Introduction High maternal HIV incidence contributes substantially to mother‐to‐child HIV transmission (MTCT) in some settings. Since 2006, HIV retesting during the third trimester and breastfeeding has been recommended by the World Health Organization in higher prevalence (≥5%) settings to reduce MTCT. However, many countries lack clarity on when and how often to retest pregnant and postpartum women to optimize resources and service delivery. We reviewed and characterized national guidelines on maternal retesting based on timing and frequency. Methods We identified 52 countries to represent variations in HIV prevalence, geography, and MTCT priority and searched available national MTCT, HIV testing and HIV treatment policies published between 2007 and 2017 for recommendations on retesting during pregnancy, labour/delivery and postpartum. Recommended retesting frequency and timing was extracted. Country HIV prevalence was classified as: very low (<1%), low (1% to 5%), intermediate (>5 to <15%) and high (≥15%). Women with unknown HIV status at delivery/postpartum were included in retesting guidelines. Results and discussion Overall, policies from 49 countries were identified; 51% from 2015 or later and most (n = 25) were from Africa. Four countries were high HIV prevalence, seven intermediate, sixteen low and twenty‐two very low. Most (n = 31) had guidance on universal voluntary opt‐out HIV testing at the first antenatal care (ANC) visit. Beyond the first ANC visit, the majority (78%, n = 38) had guidance on retesting; 22 recommended retesting all women with unknown/negative status, five only if unknown HIV status, three in pregnancy based on risk and eight combining these approaches. Retesting was universally recommended during pregnancy, labour/delivery, and postpartum for all high prevalence settings and four of seven intermediate prevalence settings. Five UNAIDS priority countries for EMTCT with low/very low HIV prevalence, but high/intermediate MTCT, had no guidance on retesting. Conclusions Retesting guidelines for pregnant and postpartum women were ubiquitous in high prevalence countries and defined in some intermediate prevalence countries, but absent in some low HIV prevalence countries with high MTCT. Countries may require additional guidance on how to optimize maternal HIV testing and whether to prioritize retesting efforts or discontinue universal retesting based on HIV incidence. Research is needed to assess country‐level guideline implementation and impact.

Introduction Uptake of early infant HIV diagnosis (EID) varies widely across sub‐Saharan African settings. We evaluated the potential clinical impact and cost‐effectiveness of universal maternal HIV screening at infant immunization visits, with referral to EID and maternal antiretroviral therapy (ART) initiation. Methods Using the CEPAC‐Pediatric model, we compared two strategies for infants born in 2017 in Côte d’Ivoire (CI), South Africa (SA), and Zimbabwe: (1) existing EID programmes offering six‐week nucleic acid testing (NAT) for infants with known HIV exposure (EID), and (2) EID plus universal maternal HIV screening at six‐week infant immunization visits, leading to referral for infant NAT and maternal ART initiation (screen‐and‐test). Model inputs included published Ivoirian/South African/Zimbabwean data: maternal HIV prevalence (4.8/30.8/16.1%), current uptake of EID (40/95/65%) and six‐week immunization attendance (99/74/94%). Referral rates for infant NAT and maternal ART initiation after screen‐and‐test were 80%. Costs included NAT ( $24/infant), maternal screening ($ 10/mother–infant pair), ART ( $5 to 31/month) and HIV care ($ 15 to 190/month). Model outcomes included mother‐to‐child transmission of HIV (MTCT) among HIV‐exposed infants, and life expectancy (LE) and mean lifetime per‐person costs for children with HIV (CWH) and all children born in 2017. We calculated incremental cost‐effectiveness ratios (ICERs) using discounted (3%/year) lifetime costs and LE for all children. We considered two cost‐effectiveness thresholds in each country: (1) the per‐capita GDP ( $1720/6380/2150) per year‐of‐life saved (YLS), and (2) the CEPAC‐generated ICER of offering 2 versus 1 lifetime ART regimens (e.g. offering second‐line ART; $ 520/500/580/YLS). Results With EID, projected six‐week MTCT was 9.3% (CI), 4.2% (SA) and 5.2% (Zimbabwe). Screen‐and‐test decreased total MTCT by 0.2% to 0.5%, improved LE by 2.0 to 3.5 years for CWH and 0.03 to 0.07 years for all children, and increased discounted costs by$17 to 22/child (all children). The ICER of screen‐and‐test compared to EID was $ 1340/YLS (CI),$650/YLS (SA) and $ 670/YLS (Zimbabwe), below the per‐capita GDP but above the ICER of 2 versus 1 lifetime ART regimens in all countries. Conclusions Universal maternal HIV screening at immunization visits with referral to EID and maternal ART initiation may reduce MTCT, improve paediatric LE, and be of comparable value to current HIV‐related interventions in high maternal HIV prevalence settings like SA and Zimbabwe.

Globally, nearly 38 million people are living with HIV, and 1.8 million are children. Each day approximately 5600 people acquire HIV. Since the emerging of HIV, 78 million people have been infected and close to 39 million have died. In developing countries, from all new HIV infections, half are because of mother-to-child transmission (MTCT). The aim of this study is to evaluate the effect of option B+ prevention of mother-to-child HIV transmission (PMTCT) and to develop strategies that contribute to eliminate MTCT in Addis Ababa, Ethiopia.
The study was conducted in three hospitals of Addis Ababa, Ethiopia, with a qualitative approach. Sixteen (16) in-depth interviews of HIV-positive mothers who had PMTCT follow-up and six focus group discussions with health professionals who work at a PMTCT unit were conducted. To analyse the data ATLAS.ti version 7 was used.
According to the findings of this study mother-to-child HIV transmission was associated with lack of HIV-discordant couples counselling guideline, lack of HIV disclosure strategy and counselling guidelines, unavailability of special PMTCT counselling guideline for HIV-positive commercial sex worker mothers and lack of HIV-free human breast milk (banked human breast milk) for PMTCT. Based on the study findings, a strategy that contributes to eliminate MTCT was developed.
Based on the research finding, the following four strategies were developed. Strategy 1: establish and use banked human breast milk for elimination of MTCT; Strategy 2: incorporate obligatory policy for discordant couple testing, counselling and disclosure with option B+ PMTCT; Strategy 3: develop disclosure policy and counselling guideline for PMTCT; and Strategy 4: formulate special PMTCT guideline for HIV-positive commercial sex worker mothers.

Introduction The new “90‐90‐90” UNAIDS agenda proposes that 90% of all people living with HIV will know their HIV status, 90% of all people with diagnosed HIV infection will receive sustained antiretroviral therapy and 90% of all people receiving antiretroviral therapy will have viral suppression by 2020. By focusing on children, the global community is in the unique position of realizing an end to the paediatric HIV epidemic. Discussion Despite vast scientific advances in the prevention and treatment of paediatric HIV infection over the last two decades, in 2014 there were an estimated 220,000 new paediatric infections attributed to mother‐to‐child HIV transmission (MTCT) and 150,000 HIV‐related paediatric deaths. Furthermore, adolescents remain at particularly high risk for acquisition of new HIV infections, and HIV/AIDS remains the second leading cause of death in this age group. Among the estimated 2.6 million children less than 15 years of age living with HIV infection, only 32% were receiving life‐saving antiretroviral treatment. After decades of languishing, good progress is now being made to prevent MTCT. Unfortunately, efforts to scale up HIV treatment services have been less robust for children and adolescents compared with adult populations. These discrepancies reflect substantial gaps in essential services and numerous missed opportunities to prevent HIV transmission and provide effective life‐saving antiretroviral treatment to children, adolescents and families. The road to an AIDS‐free generation will require bridging the gaps in HIV services and addressing the particular needs of children across the developmental spectrum from infancy through adolescence. To reach the ambitious new targets, innovations and service improvements will need to be rapidly escalated at each step along the prevention‐treatment cascade. Conclusions Charting a successful course to reach the 90‐90‐90 targets will require sustained political and financial commitment as well as the rapid implementation of a broad set of systematic improvements in service delivery. The prospect of a world where HIV no longer threatens the lives of infants, children and adolescents may finally be within reach.

Introduction The implementation of lifelong antiretroviral treatment (ART) for all pregnant women (Option B+) in Malawi has resulted in a significant increase in the number of HIV‐positive pregnant women initiating treatment. However, research has highlighted the challenge of retaining newly initiated women in care. This study explores barriers and facilitators that affect a woman's decision to initiate and to adhere to Option B+. Methods A total of 39 in‐depth interviews and 16 focus group discussions were conducted. Eligible women were ≥18 years old, living with HIV and either pregnant and receiving antenatal care from a study site or had delivered a child within the last 18 months, breastfed their child and received services at one of the study sites. Eligible women were identified by healthcare workers (HCWs) in the antenatal clinic and ART unit. Focus groups were also conducted with HCWs employed in these departments. Qualitative data were analyzed using Maxqda version 10 (VERBI Software, Berlin, Germany). Results The general perception towards the drug regimen used in Option B+ was positive; women reported fewer side effects and acknowledged the positive benefits of ART. Women felt hopeful about prolonging their life and having an HIV‐uninfected baby, yet grappled with the fact that ART is a lifelong commitment. Women and HCWs discussed challenges with the counselling services for prevention of mother‐to‐child HIV transmission under the new Option B+ guidelines, and many women struggled with initiating ART on the same day as learning their HIV status. Women wanted to discuss their circumstances with their husbands first, receive a CD4 count and obtain an HIV test at another facility to confirm their HIV status. HCWs expressed concern that women might just agree to take the drugs to please them. HCWs also discussed concerns around loss to follow‐up and drug resistance. Conclusions Although Option B+ has significantly increased the number of women initiating ART, there are still challenges that need to be addressed to strengthen initiation, adherence and retention in care. Strategies to strengthen the counselling services upon diagnosis need to be developed to improve same‐day initiation of ART and long‐term adherence.

Introduction Community‐based mentor mothers (cMMs) are women living with HIV who provide peer support to pregnant/postpartum women living with HIV (PWLWH) to enhance antiretroviral therapy (ART) adherence, retention in care and prevent perinatal transmission of HIV. The goal of this study was to explore the experiences, perceptions, mechanisms and health impact of cMMs on PWLWH in Kenya from the perspective of cMMs. Methods We conducted a prospective mixed‐methods study in southwestern Kenya in 2015–2018. In the qualitative phase, we completed in‐depth interviews with cMMs to explore their perceptions and experiences in supporting PWLWH. Transcripts were broad‐coded according to identified themes, then fine‐coded using an inductive approach. In the quantitative phase, we analysed medical record data from PWLWH who were randomized in the cMM intervention to examine the impact of cMM visits on optimal prevention of mother‐to‐child transmission (PMTCT). We used cluster‐adjusted generalized estimating equation models to examine relationships with a composite outcome (facility delivery, infant HIV testing, ART adherence and undetectable viral load at 6 weeks postpartum). Finally, qualitative and quantitative results were integrated. Results Convergence of findings from cMM interviews (n = 24) and PWLWH medical data (n = 589) revealed: (1) The cMM intervention was utilized and perceived as acceptable. PWLWH received, on average, 6.2 of 8 intended home visits through 6 weeks postpartum. (2) The cMMs reported serving as role models and confidantes, supporting PWLWH's acceptance of their HIV status, providing assurances about PMTCT and assisting with male partner disclosure and communication. cMMs also described benefits for themselves, including empowerment and increased income. (3) The cMM visits supported PWLWH's completion of PMTCT steps. Having ≥4 cMM home visits up to 6 weeks postpartum, as compared to <4 visits, was associated with higher likelihood of an optimal PMTCT composite outcome (adjusted relative risk 1.42, p = 0.044). Conclusions We found that peer support from cMMs during pregnancy through 6 weeks postpartum was associated with improved uptake of critical PMTCT services and health behaviours and was perceived as beneficial for cMMs themselves. CMM support of PWLWH may be valuable for other low‐resource settings to improve engagement with lifelong ART and HIV services among PWLWH.

Aim To understand HIV stigma and self‐efficacy of labour and delivery (L&D) providers in caring for women living with HIV (WLHIV). Design Cross‐sectional descriptive mixed methods. Methods Data were collected in six primary healthcare facilities in the Kilimanjaro region, Tanzania between February and November 2022. We conducted eight focus groups with L&D providers (n = 36) and nurse‐midwifery students (n = 12). We conducted surveys with 60 L&D providers assessing HIV stigma (fear of acquisition, extra precautions and attitudes) and self‐efficacy in caring for WLHIV. Qualitative findings were complemented by survey data to provide a comprehensive understanding of providers' attitudes and experiences. Results Providers expressed fear of HIV acquisition when caring for WLHIV. Almost all providers noted that they used extra precautions with WLHIV; 97% used double gloves and 39% avoided touching WLHIV with bare hands, even when there were no bodily fluids. Most providers had positive attitudes towards WLHIV. Almost all rejected the idea that HIV was a punishment for bad behaviour, but 44% thought their patients might not be careful about infecting others. Qualitative data suggested providers worried that patients' reluctance to disclose their HIV status could raise the risk of occupational exposure. Provider self‐efficacy in normal birth was lower when caring for a woman with HIV compared with care for women who are HIV‐negative but did not differ significantly in other situations. Conclusion This study showed that providers had generally low‐stigmatising attitudes towards people living with HIV but feared occupational exposure, leading to avoidance of necessary patient contact. Training on clinical and interpersonal skills, coupled with evidence‐based care for women with HIV during childbirth, could benefit both providers and patients. Reporting Method The study is reported following the Good Reporting of a Mixed‐Methods Study (GRAMMS) checklist. Patient or Public Contribution Patients and the public were not involved in this research.

Mother-to-child transmission (MTCT) of human immune deficiency virus (HIV) is the infection of baby by HIV that originated from an HIV-positive mother during pregnancy and breast feeding. Without intervention, the transmission rate of HIV ranges from 15-45%, which can be reduced to below 5% with effective intervention. In Ethiopia, the final mother-to-child transmission rate was 15% in 2016, which was much higher than the target of the country to reduce transmission to lower than 5% by 2020. The study aims to identify determinants of transmission of HIV from mother to child in the West Shewa Zone.
An unmatched case-control study, among children less than 5 years who tested HIV positive and negative, at the end of PMTC follow-up, N=96 (24 cases, 72 controls) was conducted during June to August 2019, focusing on PCR done during the last 2 years (June 2017 to July 2019), in public hospitals. Data were collected using a structured questionnaire and data abstraction forms from mothers of exposed infants, medical records of mothers and children.
The majority of cases (17, 70.8%) were not included in the option B+ program, but only 11.1% of controls were not included. Home delivery (adjusted odds ratio (AOR)=6.047, confidence interval (CI)=1.549-29.230), non-inclusion into option B+ (AOR=18.0, 95% CI=5.0-68.1), and partner non-involvement to HIV care (AOR=7.3, 95% CI=1.14-37.459) had higher odds of transmitting HIV, while a mother-to-mother support program decreases the chance of transmission by 86.5% (AOR=0.135, 95% CI=0.11-0.396) when compared to their counterparts.
Mother-to-mother support programs have a protective effect, while non-inclusion to option B+, partner non-involvement in HIV care, home delivery, and poor antenatal care (ANC) practices were determinant factors of HIV transmission from mother to child.

Background
WHO recommends that HIV infected women receive antiretroviral therapy (ART) minimally during pregnancy and breastfeeding (“Option B”), or ideally throughout their lives regardless of clinical stage (“Option B+”) (Coovadia et al., Lancet 379:221–228, 2012). Although these recommendations were based on clinical trials demonstrating the efficacy of ART during pregnancy and breastfeeding, the population-level effectiveness of Option B+ is unknown, as are retention on ART beyond the immediate post-partum period, and the relative impact and cost-effectiveness of Option B+ compared to Option A (Centers for Disease Control and Prevention, Morb Mortal Wkly Rep 62:148–151, 2013; Ahmed et al., Curr Opin HIV AIDS 8:473–488, 2013). To address these issues, we conducted an impact evaluation of Zimbabwe’s prevention of mother to child transmission programme conducted between 2011 and 2018 using serial, community-based cross-sectional serosurveys, which spanned changes in WHO recommendations. Here we describe the rationale for the design and analysis.
Methods/design
Our method is to survey mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. We collect questionnaires, blood samples from mothers and babies for HIV antibody and viral load testing, and verbal autopsies for deceased mothers/babies. Using this approach, we collected data from two previous time points: 2012 (pre-Option A standard of care), 2014 (post-Option A / pre-Option B+) and will collect a third round of data in 2017–18 (post Option B+ implementation) to monitor population-level trends in mother-to-child transmission of HIV (MTCT) and HIV-free infant survival. In addition, we will collect detailed information on facility level factors that may influence service delivery and costs.
Discussion
Although the efficacy of antiretroviral therapy (ART) during pregnancy and breastfeeding for prevention of mother-to-child transmission of HIV (PMTCT) has been well-documented in randomized trials, little evidence exists on the population-level impact and cost-effectiveness of Option B+ or the influence of the facility on implementation (Siegfried et al., Cochrane Libr 7:CD003510, 2017). This study will provide essential data on these gaps and will provide estimates on retention in care among Option B+ clients after the breastfeeding period.

Introduction With the rapid scale‐up of antiretroviral treatment (ART) in the “Treat All” era, there has been increasing emphasis on using differentiated models of HIV service delivery. The gaps within the clinical cascade for mothers and their infants suggest that current service delivery models are not meeting families' needs and prompt re‐consideration of how services are provided. This article will explore considerations for differentiated care and encourage the ongoing increase of ART coverage through innovative strategies while also addressing the unique needs of mothers and infants. Discussion Service delivery models should recognize that the timing of the mother's HIV diagnosis is a critical aspect of determining eligibility. Women newly diagnosed with HIV require a more intensive approach so that adequate counselling and monitoring of ART initiation and response can be provided. Women already on ART with evidence of virologic failure are also at high risk of transmitting HIV to their infants and require close follow‐up. However, women stable on ART with a suppressed viral load before conception have a very low likelihood of HIV transmission and thus are strong candidates for multi‐month ART dispensing, community‐based distribution of ART, adherence clubs, community adherence support groups and longer intervals between clinical visits. A number of other factors should be considered when defining eligibility of mothers and infants for differentiated care, including location of services, viral load monitoring and duration on ART. To provide differentiated care that is client‐centred and driven while encompassing a family‐based approach, it will be critical to engage mothers, families and communities in models that will optimize client satisfaction, retention in care and quality of services. Conclusions Differentiated care for mothers and infants represents an opportunity to provide client‐centred care that reduces the burden on clients and health systems while improving the quality and uptake of services for families. However, with decreasing funding, stable HIV incidence, and aspirations for sustainability, it is critical to consider efficient, customized and cost‐effective models of care for these populations as we aspire to eliminate mother‐to‐child transmission of HIV.
