'I take the drugs… to make the sickness to move out of me': key populations' and service provider perspectives about facilitators and barriers to ART adherence and retention in care in Nigeria.

Background: Adherence to antiretroviral therapy (ART) has individual and public health benefits and is critical to improving life expectancy, achieving viral suppression, and reducing the risk of HIV transmission. This qualitative study explored the experience of receiving care as well as perceived facilitators and barriers of treatment initiation, retention in ART care, and adherence to treatment.

Methods: In-depth interviews were conducted among 28 men who have sex with men (MSM) and female sex workers (FSWs) receiving ART services in Lagos and Benue states.

Rising HIV prevalence among men who have sex with men in Nigeria: a trend analysis.

Background: Men who have sex with men (MSM) are conservatively estimated to be less than 1% of the Nigerian population yet nationally account for about 20% of new HIV infection. We estimated the trend in HIV prevalence and determined correlates of HIV infection among MSM.

Methods: This study used data from respondent-driven sampling in three rounds of integrated biological and behavioral surveillance survey (2007, 2010 and 2014) and covered three states in 2007, six states in 2010 and eight states in 2014.
