Assessing Outcomes in HIV Prevention and treatment Programmes with Key Populations, in Nairobi, Kenya: enhanced Polling Booth Survey (ePBS)

The study aims to assess the HIV prevention outcomes in programmes with female sex workers (FSW) and men who have sex with men (MSM) in Nairobi, Kenya. The study will use polling booth method, a novel data collection tool used to collect behavioral data. It is a group interview method in which individuals provide responses through a ballot box in an unlinked and anonymous way. The sample size for the quantitative survey is 680 FSW and 379 MSM. Sampling procedure will use a two-stage i) random selection of participants ii) HIV rapid tests will be conducted for all consenting participants; urine rapid tests will be conducted for all those who report to be on PrEP to test for tenofovir and blood samples will be collected from all those who are positive to test for HIV recency and viral suppression.


  • To estimate the incidence and prevalence of HIV among key populations (female sex workers and men who have sex with men) in Nairobi, Kenya
  • To assess biomedical (condom use, PrEP uptake, 95-95-95 cascade), behavioural (knowledge and risk behaviours) and structural outcomes (experience of violence, stigma and discrimination) of the KP programme in Nairobi, Kenya
  • To assess access and use of comprehensive package of HIV prevention and treatment services among key populations in Nairobi, Kenya
  • To understand the barriers contributing to gaps in access and utilization of services among key populations

Project Initiated 2023

The study was initiated in March 2023.

The study population includes two key population groups: female sex workers and men who have sex with men and will take place in 4 groups where a sample size of each group will be divided by an average of 10-12 respondents per Polling Booth Surveys (PBS) to arrive at the number of PBS to be conducted. The study will be using the list of locations and the population size estimation of mapping conducted in the year 2018 and a will take place in 17 sub-counties in Nairobi county.
