 Sentinel Surveillance |
HIV sentinel surveillance means carrying out cross sectional study of HIV sero prevalence rates at regular interval among selected groups in the population known as "sentinel groups".
|
Annual HSS was started in 1998 and is being conducted regularly every year, with the objective
- To provide understanding of the spread of HIV infection.
- To determine geographical distribution and time trend of infection.
- To provide a basis for prioritization of resources.
- Validation of data from other sources.
- Evaluation of the national response to various programmes.

HIV sentinel surveillance was conducted in 41 sites. Results showed mean positivity in ANC cases 0.19%, almost level as compared to the previous years. Mean HIV prevalence in STD group turned out to be 2.16 depicting rising trend while Sentinel Surveillance of FSW group shows similar mean value.

- Jalor & Dungarpur Districts in Rajasthan have come up near as Category A district in 2008 round showing HIV positivity of 1% & 0.94% respectively
- Chittorgarh, Jaipur and Sikar has shown prevalence of around 5% while Ajmer has shown 8.8% positivity in STD group.
- Dungarpur, Jalor, Sikar & Rajsamand emerging as hot spot.
- Except of Ajmer & Jaipur remaining districts of category A & B are showing prevalence of less than 1% in ANC and less than 5% in STD cases .
- Category A district Ganganagar FSW site is showing 0 positivity in FSW , while Category B districts Ajmer& Alwar have shown 7.2% positivity.
- Rajasthan was able to keep the prevalence less than one percent in the general population keeping there by in the low prevalence category
- . With the prevalence in & around 5% in high risk sites the spillage in general population appeared to be eminent but contrary to the expectation no statistically significant change was observed in the prevalence of ANC sites.
- Even the scaling of the SS ANC sites could bring out significant change in the HIV prevalence in general population showing fairly well controlled epidemic in state.
- On 90 % CI there is definite decline in the mean prevalence of HIV among the STD group.
