Impact of scaling up harm reduction interventions on injecting risk behaviours, ART outcomes and HIV incidence among people who inject drugs in Kenya
This study provides strong evidence for the benefits of NSP and OAT on varied HIV outcomes among PWID in Africa
“We only trust each other”
In Kenya, overdose remains a major public health concern with approximately 40% of persons who inject drugs (PWID) reporting personal overdoses. PWID living with HIV (PWID-LH) are particularly vulnerable to experiencing fatal and non-fatal overdoses because of the surrounding physical, social, economic, and political environments, which are not fully understood in Kenya. Through qualitative inquiry, this study characterizes Kenya’s overdose risk …
Assessing awareness and use of HIV self-testing kits after the introduction of a community-based HIV self-testing programme among men who have sex with men in Kenya
Men who have sex with men (MSM) bear a disproportionate burden of new HIV infections in Kenya, while experiencing discrimination, leading to suboptimal levels of HIV care. HIV self-testing (HIVST) is a tool to increase HIV screening and earlier diagnosis; however, questions remain regarding how best to scale-up HIVST to MSM in Kenya. The main objective of this study was to examine changes in knowledge and use of HIVST after implementation of a co…
From collaborator to colleague
Since the 1990s, researchers have used community-based participatory approaches to achieve outcomes relevant to local communities, to build collaborative and sustainable research infrastructures, and to address disparities in knowledge production. Notwithstanding these strengths, communities and researchers have questioned its success in addressing power imbalances inherent in collaborative research encounters. In this methodological paper, we de…
Predictors of hepatitis C cure among people who inject drugs treated with directly observed therapy supported by peer case managers in Kenya
Challenges and best practices for hepatitis C care among people who inject drugs in resource limited settings
People who inject drugs (PWID) living with Hepatitis C (HCV) in low- and middle-income countries face substantial barriers to HCV care. We sought to gain healthcare providers' perspectives on challenges and best practices for HCV care provision among PWID in Kenya. We conducted three focus group discussions (FGD) with 23 healthcare providers working with PWID living with HCV in Nairobi and Mombasa. Transcribed interviews were analysed thematicall…
Understanding socio-sexual networks
Willingness to use HIVST was nearly universal and points to the importance of networks for reaching individuals not enrolled in programs. Network analysis can help in understanding which type of networks had higher testing and how network-based approaches can be useful to promote HIVST in certain contexts
Validity and reliability of the Neilands sexual stigma scale among Kenyan gay, bisexual, and other men who have sex with men
Our findings suggest enacted and perceived sexual stigma are distinct yet closely related constructs among GBMSM in Kenya and are associated with poor mental health and substance use
Impact of Covid-19 on substance use disorder treatment services in Kenya
Remaking the Technosubject
The Kenyan government offers free HIV self-testing kits to men who have sex with men. The value of self-testing is based on the imaginary of an autonomous technosubject empowered to independently control testing services, thereby "freed," through technology, from the social conditions that might inhibit health services utilization. Following a community-centered collaborative approach, community researchers interviewed their peers who examined an…
An intensive model of care for hepatitis C virus screening and treatment with direct‐acting antivirals in people who inject drugs in Nairobi, Kenya
BACKGROUND AND AIMS: Hepatitis C virus (HCV) treatment is essential for eliminating HCV in people who inject drugs (PWID), but has limited coverage in resource-limited settings. We measured the cost-effectiveness of a pilot HCV screening and treatment intervention using directly observed therapy among PWID attending harm reduction services in Nairobi, Kenya. DESIGN: We utilized an existing model of HIV and HCV transmission among current and forme…
Hepatitis C-related knowledge, attitudes and perceived risk behaviours among people who inject drugs in Kenya
Despite disproportionately high rates of Hepatitis C (HCV) among people who inject drugs (PWID) in low- and middle-income countries (LMICs), understanding of HCV-related knowledge, attitudes and perceived risk behaviours among this population remains limited. We aimed to elucidate knowledge, attitudes and experiences that could minimise transmission risk and maximise HCV treatment engagement among PWID in Kenya following the integration of HCV sc…
Beyond biomedical and comorbidity approaches
We explored general health and psychosocial characteristics among male sex workers and other men who have sex with men in Nairobi, Kenya. A total of 595 MSM/MSW were recruited into the study. We assessed group differences among those who self-reported HIV positive (SR-HIVP) and those who self-reported HIV negative (SR-HIVN) and by affinity group membership. Quality of life among SR-HIVP participants was significantly worse compared to SR-HIVN par…
The effects of Covid-19 on the health and socio-economic security of sex workers in Nairobi, Kenya
The COVID-19 pandemic, and its attendant responses, has led to massive health, social, and economic challenges on a global scale. While, so far, having a relatively low burden of COVID-19 infection, it is the response in lower- and middle- income countries that has had particularly dire consequences for impoverished populations such as sex workers, many of whom rely on regular income in the informal economic sector to survive. This commentary cap…
Low program access despite high burden of sexual, structural, and reproductive health vulnerabilities among young women who sell sex in Mombasa, Kenya
SDG-related vulnerabilities begin early in the lives of YSW who are not currently reached by programs designed for female sex workers
Evaluation of community-based HIV self-testing delivery strategies on reducing undiagnosed HIV infection, and improving linkage to prevention and treatment services, among men who have sex with men in…
This study is one of the first programme science studies in Sub-Saharan Africa exploring the effectiveness of integrating HIVST interventions within already existing HIV prevention and treatment programmes for MSM in Kenya at scale. Findings from this study will inform national best approaches to scale up HIVST among MSM in Kenya
Effects of Exposure to an Intensive HIV-prevention Programme on Behavioural Changes among Female Sex Workers in Nairobi, Kenya
While Kenya has had a long-standing national HIV-prevention program, evidence on the level of exposure to its interventions and related effects on behavioral changes among female sex workers (FSWs) is limited. Using cross-sectional behavioral data collected in 2013 from 1 357 FSWs aged 18 years and above in Nairobi, Kenya, this study explores the relationship between FSW program exposure levels and behavioral outcomes including condom use, sexual…
Ecologies of security
This paper highlights important environmental dimensions of HIV vulnerability by describing how the sex trade operates in Nairobi, Kenya. Although sex workers there encounter various forms of violence and harassment, as do sex workers globally, we highlight how they do not merely fall victim to a set of environmental risks but also act upon their social environment, thereby remaking it, as they strive to protect their health and financial interes…

Risk Factors for HIV Acquisition in a Prospective Nairobi-Based Female Sex Worker Cohort
Prevalence of HIV, Sexually Transmitted Infections, and Risk Behaviours Among Female Sex Workers in Nairobi, Kenya
HIV and STI Prevalence and Injection Behaviors Among People Who Inject Drugs in Nairobi
There is a dearth of evidence on injection drug use and associated HIV infections in Kenya. To generate population-based estimates of characteristics and HIV/STI prevalence among people who inject drugs (PWID) in Nairobi, a cross-sectional study was conducted with 269 PWID using respondent-driven sampling. PWID were predominantly male (92.5 %). An estimated 67.3 % engaged in at least one risky injection practice in a typical month. HIV prevalence…
