Background: Increased demand for healthcare services in countries experiencing high HIV disease burden and often coupled with a shortage of health workers, has necessitated task shifting from professional health workers to Lay Health Workers (LHWs) in order to improve healthcare delivery. Maternal and Child Health (MCH) services particularly benefit from task-shifting to LHWs or similar cadres. However, evidence on the roles and usefulness of LHWs in MCH service delivery in Sub-Saharan Africa (SSA) is not fully known., Objectives: To examine evidence of the roles and impact of lay health worker programmes focusing on Women Living with HIV (WLH) and their HIV-exposed infants (HEIs)., Methods: A scoping review approach based on Arksey and O'Malley's guiding principles was used to retrieve, review and analyse existing literature. We searched for articles published between January 2008 and July 2018 in seven (7) databases, including: MEDLINE, Embase, PsycINFO, Joanna Briggs, The Cochrane Library, EBM reviews and Web of Science. The critical constructs used for the literature search were "lay health worker", "community health worker", "peer mentor", "mentor mother," "Maternal and Child health worker", "HIV positive mothers", "HIV exposed infants" and PMTCT., Results: Thirty-three (33) full-text articles meeting the eligibility criteria were identified and included in the final analysis. Most (n = 13, 39.4%) of the included studies were conducted in South Africa and used a cluster RCT design (n = 13, 39.4%). The most commonly performed roles of LHWs in HIV specific MCH programmes included: community engagement and sensitisation, psychosocial support, linkage to care, encouraging women to bring their infants back for HIV testing and supporting default tracing. Community awareness on Mother to Child Transmission of HIV (MTCT), proper and consistent use of condoms, clinic attendance and timely HIV testing of HEIs, as well as retention in care for infected persons, have all improved because of LHW programmes., Conclusion: LHWs play significant roles in the management of WLH and their HEIs, improving MCH outcomes in the process. LHW interventions are beneficial in increasing access to PMTCT services and reducing MTCT of HIV, though their impact on improving adherence to ART remains scanty. Further research is needed to evaluate ART adherence in LHW interventions targeted at WLH. LHW programmes can be enhanced by increasing supportive supervision and remuneration of LHWs., Competing Interests: The authors have declared that no competing interests exist.

Whilst progress has been made, evidence of effective approaches to improve action on addressing the social and structural drivers of the HIV epidemic remains a priority, to meet the 2030 sustainable development agenda, and to achieve key HIV targets, including the 90-90-90 target and the Treatment as Prevention (TasP) intervention. With a focus on the public sector in South Africa, we critically reflect on the HIV mainstreaming approach, assessing its ability to augment multisectoral action on the response to HIV. We reflect on progress made in mainstreaming HIV in non-health sector departments, exploring factors that have enabled and hindered the process. We also highlight limitations in the adopted approach to mainstreaming HIV in non-health sector departments in South Africa; which currently promotes working in silos and does not encourage collaboration and partnerships. We propose a three-step approach to effective mainstreaming of HIV that will augment multisectoral action. The approach also contributes towards realising the sustainable development agenda of "leaving no one behind" and achieving the national and global targets on HIV that are embedded in collaborative efforts.

Antiretroviral treatment requires high levels of adherence to be effective. This qualitative study explores the reasons for poor adherence among 22 purposively selected poor urban participants in South Africa. Over a 4-month period in 2009, we prospectively investigated experiences of HIV diagnosis and treatment, adherence, and withdrawal from treatment. Patients with no stable food sources faced significant barriers in adhering to treatment regimens and staying sufficiently healthy to search for, obtain or retain a job. The narratives also identify the influence on adherence of self-esteem and social support, vulnerability generated by ill health, gendered conflict, social inequities amplified by HIV, and exhaustion due to the social burden of the epidemic. Multi-dimensional, inter-sectoral programs that tackle the social determinants of health, such as food insecurity, poverty, gendered inequities, and treatment adherence are more likely to be successful, than single interventions to support adherence.
