Under NACP Phase IV, which surveillance system uses data from pregnant women attending antenatal clinics at sentinel sites to estimate HIV prevalence in the general population?
- A HIV Sentinel Surveillance (HSS) ✓
- B Integrated Biological and Behavioural Surveillance (IBBS)
- C Targeted Intervention programme
- D Link Worker Scheme
Correct answer: A. HIV Sentinel Surveillance (HSS)
Explanation
HIV Sentinel Surveillance (HSS) under NACP monitors trends in HIV prevalence through annual surveys at fixed sentinel sites including antenatal clinics (as a proxy for the general population) and high-risk group clinics. The unlinked anonymous method is used to test blood drawn for routine ANC tests. IBBS specifically surveys high-risk groups (FSW, MSM, IDU) for both behavioural and biological data.
