PHDA collaborates with several organizations to implement its programmes. Collaboration has had a huge impact on our work related to research, programme delivery, and health policies. Some of our key partners are:

Partnership with Government

  • PHDA has developed partnerships with the National AIDS and STI Control Programme (NASCOP) and the National AIDS Control Council (NACC) under the Ministry of Health. This formal partnership is in its 9th year and has helped in strengthening the HIV prevention programme in Kenya.
  • PHDA also works with the county governments in almost 37 counties through the technical support it provides for key population programmes. PHDA works closely with the Nairobi Metropolitan Services as it delivers health services through the SWOP clinics in Nairobi. This collaboration has helped in delivering harm reduction services and reducing gender-based violence among some of the marginalized populations in Nairobi.

Partnerships with Community-led Organisations and other Civil Society Organisations

  • PHDA works in partnership with several community-led organizations especially in the design and implementation of research and programmes. We have built strong partnerships with organizations like HOYMAS, SWOP Ambassadors, MPEG, MAAYGO, HAPA Kenya, and Link to Smile. This collaboration has strengthened capacities, improved the quality of research and programmes and helped in achieving the desired outcomes effectively.
  • PHDA has also partnered with other civil society organizations like ICRH, Jhpiego, Genesis Analytics, FHI 360, and SWOP Kenya in research and programme delivery.

Partnership with Research Organisations and Academic Institutions

  • PHDA researches global health and has partnered with research organizations like Nyanza Reproductive Health Society, KAVI, IAVI, KEMRI. PHDA is also part of a research consortium called MSM Health Research Consortium in Kenya.
  • PHDA partners with various academic institutions to conduct research. Partnerships have been established with the London School of Hygiene and Tropical Medicine University of Toronto, University of Manitoba (UoM), University of Nairobi (UoN), University of Central Lancashire (UCLAN). PHDA in partnership with the UoM also provides training for students from the University. In partnership with the UoM and the UoN, PHDA also organizes the annual Scientific Conference to provide space for
    young researchers to share their work.

Partnerships with Funders

  • To conduct research, deliver programmes, and provide technical support, PHDA has partnered with several funding agencies. These agencies include the Bill & Melinda Gates Foundation, USAID, CDC, OSIEA, Fund for Innovation and Transformation, Global Fund, IAVI.



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.
