Adolescent girls and young women (AGYW) in sub-Saharan Africa experience delayed linkage to and poor retention in HIV care. Identifying and addressing specific barriers in HIV care programming is important to achieving the upgraded UNAIDS 95-95-95 targets and epidemic control. We examined these challenges among 103 HIV-positive AGYW in and out of HIV care in communities around Lake Victoria in western Kenya as part of a larger qualitative study to identify drivers of HIV testing and HIV care utilisation in key populations.

In 2017, Kenya became one of the first African countries to provide pre-exposure prophylaxis (PrEP) in its national HIV prevention plan. We sought to characterize factors associated with PrEP uptake and persistence among a cohort of women at risk of HIV infection during the early stages of PrEP scale-up in Kenya. HIV-negative women ≥18 years with ≥2 sexual partners in the past 4 weeks were recruited as part of an ongoing cluster randomized trial of an HIV self-testing intervention.

Oral fluid-based HIV self-testing (HIVST) has emerged as a promising approach to increasing HIV testing coverage, particularly among high-risk populations. Understanding the experiences of women using self-tests and offering them to their sexual partners (secondary distribution) is crucial for determining the potential of HIVST. Qualitative in-depth interviews were conducted among 32 women at high risk of HIV infection, including women who engage in transactional sex, who participated in a cluster randomised trial of a secondary distribution strategy in western Kenya.

Background: HIV self-testing can overcome barriers to HIV testing, but its potential as an HIV prevention strategy for women in sub-Saharan Africa has not been assessed. We examined whether sustained provision of self-tests to women promotes testing among sexual partners and reduces HIV incidence.

Methods: We conducted a pair-matched cluster-randomised trial in 66 community clusters in Siaya County, Kenya.

Introduction: Without significant increases in uptake of HIV testing among men, it will be difficult to reduce HIV incidence to disease elimination levels. Secondary distribution of HIV self-tests by women to their male partners is a promising approach for increasing male testing that is being implemented in several countries. Here, we examine male partner and couples testing outcomes and sexual decision making associated with this approach in a cluster randomized trial.
