prioritized in areas with Annual Parasite Incidence (API) > 1 per 1000 population per year. Districts with API ≥ 2 are classified as high-burden and receive intensified control interventions. API = (total confirmed malaria cases/total population) × 1000.
