Men who have sex with men (MSM) and female workers (FSW) are consistently shown to a higher burden of HIV compared other adults in Senegal. This study, Prevention 2.0, evaluates the impact 3-tiered integrated stigma mitigation interventions (ISMIs) approach optimizing service delivery for key populations Senegal.Baseline assessment includes questionnaire biological testing HIV. A proportion participants enrolled into 24-month longitudinal cohort questionnaires every 3 months. In these...
Introduction Transgender women are at high risk for the acquisition and transmission of HIV. However, there limited empiric data characterizing HIV‐related risks among transgender in sub‐Saharan Africa. The objective these analyses is to determine what factors, including sexual behaviour stigma, condom use engagement sex work, contribute HIV infection across three West African nations. Methods Data were collected via respondent‐driven sampling from men who have with (MSM) during three‐...
HIV Self-Testing (HIVST) aims to increase testing coverage and can facilitate reaching the UNAIDS 90-90-90 targets. In Senegal, key populations bear a disproportionate burden of report limited uptake given pervasive stigma criminalization. these contexts, HIVST may represent complementary approach reach reporting barriers engagement with existing routine services. this study, 1839 kits were distributed in 1149 individuals participating pre-test questionnaire 817 post-test questionnaire....
Abstract Introduction Given intersecting biological, network and structural risks, men who have sex with (MSM) transgender women (TGW) consistently a high burden of HIV. Although MSM are key population in Rwanda, there limited epidemiologic data to guide programming. This study aimed characterize HIV prevalence care cascade among TGW Kigali. Methods ≥ 18 years were recruited using respondent‐driven sampling (RDS) from March–August 2018 Participants underwent structured interview including...
Abstract Introduction Key populations including female sex workers ( FSW ) and men who have with MSM bear a disproportionate burden of HIV . However, the role focusing prevention efforts on these groups for reducing country's epidemic is debated. We estimate extent to which transmission among contributes overall in Dakar, Senegal, using dynamic assessment population attributable fraction PAF ). Methods A model , their clients, lower‐risk adult was parameterized calibrated within Bayesian...
In Cote D’Ivoire, there has been limited coverage of evidence-based sexual health services specifically supporting men who have sex with (MSM).

In the mixed and concentrated HIV epidemics of West Africa, relative disproportionate burden among men who have sex with (MSM) compared to other reproductive-age is higher than that observed in Southern Eastern Africa. Our aim describe correlates infection MSM living Lomé, Togo, using Modified Social Ecological Model (MSEM). A total 354 ≥18 years age were recruited respondent driven sampling (RDS) for a cross-sectional survey Togo. Participants completed structured questionnaire tested...
Background and objective: Little information is available on the rapid diagnostic testing for syphilis in Burkina Faso. The objectives of study were (i) to assess sensitivity specificity four site tests comparison with Treponema pallidum haemagglutination assay (TPHA) as a gold standard (ii) evaluate operational characteristics those among health workers maternity unit.Methods: Four commercially Faso evaluated using archived serum samples hemagglutination standard. Blood collected between...
Female sex workers (FSWs) are disproportionately affected by HIV even in the most generalized epidemics. Although structural risks have been understood to affect condom negotiation among FSWs globally, there remain limited data on relationship between determinants of risk, including violence and socioeconomic status, use across sub-Saharan Africa. Here, we describe prevalence their associations with Senegal.
The objective of the study was to assess impact spirulina supplementation on selected anthropometric, biochemical, and hematological parameters HIV-infected adults in Ouagadougou. This quasi-experimental two-arm pilot conducted with infected HIV-1 Ouagadougou, Burkina Faso. A group 50 participants received a 10 gram daily addition antiretroviral treatment (ART) while participant control only ART. At 9 months followup, mean values mid-upper arm circumference (MUAC) hemoglobin were...
Background STIs among men who have sex with (MSM) and transgender women (TGW) continue to increase. In Rwanda, STI management relies on syndromic limited empirical data characterising the burden of specific MSM/TGW. This study evaluated prevalence syphilis, Neisseria gonorrhoeae (NG) Chlamydia trachomatis (CT) associated factors MSM/TGW in Kigali. Methods From March August 2018, 737 >18 years were enrolled using respondent-driven sampling (RDS). Structured interviews HIV/STI screening...
Infection with hepatitis B is a major public health problem in Burkina Faso.
