HIV Sentinel Surveillance

NIHFW has been entrusted with the responsibility of coordinating, monitoring, data quality and to prepare the country report of the Annual Sentinel Surveillance (HSS) activities since its inception, i.e. 1998. HSS was an annual exercise from 1998 till 2007. From 2008 onwards the HSS was done once in two years.


Objectives of HIV Sentinel Surveillance

  • • Monitor trends in prevalence of HIV infection over time.
  • • Monitor the distribution and spread of HIV prevalence in different population subgroups and in different geographical areas.
  • • Identify emerging pockets of HIV epidemic in the country.


Applicaiton of HIV Sentinel Survillance

  • • To estimate and project burden of HIV at state & national levels.
  • • To support programme prioritization and resource allocation.
  • • To assist evaluation of programme impact.
  • • Advocacy.

Current Status

The 14th round of HIV Sentinel Surveillance was conducted during 2014-15 for Antenatal Clinic sites. In this round a total of 768 ANC sites included for surveillance across the country.

Currently the NIHFW is coordinating the ongoing 15th round of HSS (2016-17) among ANC and HRG sites across the country. This round of surveillance is proposed to be implemented at 877 ANC and 551 HRG sites. Almost every district of the country has one or more sentinel site.

Integrated Behavioral and Biological Surveillance

Integrated Behavioral and Biological Surveillance (IBBS) was introduced for the first time, at the national level, to strengthen surveillance among High Risk Groups and bridge population and to generate evidence on prevalence and risk behaviors among HRGs and bridge population. NIHFW was a part of Technical Advisory Group to frame the design of IBBS. The activities under IBBS were Pre-Survey Assessment (PSA), sample frame development (SFD), community preparation and data collection. NIHFW has been identified as a "Regional Institute" for conducting IBBS for Delhi and Rajasthan. There were 9 domains in Delhi and 9 domains in Rajasthan. In all domains a total of 10,013 samples were collected among them 5,186 were from Delhi and 4,827 were from Rajasthan. The distribution of domains and sample collected in NIHFW region is given in below link.

As per guidelines of NACO for conduction of IBBS, NIHFW was involved in the following activities:

  • a. Conduction of regional ToT for State Surveillance Team and Field Research Agency (IMRB)
  • b. Monitoring of the recruitment process of the survey teams
  • c. Mentoring and monitoring the state level trainings
  • d. Monitoring, supervision and on field capacity building of the survey teams during the SFD and survey phase
  • e. The SFD data were verified and approved in Integrated Information Management System (IIMS)
  • f. Mentoring and monitoring the state level refresher trainings for data collection
  • g. Monitoring the timeliness of the flow of blood samples (Dried Blood Spot) from the field to the testing labs and timeliness of testing process and uploading of testing results on IIMS at designated laboratories
  • h. The timeliness of the data collection and the quality of the data were monitored through the IIMS. The field teams were given feedbacks/instructions based on observations made.
  • i. The quality check of data done before final freezing for HRGs (High Risk Groups), Migrants and Currently Married Women domains of both the states.
