The Ministry of Health and Social Welfare and the Tanzania Commission for AIDS have expressed a need for key population HIV prevalence and group size estimates to identify the costs of the Third National Multi-Sectoral Strategic Framework on HIV and AIDS; the Third Health Sector HIV and AIDS Strategic Plan (HSHSP III); and other HIV prevention, care, and treatment strategies.
With support from the Health Policy Project (HPP), which is funded by the United States Agency for International Development (USAID), NACP held a one-day workshop on April 14, 2014, to discuss and reach consensus among key stakeholders on key population estimates for mainland Tanzania. The consensus-building workshop reviewed the existing evidence and evaluated specific studies with a view to identifying study limitations and knowledge gaps. A Delphi method was used to seek consensus on the estimated size of and HIV prevalence among the three key populations in Tanzania: female sex workers (FSWs), men who have sex with men (MSM), and people who use/inject drugs (PWUD/PWID). Due to the uncertainty and lack of empirical data surrounding prior estimates of these indicators for mainland Tanzania, the Delphi method was used to garner the highest-quality and least- biased estimates possible. Each key population group had an expert panel of 9 to 14 people, each with extensive experience in and knowledge of the key population group in the Tanzanian context.
