RESUMO

BACKGROUND: HIV early infant diagnosis (HEID) at the centralized laboratory faces many challenges that impact the cascade of timely HEID. Point of Care (PoC) HEID has shown to reduce test turnaround times, allow for task shifting and has the potential to reduce infant mortality. We aimed at assessing the feasibility of nurse based PoC-HEID in five facilities of Mbeya region. METHODS: We analysed data from healthcare workers at five obstetric health facilities that participated in the BABY study which enrolled mothers living with HIV and their HIV exposed infants who were followed up until 6 weeks post-delivery. Nurses and laboratory personnel were trained and performed HEID procedures using the Xpert HIV-1 Qual PoC systems. Involved personnel were interviewed on feasibility, knowledge and competency of procedures and overall impression of the use of HIV-1 Qual PoC system in clinical settings. RESULTS: A total of 28 health care workers (HCWs) who participated in the study between 2014 and 2016 were interviewed, 23 being nurses, 1 clinical officer, 1 lab scientist and 3 lab technicians The median age was 39.5 years. Majority of the nurses (22/24) and all lab staff were confident using Gene Xpert PoC test after being trained. None of them rated Gene Xpert handling as too complicated despite minor challenges. Five HCWs (5/24) reported power cut as the most often occurring problem. As an overall impression, all interviewees agreed on PoC HEID to be used in clinical settings however, about half of them (11/24) indicated that the PoC-HEID procedures add a burden onto their routine workload. CONCLUSION: Overall, health care workers in our study demonstrated very good perceptions and experiences of using PoC HEID. Efforts should be invested on quality training, targeted task distribution at the clinics, continual supportive supervision and power back up mechanisms to make the wide-scale adoption of nurse based PoC HEID testing a possibility.

RESUMO

INTRODUCTION: To prevent vertical HIV transmission and ensure healthy mothers and children, pregnant women with HIV must remain on antiretroviral treatment (ART) for life. However, motivation to remain on ART may decline beyond the standard 2-year breastfeeding/postpartum period. We assessed attrition and retention in ART care among women with HIV up to 6 years since enrolment in vertical transmission prevention services in Dar es Salaam, Tanzania. METHODS: A prospective cohort of 22,631 pregnant women with HIV were enrolled in vertical transmission prevention services between January 2015 and December 2017 in routine healthcare settings and followed-up to July 2021. Kaplan-Meier was used to estimate time to ART attrition (died, stopped ART or was lost to follow-up [no show ≥90 days since scheduled appointment]) and the proportion retained in care. Cox proportional hazard models were used to estimate adjusted hazard ratios (aHR) of ART attrition in relation to predictors. RESULTS: Participants were followed-up to 6 years for a median of 3 years (IQR: 0.1-4). The overall ART attrition rate was 13.8 per 100 person-years (95% CI: 13.5-14.1), highest in the first year of enrolment at 27.1 (26.3-27.9), thereafter declined to 9.5 (8.9-10.1) in year 3 and 2.7 (2.1-3.5) in year 6. The proportion of women retained in care were 78%, 69%, 63%, 60%, 57% and 56% at 1, 2, 3, 4, 5 and 6 years, respectively. ART attrition was higher in young women aged <20 years (aHR 1.63, 95% CI: 1.38-1.92) as compared to 30-39 year-olds and women enrolled late in the third versus first trimester (aHR 1.29, 95% CI: 1.16-1.44). In contrast, attrition was lower in older women ≥40 years, women who initiated ART before versus during the index pregnancy and women attending higher-level health facilities. CONCLUSIONS: ART attrition among women with HIV remains highest in the first year of enrolment in vertical transmission prevention services and declines markedly following a transition to chronic HIV care. Targeted interventions to improve ART continuity among women with HIV during and beyond prevention of vertical transmission are vital to ending paediatric HIV and keeping women and children alive and healthy.

RESUMO

Human immunodeficiency virus (HIV) viral load (VL) monitoring was likely interrupted during the Coronavirus disease 2019 (COVID-19) pandemic. We used routine data on repeat VL testing among 667 prevention of vertical HIV transmission (PVT) clients in Ehlanzeni district, to determine compliance to VL testing recommendations and associated factors during different time periods: pre-COVID-19, transition, and COVID-19. Descriptive and multivariable Poisson regression analyses were conducted, with and without including revised PVT-guidelines rolled out in January-2020. Among 405 women with ≥ 2 VL tests, the overall median age was 30 years (interquartile range: 26-35 years). Compliance to recommended VL testing guidelines ranged between 81.5% (172/211) and 92.3% (191/207) at different time periods. Across all three periods and when revised PVT-guidelines were used, being compliant was significantly reduced among those with earliest VL = 50-999 copies/ml (incidence rate ratio (IRR) = 0.71 [95% confidence interval (CI) 0.61-0.82], p value < 0.001) and VL ≥ 1000 copies/ml (IRR = 0.18 [95% CI 0.09-0.36], p value < 0.001). When guideline revisions were excluded, compliance was only significantly reduced among those with VL ≥ 1000 copies/ml (IRR = 0.14 [95% CI 0.06-0.32], p value < 0.001) and increased during the COVID-19 period versus pre-COVID-19 (IRR = 1.10 [95% CI 1.05-1.15], p value < 0.001). Similar significant associations between compliance and VL level were observed when the COVID-19 period was analyzed separately. Significantly increased compliance to VL testing among the 25-34 years age-group versus younger women was also observed across all periods. These results highlight the importance of strengthening strategies such as short message service reminders and educational messaging, reaching all age-groups, to fast-track implementation targets for VL monitoring.

RESUMO

INTRODUCTION: With the scaling up of vertical HIV transmission prevention programmes, the HIV-related population profile of children in South Africa has shifted. We described temporal changes in HIV-related characteristics of children, aged ≤3 years (up to the third birthday), with infectious disease hospitalisations across the Western Cape province. METHODS: We used routinely collected electronic data to identify children born in the Western Cape with infectious disease hospital records for lower respiratory tract infections, diarrhoea, meningitis and tuberculous meningitis, from 2008 to 2021. Linked maternal and child unique identifiers were used to extract pregnancy, HIV-related, laboratory, pharmacy and hospitalisation data. We described temporal changes in child HIV exposure and acquisition status, timing of maternal HIV diagnosis and antiretroviral therapy (ART) start, infant exposure to maternal ART and timing thereof, and maternal CD4 and HIV viral load closest to delivery. We used logistic and multinomial regression to assess changes in characteristics between the Pre-Option B+ (2008-2013), Option B+ (2013-2016) and Universal ART periods (2016-2021). RESULTS: Among 52,811 children aged ≤3 years with hospitalisations, the proportion living with HIV dreased from 7.0% (2008) to 1.1% (2021), while those exposed to HIV and uninfected increased from 14.0% (2008) to 16.1% (2021) with a peak of 18.3% in 2017. Among mothers with HIV (n = 9873), the proportion diagnosed with HIV and starting ART before pregnancy increased from 20.2% to 69.2% and 5.8% to 59.0%, respectively, between 2008 and 2021. Children hospitalised during the Universal ART period had eight times higher odds (Odds Ratio: 8.41; 95% CI: 7.36-9.61) of exposure to maternal ART versus children admitted Pre-Option B+. Among mothers of children exposed to HIV and uninfected with CD4 records (n = 7523), the proportion with CD4 <350 cells/µl decreased from 90.6% (2008) to 27.8% (2021). CONCLUSIONS: In recent years, among children hospitalised with infectious diseases, there were fewer children with perinatally acquired HIV, while an increased proportion of those without HIV acquisition are exposed to maternal HIV and ART. There is a need to look beyond paediatric HIV prevalence and consider child exposure to HIV and ART among children without HIV, when assessing the HIV epidemic's impact on child health services.

RESUMO

Socioeconomic factors such as poor health and poor nutrition in low- and middle-income countries (LMICs) may favour inflammatory reactions, thus contributing to the recurrence of rheumatic fever (RF) and thereby modifying trends in rheumatic heart disease (RHD). Apart from epidemiological studies, studies of HIV infections in RHD patients are limited. This systematic review synthesises data on the prevalence and impact of HIV infections or AIDS on RHD from PubMed, Scopus, Web of Science databases up to April 2021. The outcomes were managed using PRISMA guidelines. Of a total of 15 studies found, 10 were eligible for meta-analyses. Meta-analysis found that 17% (95 % CI 8-33, I2 = 91%) of adults in cardiovascular disease (CVD) cohorts in Southern Africa are HIV positive. The proportion of RHD diagnosed among people living with HIV was 4% (95% CI 2-8, I2 = 79%) for adults but lower [2% (95% CI 1-4, I2 = 87%)] among perinatally infected children. Despite limited reporting, HIV-infected patients with RHD are prone to other infections that may enhance cardiac complications due to poor immunological control. PROSPERO registration number: CRD42021237046.

RESUMO

INTRODUCTION: Infant HIV prophylaxis with broadly neutralizing anti-HIV antibodies (bNAbs) could provide long-acting protection against vertical transmission. We sought to estimate the potential clinical impact and cost-effectiveness of hypothetical bNAb prophylaxis programmes for children known to be HIV exposed at birth in three sub-Saharan African settings. METHODS: We conducted a cost-effectiveness analysis using the CEPAC-Pediatric model, simulating cohorts of infants from birth through death in Côte d'Ivoire, South Africa and Zimbabwe. These settings were selected to reflect a broad range of HIV care cascade characteristics, antenatal HIV prevalence and budgetary constraints. We modelled strategies targeting bNAbs to only WHO-designated "high-risk" HIV-exposed infants (HR-HIVE) or to all HIV-exposed infants (HIVE). We compared four prophylaxis approaches within each target population: standard of care oral antiretroviral prophylaxis (SOC), and SOC plus bNAbs at birth (1-dose), at birth and 3 months (2-doses), or every 3 months throughout breastfeeding (Extended). Base-case model inputs included bNAb efficacy (60%/dose), effect duration (3 months/dose) and costs ($60/dose), based on published literature. Outcomes included paediatric HIV incidence and incremental cost-effectiveness ratios (ICERs) calculated from discounted life expectancy and lifetime HIV-related costs. RESULTS: The model projects that bNAbs would reduce absolute infant HIV incidence by 0.3-2.2% (9.6-34.9% relative reduction), varying by country, prophylaxis approach and target population. In all three settings, HR-HIVE-1-dose would be cost-saving compared to SOC. Using a 50% GDP per capita ICER threshold, HIVE-Extended would be cost-effective in all three settings with ICERs of $497/YLS in Côte d'Ivoire, $464/YLS in South Africa and $455/YLS in Zimbabwe. In all three settings, bNAb strategies would remain cost-effective at costs up to $200/dose if efficacy is ≥30%. If the bNAb effect duration were reduced to 1 month, the cost-effective strategy would become HR-HIVE-1-dose in Côte d'Ivoire and Zimbabwe and HR-HIVE-2-doses in South Africa. Findings regarding the cost-effectiveness of bNAb implementation strategies remained robust in sensitivity analyses regarding breastfeeding duration, maternal engagement in postpartum care, early infant diagnosis uptake and antiretroviral treatment costs. CONCLUSIONS: At current efficacy and cost estimates, bNAb prophylaxis for HIV-exposed children in sub-Saharan African settings would be a cost-effective intervention to reduce vertical HIV transmission.

RESUMO

BACKGROUND: Despite high coverage of maternal and child  health services in Mozambique, prevention of mother-to-child transmission of HIV (PMTCT) cascade outcomes remain sub-optimal. Delivery effectiveness is modified by health system preparedness. Identifying modifiable factors that impact quality of care and service uptake can inform strategies to improve the effectiveness of PMTCT programs. We estimated associations between facility-level modifiable health system readiness measures and three PMTCT outcomes: Early infant diagnosis (polymerase chain reaction (PCR) before 8 weeks of life), PCR ever (before or after 8 weeks), and positive PCR test result. METHODS: A 2018 cross-sectional, facility-level survey was conducted in a sample of 36 health facilities covering all 12 districts in Manica province, central Mozambique, as part of a baseline assessment for the SAIA-SCALE trial (NCT03425136). Data on HIV testing outcomes among 3,427 exposed infants were abstracted from at-risk child service registries. Nine health system readiness measures were included in the analysis. Logistic regressions were used to estimate associations between readiness measures and pediatric HIV testing outcomes. Odds ratios (OR) and 95% confidence intervals (95%CI) are reported. RESULTS: Forty-eight percent of HIV-exposed infants had a PCR test within 8 weeks of life, 69% had a PCR test ever, and 6% tested positive. Staffing levels, glove stockouts, and distance to the reference laboratory were positively associated with early PCR (OR = 1.02 [95%CI: 1.01-1.02], OR = 1.73 [95%CI: 1.24-2.40] and OR = 1.01 [95%CI: 1.00-1.01], respectively) and ever PCR (OR = 1.02 [95%CI: 1.01-1.02], OR = 1.80 [95%CI: 1.26-2.58] and OR = 1.01 [95%CI: 1.00-1.01], respectively). Catchment area size and multiple NGOs supporting PMTCT services were associated with early PCR testing OR = 1.02 [95%CI: 1.01-1.03] and OR = 0.54 [95%CI: 0.30-0.97], respectively). Facility type, stockout of prophylactic antiretrovirals, the presence of quality improvement programs and mothers' support groups in the health facility were not associated with PCR testing. No significant associations with positive HIV diagnosis were found. CONCLUSION: Salient modifiable factors associated with HIV testing for exposed infants include staffing levels, NGO support, stockout of essential commodities and accessibility of reference laboratories. Our study provides insights into modifiable factors that could be targeted to improve PMTCT performance, particularly at small and rural facilities.

RESUMO

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.

RESUMO

BACKGROUND: Mother-to-child transmission (MTCT) is the main mode of HIV transmission in children under 15 years old. This problem is significant in the Sub-Saharan African countries, where more than 80% of children living with HIV are found. Previous studies in Ethiopia present inconsistent and inconclusive findings on the prevalence and associated factors of MTCT of HIV. Therefore, this study was conducted to determine the pooled prevalence of MTCT of HIV and its associated factors in Ethiopia. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. All published studies were retrieved using relevant search terms in MEDLINE, PUBMED, Cochrane Library, EMBASE, Google Scholar, CINAHL, and African Journals Online databases. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used to critically appraise articles. STATA version 14 software was used to perform the Meta-analysis. The I2 statistics was used to test heterogeneity and publication bias was assessed using Begg's and Egger's tests. Odds ratio (OR) with 95% confidence interval (CI) was presented using forest plots. RESULTS: A total of nine studies, 3688 mother-baby pairs, were included in this meta-analysis. The pooled prevalence of MTCT of HIV in Ethiopia was 9.93% (95% CI: 7.29, 12.56). The subgroup analysis showed a higher prevalence of MTCT of HIV in Dire Dawa City Administration (15.7%) and lowest in Southern Nations, Nationality and Peoples Region (SNNPR) (4.16%). Associated factors with MTCT of HIV include: mixed feeding, OR = 7.46 (95%CI: 4.71, 11.81), absence of infant ARV prophylaxis, OR = 7.89 (95%CI: 4.32, 14.42), home delivery, OR = 5.08 (95%CI: 2.32, 11.15), and absence of maternal PMTCT intervention, OR = 7.13 (95% CI: 3.31, 15.35). CONCLUSIONS: Almost one in ten HIV exposed infants become HIV positive in Ethiopia. Factors like: mixed feeding, the absence of infant ARV prophylaxis, home delivery and absence of mother's PMTCT intervention were significantly associated with MTCT of HIV. Therefore, the governmental and non-governmental organizations need to focus on the identified factors and work towards improving the prevention of mother to child transmission of HIV (PMTCT) program.

RESUMO

BACKGROUND: Despite recommendations for disclosure of HIV status to children living with HIV (CLHIV), fewer than half of CLHIV at the Instituto Nacional de Salud del Niño (INSN) in Lima, Peru, have had disclosure. How and when the disclosure process for CLHIV should take place in Peru has not been studied. METHODS: We conducted a qualitative study at INSN to explore perceptions and experiences of 6 health care providers (HCPs), 14 disclosed and nondisclosed CLHIV (8-17 years), and their 14 caregivers regarding knowledge of illness, disclosure of HIV status, and appropriate disclosure approaches. RESULTS: Disclosed children wanted to be told their diagnosis earlier. Nondisclosed children expressed frustration taking medications. Caregivers and HCPs discussed motivations to disclose, including educating, honesty, improving medication adherence, and preventing secondary transmission. CONCLUSION: Culturally appropriate guidelines and training for HCPs and caregivers are needed to support disclosure of children's HIV status and ongoing support for CLHIV.

RESUMO

OBJECTIVES: The objective was to determine whether the proportion of pregnant women with unknown antenatal HIV-infection status is declining over time in British Columbia (BC) and whether associated factors are amenable to intervention. METHODS: Through a retrospective cohort study of all deliveries in the British Columbia Perinatal Data Registry from 2005 to 2011, we examined the association between year of delivery and no recorded antenatal HIV test result. The trend in unknown antenatal HIV-infection status over time was evaluated by the Cochran-Mantel-Haenzsel test and multivariable logistic regression was used to determine the odds of unknown antenatal HIV-infection status by year of delivery. RESULTS: A total of 299 771 deliveries were included; 9.1% had unknown antenatal HIV-infection status with a declining trend from 12.7% to 5.5% from 2005 to 2011 (P <0.0001). Adjusted for maternal age, parity, gestation, and number of antenatal visits, pregnant women were 64% less likely to not have antenatal HIV testing in 2011 compared to 2005 (adjusted odds ratio [aOR] 0.36; 95% CI 0.34-0.38). The odds of no antenatal HIV testing were 54% higher in multiparous compared to primiparous women (aOR 1.54; 95% CI 1.49-1.58), and each additional antenatal visit reduced the odds of no antenatal HIV testing by 8% (aOR 0.92; 95% CI 0.92-0.93). CONCLUSION: The declining trend in unknown antenatal HIV-infection status in BC is encouraging. Consistent with Canadian and BC HIV testing guidelines, further strengthening of routine testing at the first antenatal visit in all pregnancies irrespective of previous HIV testing, particularly in multiparous women, could achieve universal pregnancy HIV testing in BC.

RESUMO

Despite the wide availability of antiretroviral therapy (ART) prophylaxis during pregnancy, >150,000 infants become infected through mother-to-child transmission (MTCT) of HIV worldwide. It is likely that additional intervention strategies, such as a maternal HIV vaccine, will be required to eliminate pediatric HIV infections. A deeper understanding of the fine specificity and function of maternal HIV envelope (Env)-specific responses that provide partial protection against MTCT will be critical to inform the design of immunologic strategies to curb the pediatric HIV epidemic. Recent studies have underlined a role of maternal HIV Env-specific neutralizing and non-neutralizing responses in reducing risk of MTCT of HIV and in prolonging survival rates in HIV-infected infants. However, critical gaps in our knowledge include (A) the specific role of maternal autologous-virus IgG-neutralizing responses in driving the selection of infant transmitted founder (T/F) viruses and (B) Env mechanisms of escape from maternal autologous virus-neutralizing antibodies (NAbs). A more refined understanding of the fine specificities of maternal autologous virus NAbs and ways that maternal circulating viruses escape from these antibodies will be crucial to inform maternal vaccination strategies that can block MTCT to help achieve an HIV-free generation.

RESUMO

As young people living with HIV age, transition to adult care is increasingly required. The aim of our study was to describe how a care transition program was developed in an HIV adult clinic in Genoa, Italy. This is a descriptive study including 45 HIV-infected patients who participated in the transition process from a pediatric unit to an adult Infectious Diseases Unit, which started in 2000. A dedicated day, patient-customized environment, psychological support, and all health services in one site were provided. In 2014, a survey form was created to investigate the efficacy of the transition. At survey compilation time, 38 patients (84.4%) were retained in care, 2 were lost to follow-up, 2 were transferred to another adult clinic, and 3 had died. We highlight the importance of planning the transition process and the role of the interprofessional team to guarantee a successful transition for HIV-infected children and adolescents.

RESUMO

The vertical transmission of HIV occurs when an HIV-positive woman passes the virus to her baby during pregnancy, delivery or breastfeeding. The World Health Organization's (WHO) Guidelines on HIV and infant feeding 2010 recommends exclusive breastfeeding for HIV-positive mothers in resource-limited settings. Although evidence shows that following this strategy will dramatically reduce vertical transmission of HIV, full implementation of the WHO Guidelines has been severely limited in sub-Saharan Africa. This paper provides an analysis of the role of ideas, interests and institutions in establishing barriers to the effective implementation of these guidelines by reviewing efforts to implement prevention of vertical transmission programs in various sub-Saharan countries. Findings suggest that WHO Guidelines on preventing vertical transmission of HIV through exclusive breastfeeding in resource-limited settings are not being translated into action by governments and front-line workers because of a variety of structural and ideological barriers. Identifying and understanding the role played by ideas, interests and institutions is essential to overcoming barriers to guideline implementation.

RESUMO

Foram analisadas as práticas e os sentidos do aconselhamento para gestantes submetidas ao teste anti-HIV na admissão para o parto, e para profissionais de saúde que atuam na assistência à maternidade em Salvador, Brasil. Foi realizado um estudo qualitativo em uma maternidade, com observação participante e entrevistas semiestruturadas com 13 puérperas sem diagnóstico prévio para o HIV e sete profissionais de saúde. Observou-se que o exame anti-HIV é realizado de forma compulsória, sem considerar a autonomia da gestante, e que o aconselhamento se limita a informar o diagnóstico e dar orientações no pós-teste somente àquelas cujos resultados foram positivos. Os sentidos que permeiam o exame, assim como o entendimento da experiência e os significados construídos pelas puérperas, sobretudo quando se descobrem positivas para o HIV, não são abordados pelos profissionais, que não se sentem capacitados para acolherem a subjetividade das pacientes.


The practices and meanings of counseling for pregnant women who underwent HIV testing on admission for delivery, and for healthcare professionals working in childbirth care in Salvador, Brazil, were analyzed. A qualitative study was conducted in a maternity hospital using participant observation and semi-structured interviews with 13 puerperae with no previous diagnosis of HIV and with seven healthcare professionals. It was observed that the anti-HIV test was done compulsorily, without taking into account the pregnant woman's autonomy. The counseling was limited to informing the diagnosis and giving guidance after the test, only to the HIV-positive women. The meanings that permeated the test and the comprehension of the experience and meanings constructed by the women, especially when they were discovered to be HIV-positive, were not addressed by the professionals, who did not feel qualified to deal with the patients' subjectivity.


Fueron analizadas las prácticas y los sentidos de aconsejador para gestantes sometidas a pruebas anti-VIH durante la admisión para el parto, y para profesionales de salud que trabajan en la asistencia en maternidad de Salvador, Bahia, Brasil. Fue realizado un estudio cualitativo en una maternidad mediante observación participante y entrevistas con 13 puérperas sin diagnostico previo de VIH y siete profesionales de salud. La prueba anti-VIH es realizada de forma obligatoria sin tomar en cuenta la autonomía de la gestante y que el aconsejador se limita a informar el diagnóstico y orientaciones posteriores a la prueba, sólo para mujeres cuyos resultados son positivos. Experiencias y significados construidos por las puérperas, principalmente cuando se descubren positivas para el VIH, no son abordados por los profesionales de salud, que no se sienten capacitados para lidiar con la subjetividad de las pacientes.
