"So that's why I found PrEP to be safest way to protect yourself": exploring IPV experiences and impact on HIV prevention among pregnant and postpartum women in Cape Town, South Africa. BMC Public Health 2024; 24:481. [PMID: 38360616 PMCID: PMC10870618 DOI: 10.1186/s12889-024-17871-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Accepted: 01/24/2024] [Indexed: 02/17/2024] Open
Abstract
Intimate partner violence (IPV) occurs at alarmingly high rates towards pregnant women in South Africa. Experiences of emotional, physical, and sexual IPV in pregnancy can adversely impact the health and safety of mother and fetus. Furthermore, IPV is associated with increased risk of HIV, exacerbating the public health impact of violence among pregnant women in this HIV endemic setting. In-depth understanding of cultural and contextual drivers of experiences of IPV is a critical precursor to development of interventions effectively addressing this issue among pregnant women in South Africa. The present study examines factors contributing to IPV among pregnant women to identify potential points of intervention. We conducted twenty in-depth interviews with postpartum women who used oral pre-exposure prophylaxis (PrEP) in pregnancy and reported recent experiences of IPV and/or ongoing alcohol use in a township near Cape Town, South Africa that experiences a heavy burden of both HIV and IPV. Interpretive thematic analysis was used. Several patterns of IPV during pregnancy were identified and violence was frequently described as co-occurring with male partner alcohol use. A majority of women referenced oral PrEP as their preferred method for HIV prevention, highlighting the agency and discretion it provided as beneficial attributes for women experiencing IPV. Fear of judgement from peers for remaining with an abusive partner and a lack of clear community messaging around IPV were identified as barriers to disclosure and support-seeking. Addressing the lack of social support received by women experiencing IPV during pregnancy in South Africa is essential to comprehensive IPV programming.

Abstract
Pregnant women in sub-Saharan Africa have high rates of maternal morbidity. There is interest in the impact of the vaginal microbiome on maternal health, including HIV and sexually transmitted infection (STI) acquisition. We characterized the vaginal microbiota of South African women ≥ 18 years with and without HIV in a longitudinal cohort over two visits during pregnancy and one visit postpartum. At each visit, we obtained HIV testing and self-collected vaginal swabs for point-of-care testing for STIs and microbiota sequencing. We categorized microbial communities and evaluated changes over pregnancy and associations with HIV status and STI diagnosis. Across 242 women (mean age 29, 44% living with HIV, 33% diagnosed with STIs), we identified four main community state types (CSTs): two lactobacillus-dominant CSTs (dominated by Lactobacillus crispatus and Lactobacillus iners respectively) and two diverse, non-lactobacillus-dominant CSTs (one dominated by Gardnerella vaginalis and one by diverse facultative anaerobes). From the first antenatal visit to the third trimester (24-36 weeks gestation), 60% of women in the Gardnerella-dominant CST shifted to lactobacillus-dominant CSTs. From the third trimester to postpartum (mean 17 days post-delivery), 80% of women in lactobacillus-dominant CSTs shifted to non-lactobacillus-dominant CSTs with a large proportion in the facultative anaerobe-dominant CST. Microbial composition differed by STI diagnosis (PERMANOVA R2 = 0.002, p = 0.004), and women diagnosed with an STI were more likely to be categorized as L. iners-dominant or Gardnerella-dominant CSTs. Overall, we found a shift toward lactobacillus dominance during pregnancy and the emergence of a distinct, highly diverse anaerobe-dominant microbiota profile in the postpartum period.

Abstract
Background Although HIV vertical transmission (VT) has declined significantly in sub-Saharan Africa, incident HIV infection in pregnant and postpartum women is estimated to account for roughly one-third of VT. Oral pre-exposure prophylaxis (PrEP) for pregnant and breastfeeding women (PBFW) is part of the recommended guidelines in South Africa since 2021; however, integration of PrEP services within antenatal (ANC) and postnatal care (PNC) remains limited. Methods Between March 2022 and September 2023, we evaluated the acceptability, feasibility and sustainability of integrating PrEP for PBFW in high-HIV prevalence clinics after training and mentoring health care providers (HCP). We used the Reach Effectiveness-Adoption Implementation Maintenance (RE-AIM) framework to evaluate the intervention. Acceptability and maintenance were defined as the proportion of PBFW without HIV who initiated PrEP and the proportion of women continuing PrEP at 3 months in ANC or PNC services. Feasibility was defined as the proportion of trained HCPs (HIV lay counsellors and nurses/ midwives) who provided PrEP according to national guidelines, measured through post-training surveys and in-service assessments. Sustainability was defined as number of facilities and providers that continued to provide PrEP for PBFW past the mentoring period. Results In 8 facilities providing ANC and PNC, we trained 224 HCP (127 nurses and 37 counsellors). Of those, we mentored 60 nurses, midwives and HIV counsellors working with PBFW, with 72% of nurse/midwives and 65% of counsellors scoring over 8/10 on the final mentoring assessment Overall, 12% (1493/12,614) of HIV-negative pregnant women started PrEP and 41% of those continued PrEP at 3-months. Among the HIV-negative breastfeeding women in postnatal care, 179/1315 (14%) initiated PrEP and 25% continued PrEP at 3-months. All 8 facilities continued providing PrEP 3-months after handover of the clinics. Conclusion Integration of PrEP services in ANC and services for breastfeeding women was feasible, acceptable and sustainable. Acceptability and PrEP continuation showed improvement over time. Barriers to the PrEP integration were observed including the lack of regular HIV testing of breastfeeding mothers and need for ART-trained nurses to prescribe PrEP. Enablers included motivated and dedicated staff.

Evaluating the use of oral pre-exposure prophylaxis among pregnant and postpartum adolescent girls and young women in Cape Town, South Africa. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 5:1224474.

Abstract
Background Adolescent girls and young women (AGYW) in South Africa are at a higher risk of acquiring HIV. Despite the increasing availability of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention, knowledge on PrEP use during pregnancy and postpartum periods at antenatal care (ANC) facilities remains inadequate. Methods Data from HIV-uninfected pregnant women in Cape Town, South Africa, were used in this study. These women aged 16-24 years were enrolled in the PrEP in pregnancy and postpartum (PrEP-PP) cohort study during their first ANC visit. Using the PrEP cascade framework, the outcomes of the study were PrEP initiation (prescribed tenofovir disoproxil fumarate and emtricitabine at baseline), continuation (returned for prescription), and persistence [quantifiable tenofovir diphosphate (TFV-DP) in dried blood samples]. The two primary exposures of this study were risk perception for HIV and baseline HIV risk score (0-5), which comprised condomless sex, more than one sexual partner, partner living with HIV or with unknown serostatus, laboratory-confirmed sexually transmitted infections (STIs), and hazardous alcohol use before pregnancy (Alcohol Use Disorders Identification Test for Consumption score ≥ 3). Logistic regression was used to examine the association between HIV risk and PrEP, adjusting for a priori confounders. Results A total of 486 pregnant women were included in the study, of which 16% were "adolescents" (aged 16-18 years) and 84% were "young women" (aged 19-24 years). The adolescents initiated ANC later than the young women [median = 28 weeks (20-34) vs. 23 weeks (16-34), p = 0.04]. Approximately 41% of the AGYW were diagnosed with sexually transmitted infection at baseline. Overall, 83% of the AGYW initiated PrEP use during their first ANC. The percentage of PrEP continuation was 63% at 1 month, 54% at 3 months, and 39% at 6 months. Approximately 27% consistently continued PrEP use through 6 months, while 6% stopped and restarted on PrEP use at 6 months. With a higher risk score of HIV (≥2 vs. ≤1), the AGYW showed higher odds of PrEP continuation [adjusted odds ratio: 1.85 (95% CI: 1.12-3.03)] through 6 months, adjusting for potential confounders. Undergoing the postpartum period (vs. pregnant) and having lower sexual risk factors were found to be the barriers to PrEP continuation. TFV-DP concentration levels were detected among 49% of the AGYW, and 6% of these women had daily adherence to PrEP at 3 months. Conclusions AGYW were found to have high oral PrEP initiation, but just over one-third of these women continued PrEP use through 6 months. Pregnant AGYW who had a higher risk of acquiring HIV (due to condomless sex, frequent sex, and STIs) were more likely to continue on PrEP use through the postpartum period. Pregnant and postpartum AGYW require counseling and other types of support, such as community delivery and peer support to improve their effective PrEP use through the postpartum period. Clinical Trial Number ClinicalTrials.gov, NCT03826199.

Abstract
Modern antiretroviral therapy safely, potently, and durably suppresses human immunodeficiency virus (HIV) that, if left untreated, predictably causes acquired immunodeficiency syndrome (AIDS), which has been responsible for tens of millions of deaths globally since it was described in 1981. In one of the most extraordinary medical success stories in modern times, a combination of pioneering basic science, innovative drug development, and ambitious public health programming resulted in access to lifesaving, safe drugs, taken as an oral tablet daily, for most of the world. However, substantial challenges remain in the fields of prevention, timely access to diagnosis, and treatment, especially in pediatric and adolescent patients. As HIV-positive adults age, treating their comorbidities will require understanding the course of different chronic diseases complicated by HIV-related and antiretroviral toxicities and finding potential treatments. Finally, new long-acting antiretrovirals on the horizon promise exciting new options in both the prevention and treatment fields.

Abstract
This study examines baseline associations between alcohol use and HIV sexual risk among a cohort of HIV-uninfected pregnant women (n = 1201) residing in a high HIV burdened community in Cape Town, South Africa. Alcohol use was measured using a modified version of the Alcohol Use Disorder Identification Test (AUDIT). HIV sexual risk was measured through a composite variable of four risk factors: diagnosis with a STI, self-report of > 1 recent sex partners, partner HIV serostatus (unknown or HIV+) and condomless sex at last sex. Any past year alcohol use prior to pregnancy was reported by half of participants (50%); 6.0% reported alcohol use during pregnancy. Alcohol use prior to pregnancy was associated with increased odds of being at high risk of HIV (aOR = 1.33, 95% CI 1.05-1.68, for 2 risks and aOR = 1.47, 95% CI 0.95-2.27 for 3 risks). In addition to reducing alcohol use, several other strategies to address HIV sexual risk were identified. Evidence-based interventions to address alcohol use and other HIV sexual risk behaviors during pregnancy in South Africa are desperately needed. Qualitative work exploring individual and community level drivers of alcohol use among pregnant and breastfeeding women in this setting could support development of a culturally tailored intervention to address these issues in this population.

Prevalence of undiagnosed HIV among children in South Africa, Côte d'Ivoire and Zimbabwe: a model-based analysis to inform paediatric HIV screening programmes. J Int AIDS Soc 2022; 25:e26045. [PMID: 36519674 PMCID: PMC9753158 DOI: 10.1002/jia2.26045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 11/22/2022] [Indexed: 12/23/2022] Open
Abstract
INTRODUCTION To improve the diagnosis and survival of children living with HIV (CLWH), the World Health Organization recommends testing approaches beyond traditional infant HIV testing programmes. Information about undiagnosed HIV prevalence among children of varying ages in the general population is needed to guide innovative national/subnational case-finding and testing approaches. METHODS We used the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-Pediatric model to estimate the prevalence of undiagnosed HIV in 2-, 5- and 10-year-old children in South Africa, Côte d'Ivoire and Zimbabwe in 2018. We simulated cohorts of children born in 2008 (10-year-olds), 2013 (5-year-olds) and 2016 (2-year-olds). Country-/year-specific inputs for pregnant/breastfeeding women included: HIV prevalence (4.2-32.3%), HIV incidence (0.03-0.24%/month), knowledge of HIV status (27-89%) and antiretroviral drug coverage (36-95%). Paediatric inputs included early infant testing coverage (6-95%) and breastfeeding duration (0-20 months). We projected the proportion of surviving CLWH in whom HIV remained undiagnosed and the undiagnosed HIV prevalence among surviving children of each age in the general population. For children born in 2016, we projected survival and diagnosis of all CLWH through 2026. We conducted sensitivity analyses on model parameters. RESULTS In 2018, the projected proportion of surviving CLWH whose HIV remained undiagnosed in South Africa/Côte d'Ivoire/Zimbabwe was 44.2%/55.8%/52.9% among 2-year-old CLWH; 29.0%/37.8%/33.2% among 5-year-old CLWH; and 18.3%/25.4%/23.1% among 10-year-old CLWH. Projected general population undiagnosed HIV prevalence in South Africa/Côte d'Ivoire/Zimbabwe was 0.44%/0.32%/0.68% among 2-year-olds; 0.25%/0.17%/0.41% among 5-year-olds; and 0.24%/0.14%/0.38% among 10-year-olds. Among all CLWH born in 2016, 50-54% were projected to die without HIV diagnosis (and subsequently without treatment) within 10 years after birth; 80-85% of these deaths occurred in the first 2 years. CONCLUSIONS Projected population-level undiagnosed HIV prevalence is low and sharply decreases after age 2, with more CLWH dying than being diagnosed. Despite low undiagnosed prevalence in the general population of older children, we project that a large proportion of CLWH remain undiagnosed, suggesting that innovative strategies targeting untested children of all ages outside of health facility settings should be prioritized. Programmes could consider routine testing of the general population of children below 2 in all settings and children of all ages in high-prevalence settings.

The importance of assessing and addressing mental health barriers to PrEP use during pregnancy and postpartum in sub-Saharan Africa: state of the science and research priorities. J Int AIDS Soc 2022; 25:e26026. [PMID: 36251124 PMCID: PMC9575939 DOI: 10.1002/jia2.26026] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 09/28/2022] [Indexed: 11/06/2022] Open
Abstract
Introduction Pregnant and postpartum women (PPW) in sub‐Saharan Africa are at disproportionately high risk of HIV infection compared to non‐pregnant women. When used consistently, pre‐exposure prophylaxis (PrEP) can prevent HIV acquisition and transmission to the foetus or infant during these critical periods. Recent studies have demonstrated associations between mental health challenges (e.g. depression and traumatic stress associated with intimate partner violence) and decreased PrEP adherence and persistence, particularly among adolescents, younger women and women in the postpartum period. However, mental health is not currently a major focus of PrEP implementation research and programme planning for PPW. Discussion PrEP implementation programmes for PPW need to assess and address mental health barriers to consistent PrEP use to ensure effectiveness and sustainability in routine care. We highlight three key research priorities that will support PrEP adherence and persistence: (1) include mental health screening tools in PrEP implementation research with PPW, both to assess the feasibility of integrating these tools into routine antenatal and postpartum care and to ensure that limited resources are directed towards women whose symptoms may interfere most with PrEP use; (2) identify cross‐cutting, transdiagnostic psychological mechanisms that affect consistent PrEP use during these periods and can realistically be targeted with intervention in resource‐limited settings; and (3) develop/adapt and test interventions that target those underlying mechanisms, leveraging strategies from existing interventions that have successfully mitigated mental health barriers to antiretroviral therapy use among people with HIV. Conclusions For PPW, implementation of PrEP should be guided by a robust understanding of the unique psychological difficulties that may act as barriers to uptake, adherence and persistence (i.e. sustained adherence over time). We strongly encourage PrEP implementation research in PPW to incorporate validated mental health screening tools and ultimately treatment in routine antenatal and postnatal care, and we stress the potential public health benefits of identifying women who face mental health barriers to PrEP use.

Abstract
Introduction Pre‐exposure prophylaxis (PrEP) is a safe and effective prevention strategy to reduce women's risk of HIV in pregnancy and postpartum. Effective PrEP protection requires daily PrEP adherence, but little is known about maternal PrEP continuation and factors that influence PrEP use. Methods The PrEP in pregnancy and postpartum (PrEP‐PP) study enrolled consenting pregnant, HIV‐negative women at first antenatal care (ANC) visit with follow‐up through 12 months postpartum. Eligible and consenting women and girls ≥16 years received HIV prevention counselling and were offered PrEP. Interviewers collected socio‐demographic and behavioural data from participants at each visit. We analysed the proportion of women who initiated PrEP and the proportion who continued PrEP after 3 months with associated correlates by estimating the prevalence ratio adjusting for a priori confounders. Results Between August 2019 and October 2021, we enrolled 1201 pregnant women (median gestation 21 weeks; age 26 years); 84% of women initiated PrEP at their first ANC visit (n = 1014); 55% were married or cohabiting. Overall, 66% of women on PrEP returned for a repeat prescription at 1 month; 58% returned at 3 months (n = 493 of 844). Almost one‐half of women on PrEP reported a side effect at 1 month, mostly nausea/vomiting. Women on PrEP in the first and second trimesters had higher odds of reporting side effects (aOR 2.61; 95% CI 1.17–5.84) versus postpartum women. Women who reported side effects continued with PrEP less than those who did not report side effects (aPR = 0.87; 95% CI 0.77–0.97). Women with ≥1 previous pregnancy (aPR = 0.76; 95% CI 0.57–1.01) or were postpartum (aPR 0.85; 95% CI 0.75–0.97) were less likely to continue PrEP compared to women who were primigravid or pregnant. Women who reported having an HIV+ partner (aPR = 1.45; 95% CI 1.13–1.85) or high HIV risk perception (aPR = 1.20, 95% CI = 1.01–1.41) were more likely to continue on PrEP than those who had HIV‐negative partners or low risk perception. Conclusions PrEP initiation and early continuation were high in this setting, compared to other studies in women. Being postpartum and experiencing side effects were associated with lower PrEP continuation, presenting opportunities for counselling on early transient side effects. Interventions for postpartum women on PrEP are needed.

Evidence from panel data analysis. BMC Infect Dis 2022; 22:134. [PMID: 35135474 PMCID: PMC8822759 DOI: 10.1186/s12879-022-07119-6] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Accepted: 02/02/2022] [Indexed: 11/10/2022] Open
Abstract
Background Antiretroviral therapy for pregnant women infected with HIV has evolved significantly over time, from single dosage antiretroviral and zidovudine alone to lifelong combination of antiretroviral therapy, but the effect of the intervention on population-level child HIV infection has not been well studied in sub-Saharan Africa. Therefore, this study aimed to establish the trend and effect of ART coverage during pregnancy on mother-to-child HIV transmission in sub-Saharan Africa from 2010 to 2019. Methods Country-level longitudinal ecological study design was used. Forty-one sub-Saharan Africa countries were included using publicly available data from the United Nations Programme on HIV/AIDS, World Health Organization, and World Bank. We created a panel dataset of 410 observations for this study from the years 2010–2019. Linear fixed effects dummy variable regression models were conducted to measure the effect of ART coverage during pregnancy on MTCT rate. Regression coefficients with their 95% confidence intervals (CIs) were estimated for each variable from the fixed effects model. Results ART coverage during pregnancy increased from 32.98 to 69.46% between 2010 and 2019. Over the same period, the rate of HIV transmission from mother to child reduced from 27.18 to 16.90% in sub-Saharan Africa. A subgroup analysis found that in southern Africa and upper-middle-income groups, higher ART coverage, and lower MTCT rates were recorded. The fixed-effects model result showed that ART coverage during pregnancy (β = − 0.18, 95% CI − 0.19–− 0.16) (p < 0.001) and log-transformed HIV incidence-to-prevalence ratio (β = 5.41, 95% CI 2.18–8.65) (p < 0.001) were significantly associated with mother-to-child HIV transmission rate. Conclusions ART coverage for HIV positive pregnant women and HIV incidence-to-prevalence ratio were significantly associated with MTCT rate in sub-Saharan Africa. Based on these findings we suggest countries scale up ART coverage by implementing varieties of proven strategies and control the HIV epidemic to achieve the global target of eliminating MTCT of HIV in the region.

Abstract
Introduction A recent sero‐discordant couple study showed an elevated risk of HIV‐acquisition during the pregnancy/postpartum period per‐condomless‐coital‐act. This, along with previous studies, has led to concern over possible increased risk of mother‐to‐child (vertical) transmission, due to the initial high viral load in the first months after seroconversion, in a time when the woman and health services may be unaware of her status. This study looks at whether behavioural differences during the pregnant/postpartum period could reduce the impact of elevated risk of HIV acquisition per‐condomless‐coital‐act at the population level. Methods We used data from 60 demographic and health surveys from 32 sub‐Saharan African countries. Using the HIV status of couples, we estimated differences in serodiscordancy between HIV‐negative women who were pregnant/postpartum compared to those who were not pregnant/postpartum. We compare the risk of sexual activity over the pregnant/postpartum period to those not pregnant/postpartum. Using these risks of serodiscordancy and sexual activity along with estimates of increased HIV risk in the pregnancy/postpartum period per‐condomless‐coital‐act, we estimated a population‐level risk of HIV acquisition and acute infection, during pregnancy/postpartum compared to those not pregnant/postpartum. Results Sexual activity during pregnancy/postpartum varies considerably. In general, sexual activity is high in the first trimester of pregnancy, then declines to levels lower than among women not pregnant/postpartum, and is at its lowest in the first months postpartum. Adjusted for age and survey, pooled results show HIV‐negative pregnant women are less likely to have an HIV‐positive partner compared to those not pregnant/postpartum (risk ratio (RR) = 0.78, 95% CI = 0.68–0.89) and comparing the postpartum period (RR = 0.85, 95% CI = 0.73–0.99). Estimated population‐level risk for HIV acquisition and acute infection in pregnancy/postpartum was lower than would be inferred directly from per‐condomless‐coital‐act estimates in most countries, over the time of most risk of mother‐to‐child transmission, though there was variation by country and month of pregnancy/postpartum. Conclusions Estimates of population‐level HIV acquisition risk in sub‐Saharan Africa should not be taken directly from per‐condomless‐coital‐act studies to estimate vertical transmission. Changes in sexual behaviour and differences in HIV‐serodiscordancy during pregnancy/postpartum reduce the impact of increased risk of HIV acquisition per‐condomless‐coital‐act, this will vary by region.

Abstract
Introduction: A diagnosis of HIV does not affect the well-being of mothers alone but also affects how they care for their children. The aim of this study was to explore how mothers who were diagnosed with HIV when pregnant or when their children became ill experience raising children living with HIV. The purpose was to understand how a diagnosis of HIV impacts mothering their children at different points on the mothering journey. Methods: Using descriptive phenomenological enquiry, interviews were conducted with 28 mothers recruited via purposeful sampling from clinics in health district in South Africa. The interviews were audiotaped, transcribed verbatim, and analysed following the thematic approach. Results: The mothers found mothering a child living with HIV stressful and associated with constant thoughts of death. The burden of mothering was increased for mothers who had to confront emotions of self-blame and guilt for unintentionally infecting the child. They used secrecy to protect their children from the social consequences of a diagnosis of HIV. The thought of living with HIV weighed on them every day and they expressed their experience of intense feelings of chronic worry, anxiety, and sadness. The findings identified high levels of stress, with the mothers expressing emotions suggestive of depression. With time, they accepted living with HIV and embraced motherhood, and became better mothers. Conclusion: The negative coping strategies used to deal with the child’s HIV diagnosis and high levels of stress and anxiety identified in the study underscore the need to address the psychosocial needs of mothers living with HIV. There is need to provide psychosocial support and continuous counselling for these mothers post diagnosis and upon a positive HIV diagnosis of the child to women enrolled in the prevention of mother to child transmission of HIV programme.

[PMID: 32615324 DOI: 10.1016/j.ijid.2020.06.081] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Revised: 06/22/2020] [Accepted: 06/24/2020] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND Vertical transmission is the predominant route for acquisition of HIV infection in children, either in utero, intrapartum or postnatally through breast feeding. Less frequently, children may acquire HIV by horizontal transmission. Horizontal transmission may be healthcare-associated (infusion of HIV-contaminated blood products, use of contaminated needles, syringes and medical equipment, or through ingestion of HIV in expressed breastmilk). Community-acquired HIV transmission to children may occur following surrogate breastfeeding, pre-mastication of food, and sexual abuse. METHODS Children with suspected horizontally acquired HIV infection were identified by retrospective folder review of existing patients (2004-2014) and by prospective interview and examination of new patients (from 2009 onwards), at a hospital-based paediatric antiretroviral clinic in Cape Town, South Africa. The global literature on horizontal HIV transmission to children (1 January 1986-1 November 2019) was reviewed, to contextualize the local findings. RESULTS Among the 32 children with horizontal HIV transmission (15 identified retrospectively and 17 prospectively), the median age at first diagnosis was 79 months (interquartile range 28.5-91.5); most children (90.6%) had advanced HIV disease at presentation. HIV transmission was considered healthcare-associated in 15 (46.9%), community-associated in ten (31.3%), possibly healthcare or community-associated in five (15.6 %); and unknown in two children (6.3%). CONCLUSION Horizontal HIV transmission to children is an important public health issue, with prevention efforts requiring intervention at healthcare facility- and community-level. Greater effort should be made to promptly identify and comprehensively investigate each horizontally HIV-infected child to establish possible routes of transmission and inform future prevention strategies.
