Simplified bio-behavioural surveys (BBS-Lite) and HIV data use
5-9 May 2025
Description
Reliable and timely available HIV data are crucial for tracking of the epidemic, program
management and program evaluation activities.
The aim of the course is to provide participants with practical guidance on how to design bio-
behavioural survey “lite” (BBS-Lite), which is a programme-based survey method recently
recommended by WHO and UNAIDS for collecting a limited amount of data in key
populations.1 The course will also address HIV data use more broadly, and give examples of
how different programmatic data sources can be used to improve service delivery.
A simplified bio-behavioural survey (BBS-Lite) does not replace BBS based on probabilistic
sampling, that is surveys based on respondent-driven sampling (RDS) and time-location
sampling (TLS) but rather supplements BBS. This method is less demanding in terms of
implementation and data analysis, less costly than BBS and enables more timely data
availability. It is recommended that this method is implemented more routinely, in-between
rounds of BBS based on probabilistic methods. Participants in BBS-Lite are sampled
through consecutive recruitment of eligible people accessing services (including facility-
based, mobile and outreach services) and through snowball recruitment, which allows for
sampling of both clients and non-clients of services. Presentations and exercises during the
course will address a number of issues relevant for the appropriate design and
implementation of BBS-Lite, data analysis and interpretation. The key advantage of this
method is that it provides faster local-level results to assess the current situation, enabling
community-based organisations to more effectively deliver their services.
The second part of the course will address data use through examples. These will include
BBS data collected via RDS and TLS, and programmatic data sources that can be used to
identify service delivery gaps. Programme-based systems that collect individual level data
generated when a person receives health services can provide rich granular information to
strengthen and monitor programme performance. Unique identifiers in programmatic sources
enable to conduct longitudinal studies of patient and programme outcomes.

Lectures will be followed by discussions about case studies to enable interactive exchange of
knowledge and experiences.
The wealth of information from routine programming should be used to generate context-
specific knowledge on a continous basis to maximize population-level impact.
The workshop will be held at the School of Public Health, Rockefeller str. no 4, Zagreb,
Croatia.
Key topics of the course are:
Sampling frame in BBS-Lite and selection of recruitment sites
Recruitment strategies in BBS-Lite
Questionnaire development and biomarker data collection
Data quality challenges and data interpretation in studies based on BBS-Lite
Use of survey data to assess service delivery gaps and HIV prevention needs
Using routinely collected HIV testing data to measure HIV incidence
Use of routinely collected PrEP data to measure adherence to PrEP and HIV
incidence
Use of HIV phylogenetic analysis to support public health programmes
Participants will be given opportunities to share their own country-specific experiences and
challenges in implementing surveys in KPs and using data.
Key aspects of the course is a group/individual work on development of protocols/ proposals.
Participants can choose between these options:
A. To develop a protocol for a BBS-Lite or a BBS study
B. To develop a protocol/proposal for a study to analyse routinely collected
programmatic data (alternatively, participants can bring their own data and do the
analysis during the course)
Participants will present the results of this work on the final day of the course.
Teaching Methods
The course consists of lectures, presentation of case studies, active discussions, exercises
and group work. The course is designed to provide participants with practical skills and
knowledge on how to design surveillance surveys and more effectively use data.
Target Audience
Epidemiologists, public health professionals, social scientists
Course fee
Course fee is 800 USD and includes lunch and coffee breaks during the course and course
materials.

Dear Colleagues,
WHO Collaborating Centre for HIV Strategic Information is pleased to
announce a training workshop in Simplified bio-behavioural surveys
(BBS-Lite) and HIV data use, which will be held from 5-9 May 2025 in Zagreb,
Croatia. There might be an option for virtual participation, as well. This
training workshop is co-organised with Global Health Sciences, University of
California, San Francisco.
The aim of the course is to provide participants with practical guidance on
how to design bio-behavioural survey “lite” (BBS-Lite), which is a new,
programme-based survey method recently recommended by WHO and UNAIDS for
collecting a limited amount of data in key populations. The course will also
address HIV data use more broadly, and give examples of how different
programmatic data sources can be used to improve service delivery. BBS-Lite
is less demanding in terms of implementation and data analysis, less costly
than BBS based on probabilistic methods and enables more timely data
availability. It is recommended that this method is implemented more
routinely, in-between rounds of BBS based on probabilistic methods such as
RDS and TLS.
The second part of the course will address HIV data use through examples.
These will include use of routine programmatic sources that collect
individual level data, such as HIV testing data that can be used to measure
HIV incidence. Examples will be given of the use of PrEP data to determine
adherence to PrEP, HIV seroconversion and acquisition of STIs, and use of
data to evaluate virtual HIV interventions.
In the attachment please find a more detailed description of the workshop
with the programme, and a course application form.
If interested in applying, please complete a form and send it back to us.
