    Acceptability of pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) in Benin : a qualitative study
    (Taylor & Francis, 2019-05-25) Gning, Ndeye Ndiagna; Guédou, Fernand Aimé; Diabate, Souleymane; Hessou, Septime; Batona, Georges; Béhanzin, Luc; Alary, Michel; Ahouada, Carin; Zannou, Marcel D.
    In Benin, consistent condom use among men who have sex with men (MSM) is relatively low and providing them with Pre-exposure prophylaxis (PrEP) could be of great relevance. We aimed to describe PrEP knowledge and intention to use it; identify key facilitators and barriers to PrEP; and describe the perceived impact of PrEP on unsafe sexual behavior. MSM, 18 years or older, HIV-negative or of unknown status, were enrolled in five cities of Benin. Intention to use PrEP was assessed through five focus groups (FG). Data were analyzed using manual thematic sorting. Thirty MSM (six per city) participated in the FG. Mean age (standard deviation) was 27.1 (5.0) years. All participants expressed the intention to use PrEP if made available. Facilitators of PrEP use were: availability of medication, safety, absence of constraints as well as freedom to have multiple sex partners and sex with HIV-positive friends. Barriers were: complex procedures for obtaining medication, size and taste of medication, cost of medication, poor PrEP awareness.. Eighteen men admitted that PrEP could lead to decrease in or even abandonment of condom use. In conclusion, MSM showed openness to use PrEP if available, although they recognized that it could lead to risk compensation.

    HIV prevention and treatment cascades among female sex workers in Benin, West Africa
    (J.B. Lippincott, 2021-02-23) Guédou, Fernand Aimé; Diabate, Souleymane; Béhanzin, Luc; Kêkê, René Kpèmahouton; Morin, Laurianne; Bushman, Lane; Alary, Michel; Anderson, Peter L.; Gangbo, Flore; Nagot, Nicolas
    Background & Objectives Benin has a long-standing history of HIV prevention programs aimed at female sex workers (FSWs). We used data from a national survey among FSWs (2017) to assess the prevention and care cascades in this population. Methods FSWs were recruited through cluster sampling of sex work sites. A questionnaire was administered, and HIV tested. HIV-positive participants were asked to provide dried-blood spots (DBS), tested for ARV and viral load. We assessed two prevention cascades (HIV testing and safer sex) and the treatment cascade, using a combination of self-reported and biological variables. Results Mean age of the 1086 FSWs was 30 years. Half of them were Beninese and two-thirds had a primary school education level or less. Almost all FSWs had ever heard of HIV/AIDS. 79.1% had ever been tested, and 84.1% of the latter had been tested in the last year. In the previous six months, 90.1% were exposed to prevention messages. Women exposed to any HIV prevention message reported a higher level of consistent condom use in the last month (69.0%) than those who were not (48.5%, p<0.0001). HIV prevalence was 7.7%. Among HIV-positive women, 60.6% knew their status; among those, 90.5% were on ARV and 81.8% of them had a suppressed viral load. Conclusions Despite long-standing HIV prevention programs for FSWs, the prevention indicators were often low. Linkage to care was good, viral suppression was sub-optimal, but knowledge of HIV-positive status was low. Exposing women to prevention messages is necessary, as to increase HIV testing.
