Vaccination coverage against hepatitis A virus (HAV), hepatitis B virus (HBV), and human papillomaviruses (HPV) is insufficient among men who have sex with men (MSM), partly because of their high prevalence of vaccine hesitancy (VH) specific to these vaccines. This study aimed to investigate determinants of specific VH in MSM, focusing on characteristics of their sexual activity, propensity to use prevention tools and medical care, disclosure of sexual orientation to health care professionals (HCPs), and perceived stigmatization. A cross-sectional electronic survey (February - August 2022) collected perceptions of HBV, HAV, and HPV, and of their respective vaccines among 3,730 French MSM and enabled the construction of a specific VH variable.

In developed countries, vaccinations against hepatitis B (HBV), hepatitis A (HAV), and human papillomavirus (HPV) are often recommended to men who have sex with men (MSM) because of the risky sexual practices in which some engage. Vaccine coverage against these diseases is not optimal in France, probably due in part to vaccine hesitancy (VH). The overall aim of this survey among MSM was to estimate the prevalence of different grades of VH for these vaccines as well as of general VH (toward any vaccine).

HIV is highly prevalent in men who have sex with men (MSM) in West Africa. Many MSM in the region also have sex with women (MSMW). Accordingly, they are a potential bridge subpopulation for HIV transmission to women.

Loss to follow-up (LTFU) from HIV pre-exposure prophylaxis (PrEP) care compromises the goal of HIV elimination. We investigated the proportion of LTFU and associated risk factors among men who have sex with men (MSM) enrolled in a PrEP demonstration project in Burkina Faso, Côte d'Ivoire, Mali, and Togo. CohMSM-PrEP, a prospective cohort study, was conducted between November 2017 and June 2021 in community-based clinics.

We investigated the rate and predictors of ineffective HIV protection in men who have sex with men (MSM) taking pre-exposure prophylaxis (PrEP) in a prospective cohort study from November 2017 to November 2020 in Mali, Côte d'Ivoire, Burkina Faso, and Togo. MSM had to be 18 years or older and at high risk of HIV infection to participate. They also received a comprehensive sexual health prevention package, including PrEP, in community-based clinics as part of the cohort study.

Introduction: Transgender identity is poorly accepted in France, and data on living conditions and the daily difficulties transgender people encounter are scarce. This lack of data reinforces their invisibility in social life, contributes to their stigmatisation and probably increases the burden of HIV infection, especially for HIV-positive transgender people (TRHIV). The main objective of the community-based research study ANRS Trans&HIV is to identify personal and social situations of vulnerability in TRHIV, the obstacles they encounter in terms of access to and retention in medical care, and their gender affirmation and HIV care needs.

Objective: The study aimed to explore longitudinal interactions between homonegativity and sexual behaviors with female partners among HIV-negative West African men who have sex with men and women (MSMW).

Design And Method: The community-based cohort CohMSM ANRS 12324 - Expertise France enrolled MSM in Togo, Burkina Faso, Côte d'Ivoire and Mali. Sociobehavioral data were collected every 6 months.

Background And Objectives: In Mali, the non-governmental association (NGO) ARCAD Santé PLUS launched the CovidPrev program in response to the COVID-19 outbreak to ensure continuity of HIV care-related activities. This study aimed to identify individual and structural factors associated with mental health disorders (MHD) in the NGO's healthcare workers (HCW) in the early stage of the outbreak.

Methods: Data were collected between April 6 and 11, 2020 for 135 HCW in ARCAD Santé PLUS's 18 community-based HIV care centers.

Background: In West Africa, few HIV services target men who have sex with men (MSM). In 2015, the interventional cohort CohMSM started offering a community-based prevention package for MSM. Participants expressed interest in pre-exposure prophylaxis (PrEP) and their eligibility was demonstrated.

The first COVID-19 cases in Mali were reported almost 1 month after the first case in the African continent. However, the outbreak continues to spread faster there than in other countries which, along with Mali, successfully tackled the 2014 Ebola outbreak in Africa. Given this context, specific actions targeting people living with HIV (PLWH) are needed to reinforce prevention.

Although the HIV epidemic is generalized in West Africa, some population groups such as men who have sex with men (MSM), especially those engaged in transactional sex (TS), are thought to be particularly more vulnerable to HIV than others. However, few data are available to help identify their health-related needs with a view to implementing targeted prevention interventions. To fill this knowledge gap, we aimed to characterize MSM reporting TS (MSM-TS) and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM, which was conducted in Burkina Faso, Côte d'Ivoire, Mali and Togo.

Female sex workers (FSW) in mining sites are considered to be at very high risk of HIV infection. We aimed to characterize FSW at the Kôkôyô artisanal gold mining site in Mali, and identify factors associated with sex work using data from ANRS-12339 Sanu Gundo, a cross-sectional survey conducted in 2015 at the mine by ARCAD-SIDA, a Malian non-governmental organisation. People attending HIV-prevention activities were invited to participate in the quantitative and qualitative parts of the survey.

Understanding the dynamics of HIV infection in men who have sex with men (MSM) can help improve efficiency in existing prevention strategies. We aimed to identify and describe the sexual behaviors of MSM most at risk of HIV infection in West Africa. HIV-negative MSM were provided a quarterly preventive follow-up package in the community-based cohort CohMSM.

Objectives: Whether regular HIV testing and counselling reduce risky sexual behaviours in African men who have sex with men (MSM) is still a matter for debate. We aimed to identify behavioural trajectories based on HIV risk exposure (HRE) and factors affecting their evolution.

Methods: Data were collected from 621 HIV-negative West African MSM (Mali, Cote d'Ivoire, Burkina Faso and Togo) included in a community-based cohort providing quarterly HIV testing and counselling.

Research on male clients of male sex workers (MCMSW) has been neglected for a long time globally. We aimed to characterize MCMSW and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM conducted in Burkina Faso, Côte d'Ivoire, Mali and Togo. Our study focused on HIV-negative men who have sex with other men (MSM), recruited between 06/2015 and 01/2018 by a team of trained peer educators.

Objective: To explore the interest in taking PrEP among Western African men who have sex with men (MSM).

Methods: A cross-sectional survey was implemented at enrolment of HIV-negative MSM in a multiple centre community-based cohort study in four West African countries (Mali, Côte d'Ivoire, Burkina Faso, Togo). A standardised face-to-face questionnaire collected data on socio-demographic and behavioural characteristics over the previous 6 months.

Objectives: The aim of this article was to estimate HIV prevalence and the factors associated with HIV seropositivity in the population living and working at the informal artisanal small-scale gold mining (IASGM) site of Kokoyo in Mali, using data from the Sanu Gundo survey. Our main hypothesis was that HIV prevalence is higher in the context of IASGM than in the country as a whole.

Design: The ANRS-12339 Sanu Gundo was a cross-sectional survey conducted in December 2015.

In addition to being the targets of frequent discrimination and violence,African men who have sex with men (MSM) are being hit hard by the HIV/AIDS epidemic. Although there is still insufficient research regarding the methods of HIV transmission in sub-Saharan Africa, several studies show that the prevalence of HIV infection among MSM is more than ten times higher than among the general population.
