HIV epidemic among key populations in Nigeria: results of the integrated biological and behavioural surveillance survey (IBBSS), 2020-2021.

Introduction: Nigeria has the fastest-growing HIV epidemic in West and Central Africa and key populations (KPs) bear a higher burden of HIV. This integrated biological and behavioural surveillance survey was conducted among female sex workers (FSW), men who have sex with men (MSM), people who inject drugs (PWID) and transgender (TG) populations to understand the changing dynamics of HIV to improve HIV prevention efforts in Nigeria.

Methods: Using a cross-sectional design, data were collected between October and November 2020 in 12 states, from randomly selected KP members using multistage probability sampling.

Prevalence and correlates of prenatal HIV testing among female sex workers in Nigeria.

Background: Female sex workers (FSWs) face a significant and persistent risk of contracting HIV. While evidence indicates high rates of pregnancy among FSWs in sub-Saharan Africa, studies on the coverage of HIV testing during pregnancy among them are sparse. The objective of this study was to estimate the prevalence of prenatal HIV testing and determine the associated factors among FSWs in Nigeria.

Advancing Programme Science approaches to understand gaps in HIV prevention programme coverage for key populations in 12 Nigerian states: findings from the 2020 Integrated Biological and Behavioural Surveillance Survey.

Introduction: Effective HIV prevention programme coverage is necessary to achieve Nigeria's goal of ending the epidemic by 2030. Recent evidence highlights gaps in service coverage and utilization across the country. The Effective Programme Coverage framework is a Programme Science tool to optimize a programme's population-level impact by examining gaps in programme coverage using data generated through programme-embedded research and learning.
