Q.1 What is HIV Sentinel Surveillance?
Ans. HIV Sentinel Surveillance is done every alternate year across the nation among ANC (pregnant women) and HRG. Predetemined sample size is collected.
Q.2 What is “Unlinked Anonymity” in HIV Sentinel Surveillance?
Ans. In HIV Sentinel Surveillance, unlinked anonymity means that the blood is primarily collected for some other purpose and the results are not linked to any individual. This methodology is adopted in order to minimise participation bias in the whole procedure.
Q.3 Is the HIV Sentinel Surveillance clinic based or community based?
Ans. In order to minimise the selection bias of samples, consecutive sampling procedure is adopted and it is ideally a clinic based approach.
Q.4 What is the usefulness of HIV Sentinel Surveillance?
Ans. HIV Sentinel Surveillance data is used to understand and monitor time trends, know HIV prevalence levels in various risk groups in states/UTs and work out total HIV burden in various sub-populations.
