HSS

HIV Sentinel Surveillance

The HIV Sentinel Surveillance (HSS) system in India involves carrying out cross-sectional facility and targeted intervention (TI) based HIV sero-prevalence surveys at regular intervals among selected population groups. With HSS, the trends in HIV infection are monitored over the period of time by group and by site. Over the years, the emphasis of HSS in India was on heterosexual transmission, so, the sentinel sites were mainly at antenatal clinics (ANC) and sexually transmitted disease (STD) clinics, to observe the trends and levels of HIV in general population and among people with high risk behavior, respectively.
To know the extent of spread or decline of HIV infection in the State, the HIV Sentinel Surveillance is carried out in antenatal clinics (ANC), patients attending sexually transmitted disease (STD) clinics & individuals belonging to high risk groups (HRG) over the period of 3 consecutive months.
HIV Sentinel Surveillance data is as follows -
