Local initiative supports case isolation and contact tracing during a Sars-CoV-2 surge in summer 2020
In Antwerp, Belgium's second largest city, a COVID-19 surge in July 2020 predominantly affected neighborhoods with high ethnic diversity. Local volunteers reacted and set up an initiative to support contact tracing and self-isolation. We describe the origin, implementation, and transfer of this local initiative, based on semi-structured interviews of five key informants and document review. The initiative started in July 2020, when family physici…
Understanding why and how youth-friendly health services improve viral load suppression among adolescents and young people living with HIV in Nigeria
INTRODUCTION: Youth-friendly health service (YFHS) approaches are essential to better outcomes for young people. We evaluated attainment of viral load suppression among young people living with HIV (YPLHIV) enrolled in an HIV treatment programme implementing YFHS models in Nigeria. METHODS: A realist evaluation using qualitative and quantitative programme data from 10 implementing health facilities. We used qualitative information to explore how …

“No good man will ever want me”. How structural social inequality increases women’s vulnerability to HIV transmission
Understanding the pathways that expose women to HIV transmission are vital in improving HIV prevention, especially among a "hidden" group of women without pre-established known risk for HIV. We investigated the pathways which place certain women at greater risk for HIV in a qualitative exploratory study with theoretical sampling using an emergent theory study design in an urban setting in Indonesia. We conducted semi-structured interviews with 47…
Awareness of, Willingness to Take PrEP and Its Actual Use Among Belgian MSM at High Risk of HIV Infection
The social meanings of PrEP use - A mixed-method study of PrEP use disclosure in Antwerp and Amsterdam
Pre-Exposure Prophylaxis (PrEP) is a novel HIV prevention tool. PrEP stigma is a frequently reported barrier, while social disclosure of PrEP use may be an important facilitator. We explored how PrEP users managed PrEP use disclosure using a symbolic interactionist approach. We interviewed 32 participants from two PrEP demonstration projects (Be-PrEP-ared, Antwerp; AMPrEP, Amsterdam). We validated qualitative findings through Be-PrEP-ared questio…
Multilevel modelling and multiple group analysis of disparities in continuity of care and viral suppression among adolescents and youths living with HIV in Nigeria
INTRODUCTION: Substantial disparities in care outcomes exist between different subgroups of adolescents and youths living with HIV (AYLHIV). Understanding variation in individual and health facility characteristics could be key to identifying targets for interventions to reduce these disparities. We modelled variation in AYLHIV retention in care and viral suppression, and quantified the extent to which individual and facility characteristics acco…
Drug use, depression and sexual risk behaviour
Little is known about how interacting psychosocial problems may influence sexual behaviour among men having sex with men taking Pre-exposure prophylaxis (PrEP). This study assessed (1) the prevalence of depression, recreational drug-use and sexual risk behaviour; (2) changes in these psychosocial conditions over time; and (3) the interaction of drug use and depression with sexual risk behaviour. We analysed data of the Belgian Be-PrEP-ared cohort…
The Impact of PrEP on the Sex Lives of MSM at High Risk for HIV Infection
Congruence between Hypothetical Willingness to Use Pre-Exposure Prophylaxis (PrEP) and Eligibility
Men who have sex with men (MSM) are at high risk for acquiring HIV in Belgium. This study explores MSMs' hypothetical willingness to use pre-exposure prophylaxis (PrEP), assesses it against formal PrEP eligibility criteria, and identifies factors associated with incongruence between eligibility and willingness. We used data from an online survey of n = 1444 self-reported HIV-negative MSM. Participants were recruited through social media of MSM or…
International mobility, sexual behaviour and HIV-related characteristics of men who have sex with men residing in Belgium
The results of this study provide evidence for the role of international mobility and sexual behavior while travelling, in the spread of HIV and STI among MSM in Europe. Further, the findings underline the need for development of European cross-border HIV and STI interventions with coherent messages and prevention policies for MSM
Syndemic and Other Risk Factors for Unprotected Anal Intercourse Among an Online Sample of Belgian HIV Negative Men Who have Sex with Men

Evaluating Avahan’s design, implementation and impact
AVAHAN, the world's largest HIV prevention programme to date, needs no introduction to the international prevention community. Since its launch in 2003, AVAHAN and partners published over 100 papers in the peer reviewed literature in addition to the many presentations at AIDS conferences
The Need for Family Planning and Safe Abortion Services among Women Sex Workers Seeking STI Care in Cambodia
In Cambodia, clinics established for the prevention and management of sexually transmitted infections (STIs) in women sex workers do not address other reproductive health services. The aim of this study was to assess the need for more comprehensive sexual and reproductive health services for women sex workers in Cambodia. In January 2000, relevant documents were reviewed, interviews with key informants carried out and group interviews with women …

Sexually transmitted diseases
Chlamydiae represent a unique group of gram-negative organisms sharing a characteristic intracellular lifestyle. In common with other gram-negative bacteria their surface components, i.e. outer membrane constituents, play a major role in their interaction with their surroundings. Surface antigens appear to modulate the critical events of attachment, uptake, infectivity, toxicity and the host immune responses that contribute to immunity and pathog…
