Supplement: Population mobility - Challenges for universal HIV testing and treatment

Guest Editors: Carol S Camlin, Susan Cassels, Janet Seeley

Several meta-analyses and systematic reviews of the literature examining factors associated with care entry, engagement and retention show that optimal lifelong engagement in HIV care can be threatened by a range of factors at the individual, social, and structural levels. Mobility affects many of the factors found to contribute to delayed entry or lapses in care, including psychological factors (e.g. seeking care away from home because of stigma), clinic characteristics (e.g. waiting times) and structural barriers such as distance to clinic and transportation costs. Yet the direct impact of mobility, and the pathways for this impact, have not been examined in depth.

Better measures and methods are needed to understand how mobility affects the ability of individuals to successfully navigate the HIV care cascade. This is especially urgent for sub-Saharan Africa, where levels of mobility are high and forms of mobility are complex and dynamic. The effects of mobility on initiatives designed to extend the reach of primary HIV prevention interventions in these settings are, to date, unknown— a glaring gap in the literature. The articles in this supplement of the Journal of the International AIDS Society focus on crucial questions regarding the forms and dimensions of mobility and the impact on HIV prevention and care initiatives—particularly in Southern and Eastern Africa, but also in the ‘receiving’ nations in the global north of sub-Saharan African migrants.

To understand the uptake of HIV services by adolescent women, the authors conducted a retrospective analysis of patient-level data (2011–2013) on services for antenatal care (ANC) and prevention of mother-to-child transmission (PMTCT) in 36 facilities in 5 districts in Zimbabwe.

Female sex workers (FSW) in sub-Saharan Africa have a higher prevalence of HIV than other women of reproductive age. Social, legal, and structural barriers influence their access to care. Little is known about the HIV diagnosis and care cascade in most countries in southern Africa.

Background: The recent scale-up of prevention of mother-to-child transmission of HIV (PMTCT) services has rapidly accelerated antiretroviral therapy (ART) uptake among pregnant and postpartum women in sub-Saharan Africa.

This study aimed to evaluate the impact of clinic-based prevention of mother-to-child transmission (PMTCT) community support by trained lay health workers in addition to standard clinical care on PMTCT infant outcomes.
