Quantifying the gender gap in the HIV care cascade in southern Mozambique: We are missing the men

High prevalence of low-level viremia among infants initiated on antiretroviral drugs following mother-to-child transmission of HIV

BACKGROUND

With the current elimination of mother to child transmission (EMTCT) of HIV, the number of HIV-positive newborns has greatly reduced. Some countries have successfully eliminated HIV infections among newborn babies.

METHODS

This study was nested within the DRIBS (Drug Resistance testing among Infants at Baseline Study), which enrolled 100 infants at the time of treatment initiation between 2017 and 2023. Infants were followed for two years. Viral load (VL) was measured every six months and after completion of the three sessions of intensified adherence counseling (IAC). IAC and HIV drug resistance testing were performed for VL greater than 1000 copies/ml.

RESULTS

The median age at diagnosis was 79 (IQR, 57.75;140.75) days, with 4% of patients diagnosed within 6 weeks after delivery. The median age at the initiation of therapy was 110.5 (IQR, 87.0-162.0) days. The median baseline %CD4 was 26 (IQR, 18.75;32), with 9% of the babies being severely immunosuppressed (%CD4 < 15%). The median baseline log viral load was 4.44 (IQR, 3.19-5.58). At six months, 30% and 60% of the patients had a VL < 50 and < 1000 copies/ml, respectively. At 12 months, 36% and 69% of patients had a VL < 50 and < 1000 copies/ml, respectively. At 24 months, 63% and 83% had VL < 50 and < 1000 copies/ml, respectively. Post-IAC VL revealed that 35% of the children had low-level viremia (LLV) compared to mothers 11.5%. Kaplan-Meyer survival estimates showed that while it took 72 weeks for 50% of the mothers and infants to attain a VL less than 1000 copies/ml, it took 96 weeks for the infants to attain a VL < 50 copies/ml.

CONCLUSION

A Viral load < 1000 copies/ml is achieved much more slowly in pediatric patients, implying that it might take longer for babies to achieve the third 95 (95% virally suppressed) of the UNAIDS targets. Furthermore, the greater prevalence of LLV in pediatric patients than in mothers has important implications for the response to therapy.

Integrating status-neutral and targeted HIV testing in Zimbabwe: A complementary strategy

INTRODUCTION

Zimbabwe exclusively implemented targeted HIV testing until 2022 when Status-neutral testing was embraced. Whilst targeted testing aims to expand access and uptake of testing among high-risk individuals, status-neutral testing emphasizes post-test linkage to prevention and treatment services. To address how the two concepts relate in practice, we explored how status-neutral and targeted testing concepts correlate, in developing a double-edged strategy for effective case identification and linkage to prevention and treatment.

METHODS

We conducted a cross-sectional study on 36 multi-stage sampled sites across 4/10 provinces of Zimbabwe. A national screening algorithm was used to determine patient risk profiling and eligibility for testing. Screened-out patients were offered HIVST. Both screened and non-screened patients were tested and analysed for positivity ratios and linkage to post-test services. Epicollect5 was used to collect data and analysed using EpiData software and Stata. Univariate, bivariate and multivariate analyses were conducted at a 5% significance level.

RESULTS

Of 23,058 HIV tests done, females constituted 55% (n = 12,698), whilst 63.5% (n = 14,650) were retested. Through screening, at-risk patients contributed 75.1% to the overall positivity (1,296/1,727), from 66% (n = 15,289) of the total HIV tests conducted. All screened-out patients were non-reactive on HIVST: 1,182/1,182. The 45-49-year category was 3.6 times more likely to test positive (a95%CI:2.67,4.90). Males were 3.09 times more likely to test positive in adjusted analysis (a95%CI: 2.74, 3.49). First tests were 65% more likely to test HIV positive (a95%CI: 1.43, 1.91) whilst screened patients were 3.89 times more likely to link to HIV prevention services (a95%CI: 3.05, 4.97), against 25.5% (n = 1,871) linkage among patients not screened.

CONCLUSION

The complementarity of the status-neutral and targeted testing approaches is evident from our results. By prioritizing high-risk individuals for testing and ensuring comprehensive linkage to both prevention and treatment services, these integrated strategies can effectively identify and manage people living with HIV. This combined approach optimizes resource use, particularly in low- and middle-income countries, and contributes to improved health outcomes and reduced HIV transmission rates.

Paediatric healthcare in Manhiça district through a gender lens: a retrospective analysis of 17 years of morbidity and demographic surveillance data

Background

Sex and gender are important determinants of health. Gender-based health inequities in the paediatric population have been reported in various countries, but data remain limited. In Mozambique, research on this topic is very scarce. Here we aimed to explore whether boys and girls in Manhiça district, southern Mozambique, differ in access to and provision of healthcare.

Methods

This retrospective analysis includes data on all paediatric (<15 years old) visits to six outpatient clinics and admissions to one hospital in Manhiça district from 2004 to 2020, collected through the morbidity surveillance system of the Manhiça Health and Demographic Surveillance System (HDSS). We compared characteristics and outcomes between boys and girls using descriptive statistics, standardised mean differences, and logistic regression. Post-discharge events were analysed using Cox proportional hazards regression and Fine-Gray competing risk regression. Minimum community-based incidence rates of outpatient clinic visits and hospitalisations were calculated using demographic surveillance data from the Manhiça HDSS and analysed with negative binomial regression.

Results

Girls represented 49.2% (560 630 out of 1 139 962) of paediatric visits to outpatient clinics and 45.1% (18 625 out of 41 278) of hospitalisations. The girls-to-boys incidence rate ratio (IRR) for hospitalisations was 0.81 (95% confidence interval (CI) = 0.79-0.84). Both boys and girls experienced symptoms for a median duration of one day (interquartile range (IQR) = 1-2) before seeking care. Severe manifestations at presentation to an outpatient clinic or upon hospitalisation tended to be less frequent in girls (girls-to-boys odds ratios (ORs) = 0.71-1.11). Girls were less frequently referred or admitted to hospital after an outpatient clinic visit (OR = 0.82; 95% CI = 0.79-0.86 and OR = 0.85; 95% CI = 0.84-0.87, respectively). The hospital case fatality ratio was 4.1% in boys and 4.2% in girls. The median duration of hospitalisation was three days (IQR = 2-5) and did not differ between boys and girls. Revisits to outpatient clinics, hospital readmissions, and hospital post-discharge mortality were similar in both groups.

Conclusions

Girls had fewer referrals and admissions to hospital in Manhiça district, but they were also less likely to present with severe manifestations. Other studied indicators of healthcare access and provision were overall similar for boys and girls. Further research is needed to continue assessing potential gender biases and sex differences in paediatric healthcare in Mozambique.

Effect of the Ten-valent Pneumococcal Conjugate Vaccine on Invasive Pneumococcal Disease and Pneumonia in Infants Younger Than Ten Weeks of Age in Southern Mozambique: A Population-based Prospective Surveillance Study

BACKGROUND

Mozambique introduced 10-valent-pneumococcal conjugate vaccine (PCV10) in 2013. We aimed to evaluate the indirect effect of PCV10 on invasive pneumococcal disease (IPD) and clinical severe pneumonia (CSP) in infants aged less than 10 weeks.

METHODS

Routine surveillance data for IPD and CSP among admitted infants less than 10 weeks of age were analyzed to compare IPD and CSP incidence using demographic surveillance data from pre- and post-PCV10 periods. IPD was defined as isolation of pneumococcus from blood or cerebrospinal fluid, and CSP according to World Health Organization criteria.

RESULTS

The incidence of IPD and CSP among infants less than 10 weeks decreased by 87% [incidence rate ratio (IRR): 0.13; 95% confidence interval (CI): 0.02-0.95] from 283/100,000 in the pre-PCV to 36/100,000 children year at risk (CYAR) post-PCV, and by 62% (IRR: 0.38; 95% CI: 0.27-0.52) from 4100/100,000 pre-PCV to 1550/100,000 CYAR post-PCV periods, respectively. Vaccine-type IPD incidence declined by 92% (IRR: 0.18; 95% CI: 0.02-1.34) from 205/100,000 pre-PCV to 36/100,000 CYAR post-PCV, though the reduction was not statistically significant. The mortality rate due to IPD among infants less than 10 weeks declined from 47/100,000 CYAR in the pre-PCV to 0 in the post-PCV period. Mortality due to CSP declined by 29% (IRR: 0.71; 95% CI: 0.34-1.50), from 457/100,000 CYAR in the pre-PCV to 324/100,000 in the post-PCV periods.

CONCLUSIONS

PCV10 introduction led to substantial declines in the incidence of IPD, CSP and associated mortality in infants too young to be vaccinated (less than 10 weeks) in Mozambique, suggesting indirect protection.

Core components of male-specific person-centred HIV care: a qualitative analysis from client and healthcare worker perspectives in Malawi

Introduction

Person-centred care (PCC) improves clinical outcomes for people living with HIV. Heterosexual men in sub-Saharan Africa are under-represented in HIV care, yet PCC interventions for men are lacking. We identified core components of a PCC intervention for men living with HIV (MLHIV) in Malawi from both client and healthcare worker (HCW) perspectives, as well as strategies for implementation in routine settings.

Methods

MLHIV≥15 years and not in care were enrolled in parent randomised trials to test the impact of male-tailored HIV services on 6-month treatment outcomes (n=1303). Clients received a PCC package including male-specific counselling+facility ART distribution or outside-facility ART distribution. 50 male clients were recruited for qualitative in-depth interviews using stratified random sampling to assess perceptions of the PCC packages. Focus group discussions were conducted with HCWs who delivered the intervention to understand implementation strategies and potential considerations for scale-up in routine settings. Interviews were audio recorded, translated into English, transcribed and coded in Atlas.ti V.9 and analysed using thematic analysis.

Results

36 MLHIV and 20 HCWs (10 lay cadre and 10 nurses) were interviewed between February and July 2022. Positive interactions with HCWs-characterised by kindness, reciprocity, privacy and focused conversations-and compelling, relevant counselling were considered the most important components of male PCC. While outside-facility ART dispensing was considered helpful, it was not as critical as these other components. HCWs outlined five steps to implementing male PCC: begin with kindness, apologise for past negative interactions, understand men's holistic story, provide tailored counselling and support development of strategies for adherence. HCWs believed that male PCC enhanced their ability to support male clients but emphasised the need to be integrated into routine services.

Discussion

PCC strategies that foster positive HCW relationships and addresses men's unique experiences are highly valued by MLHIV. HCWs identified several strategies for delivering PCC to MLHIV that may help close gaps in HIV care for men.

Men's perceptions of HIV self-testing in Eswatini: a qualitative study

Men in Eswatini test for HIV at lower rates compared to women despite the widespread availability of HIV testing services in the country. HIV self-test kits have been proposed as an HIV testing model to reach more men by bypassing the health facility, which is known to be a barrier for men using HIV testing services. In this study, we sought to understand men's perspectives on HIV self-testing in Eswatini. We conducted semi-structured interviews with 22 men, recruited from a rural community and from an urban men's clinic, to assess their awareness of HIV self-testing and their perceptions of it as an alternative HIV testing option. Findings show that men were aware of HIV self-testing but had concerns that left most feeling hesitant about adopting it. Many men expressed doubts about the accuracy of self-testing and their own technical competence to use the kit without supervision. They also expressed fears about testing, and possibly learning they were HIV positive, without adequate pre - and post-HIV test counseling. To allay men's fears and improve uptake of HIV self-testing, practitioners might consider innovative methods such as virtual counseling services and linking HIV self-testing to other community-based HIV care services.

HIV care retention in three multi-month ART dispensing: a retrospective cohort study in Mozambique

OBJECTIVE

Evaluate the effect of three multimonth dispensing (3MMD) of antiretroviral therapy (ART) on HIV care retention in southern Mozambique.

DESIGN

Retrospective cohort study.

METHODS

We analyzed routine health data from people with HIV (PWH) aged 10 years old and older who started ART between January 2018 and March 2021. Individuals were followed until December 2021. Cox proportional-hazards models were used to compare attrition (lost to follow-up, death, and transfer out) between 3MMD and monthly ART dispensing. Results were stratified by time on ART before 3MMD enrolment: 'early enrollers' (<6 months on ART) and 'established enrollers' (≥6 months on ART), and age groups: adolescents and youth (AYLHIV) (10-24 years) and adults (≥25 years).

RESULTS

We included 7378 PWH (25% AYLHIV, 75% adults), with 59% and 62% enrolled in 3MMD, respectively. Median follow-up time was 11.3 [interquartile range (IQR): 5.7-21.6] months for AYLHIV and 10.2 (IQR: 4.8-20.9) for adults. Attrition was lower in PWH enrolled in 3MMD compared with monthly ART dispensing, in both established (aHR AYLHIV = 0.65; 95% CI: 0.54-0.78 and aHR adults = 0.50; 95% confidence interval (CI): 0.44-0.56) and early enrollers (aHR AYLHIV = 0.70; 95% CI: 0.58-0.85 and aHR adults = 0.63; 95% CI: 0.57-0.70). Among individuals in 3MMD, male gender (aHR = 1.30; 95% CI: 1.18-1.44) and receiving care in a medium-volume/low-volume healthcare facility (aHR = 1.18; 95% CI: 1.03-1.34) increased attrition risk. Conversely, longer ART time before 3MMD enrolment (aHR = 0.93; 95% CI: 0.92-0.94 per 1 month increase) and age at least 45 years (aHR = 0.77, 95% CI: 0.67-0.89) reduced risk of attrition.

CONCLUSION

3MMD improves retention in care compared with monthly dispensing among established and early enrollers, although to a lesser extent among the latter.

Partner-Based HIV Treatment for Seroconcordant Couples Attending Antenatal and Postnatal Care in Rural Mozambique: A Cluster Randomized Controlled Trial

INTRODUCTION

There is evidence that a supportive male partner facilitates maternal HIV testing during pregnancy, increases maternal antiretroviral therapy initiation and adherence, and increases HIV-free infant survival. Most male partner engagement clinical strategies have focused on increasing uptake of couple-based HIV testing and counseling. We delivered a couple-based care and treatment intervention to improve antiretroviral therapy adherence in expectant couples living with HIV.

METHODS

We implemented a cluster randomized controlled trial for seroconcordant couples living with HIV, comparing retention (using a patient's medication possession ratio) in HIV care for a couple-based care and treatment intervention vs. standard of care services in rural Mozambique. The intervention included couple-based treatment, couple-based education and skills building, and couple-peer educator support.

RESULTS

We recruited 1080 couples to participate in the study. Using a linear mixed effect model with a random effect for clinic, the intervention had no impact on the medication possession ratio among women at 12 months. However, the intervention increased men's medication ratio by 8.77%. Our unadjusted logistic regression model found the odds of an infant seroconverting in the intervention group was 30% less than in the control group, but the results were not statistically significant.

DISCUSSION

Our study found no difference in maternal outcomes by study arm, but our intervention resulted in an improved medication possession ratio among male partners. We provide a community/clinic-based treatment framework that can improve outcomes among male partners. Further work needs to be done to improve social support for pregnant women and to facilitate prevention of vertical transmission to infants among couples living with HIV.

Enhancing HIV positivity yield in southern Mozambique: The effect of a Ministry of Health training module in targeted provider-initiated testing and counselling

In Mozambique, targeted provider-initiated HIV testing and counselling (PITC) is recommended where universal PITC is not feasible, but its effectiveness depends on healthcare providers' training. This study aimed to evaluate the effect of a Ministry of Health training module in targeted PITC on the HIV positivity yield, and identify factors associated with a positive HIV test. We conducted a single-group pre-post study between November 2018 and November 2019 in the triage and emergency departments of four healthcare facilities in Manhiça District, a resource-constrained semi-rural area. It consisted of two two-month phases split by a one-week targeted PITC training module ("observation phases"). The HIV positivity yield of targeted PITC was estimated as the proportion of HIV-positive individuals among those recommended for HIV testing by the provider. Additionally, we extracted aggregated health information system data over the four months preceding and following the observation phases to compare yield in real-world conditions ("routine phases"). Logistic regression analysis from observation phase data was conducted to identify factors associated with a positive HIV test. Among the 7,102 participants in the pre- and post-training observation phases (58.5% and 41.5% respectively), 68% were women, and 96% were recruited at triage. In the routine phases with 33,261 individuals (45.8% pre, 54.2% post), 64% were women, and 84% were seen at triage. While HIV positivity yield between pre- and post-training observation phases was similar (10.9% (269/2470) and 11.1% (207/1865), respectively), we observed an increase in yield in the post-training routine phase for women in triage, rising from 4.8% (74/1553) to 7.3% (61/831) (Yield ratio = 1.54; 95%CI: 1.11-2.14). Age (25-49 years) (OR = 2.43; 95%CI: 1.37-4.33), working in industry/mining (OR = 4.94; 95%CI: 2.17-11.23), unawareness of partner's HIV status (OR = 2.50; 95%CI: 1.91-3.27), and visiting a healer (OR = 1.74; 95%CI: 1.03-2.93) were factors associated with a positive HIV test. Including these factors in the targeted PITC algorithm could have increased new HIV diagnoses by 2.6%. In conclusion, providing refresher training and adapting the current targeted PITC algorithm through further research can help reach undiagnosed PLHIV, treat all, and ultimately eliminate HIV, especially in resource-limited rural areas.

Reasons for non-disclosure of HIV-Positive status to healthcare providers: a mixed methods study in Mozambique

BACKGROUND

Non-disclosure of known HIV status by people living with HIV but undergoing HIV testing leads to waste of HIV testing resources and distortion of estimates of HIV indicators. In Mozambique, an estimated one-third of persons who tested positive already knew their HIV-positive status. To our knowledge, this study is the first to assess the factors that prevent people living with HIV (PLHIV) from disclosing their HIV-positive status to healthcare providers during a provider-initiated counseling and testing (PICT) campaign.

METHODS

This analysis was nested in a larger PICT cross-sectional study performed in the Manhiça District, Southern Mozambique from January to July 2019, in which healthcare providers actively asked patients about their HIV-status. Patients who tested positive for HIV were crosschecked with the hospital database to identify those who had previously tested positive and were currently or previously enrolled in care. PLHIV who did not disclose their HIV-positive status were invited to participate and provide consent, and were interviewed using a questionnaire designed to explore barriers, patterns of community/family disclosure, and stigma and discrimination.

RESULTS

We found that 16.1% of participants who tested positive during a PICT session already knew their HIV-positive status but did not disclose it to the healthcare provider. All the participants reported previous mistreatment by general healthcare providers as a reason for nondisclosure during PICT. Other reasons included the desire to know if they were cured (33.3%) or to re-engage in care (23.5%). Among respondents, 83.9% reported having disclosed their HIV-status within their close community, 48.1% reported being victims of verbal or physical discrimination following their HIV diagnosis, and 46.7% reported that their HIV status affected their daily activities.

CONCLUSION

Previous mistreatment by healthcare workers was the main barrier to disclosing HIV-positive status. The high proportion of those disclosing their HIV status to their community but not to healthcare providers suggests that challenges with patient-provider relationships affect this care behavior rather than social stigma and discrimination. Improving patient-provider relationships could increase trust in healthcare providers, reduce non-disclosures, and help optimize resources and provide accurate estimates of the UNAIDS first 95 goal.

Evaluation of Omnigene-Sputum for Preservation of Sputum Samples for Diagnosis of Mycobacterium tuberculosis

In several low-income countries, the transport of sputa could take up to one week to reach the laboratories, resulting in increased contamination rates and a loss of growth. The aim of this study was to evaluate the effect of the OMNIgene-SPUTUM in preserving Mycobacterium tuberculosis on sputum samples simulating three hypothetical scenarios for conservation and/or decontamination: (1) sputum was mixed with OMN and conserved at room temperature for five days and then processed for culture (OMN); (2) sputum cultures followed the routine standing operating procedure at day 0 (STD); and (3) sputum samples were kept at room temperature for five days and mixed with the standard decontamination reagent (SDT5) and then processed for culture. The positivity rate based on smear microscopy was 36.4%, 29.1%, and 27.3% for STD, STD5, and OMN, respectively. The proportion of positive results by liquid culture (MGIT) was 39.1% (43/110) for STD, 26.4% (29/110) for STD5, and 20.0% for OMN (22/110). The overall concordance of liquid culture results was 51.8% (57/110): 37.3% (41/110) for negative results, 11.8% (13/110) for MTBC growth, and 2.7% (3/110) for contaminated results. The OMN arm showed better performance in solid culture than in liquid culture, with a notable reduction in contaminated results.

Identifying efficient linkage strategies for men (IDEaL): a study protocol for an individually randomised control trial

INTRODUCTION

Men in sub-Saharan Africa are less likely than women to initiate antiretroviral therapy (ART) and more likely to have longer cycles of disengagement from ART programmes. Treatment interventions that meet the unique needs of men are needed, but they must be scalable. We will test the impact of various interventions on 6-month retention in ART programmes among men living with HIV who are not currently engaged in care (never initiated ART and ART clients with treatment interruption).

METHODS AND ANALYSIS

We will conduct a programmatic, individually randomised, non-blinded, controlled trial. 'Non-engaged' men will be randomised 1:1:1 to either a low-intensity, high-intensity or stepped arm. The low-intensity intervention includes one-time male-specific counseling+facility navigation only. The high-intensity intervention offers immediate outside-facility ART initiation+male-specific counselling+facility navigation for follow-up ART visits. In the stepped arm, intervention activities build in intensity over time for those who do not re-engage in care with the following steps: (1) one-time male-specific counselling+facility navigation→(2) ongoing male mentorship+facility navigation→(3) outside-facility ART initiation+male-specific counselling+facility navigation for follow-up ART visits. Our primary outcome is 6-month retention in care. Secondary outcomes include cost-effectiveness and rates of adverse events. The primary analysis will be intention to treat with all eligible men in the denominator and all men retained in care at 6 months in the numerator. The proportions achieving the primary outcome will be compared with a risk ratio, corresponding 95% CI and p value computed using binomial regression accounting for clustering at facility level.

ETHICS AND DISSEMINATION

The Institutional Review Board of the University of California, Los Angeles and the National Health Sciences Research Council in Malawi have approved the trial protocol. Findings will be disseminated rapidly in national and international forums and in peer-reviewed journals and are expected to provide urgently needed information to other countries and donors.

Using testing history to estimate HIV incidence in mothers living in resource-limited settings: Maximizing efficiency of a community health survey in Mozambique

Obtaining rapid and accurate HIV incidence estimates is challenging because of the need for long-term follow-up for a large cohort. We estimated HIV incidence among women who recently delivered in southern Mozambique by leveraging data available in routine health cards. A cross-sectional household HIV-testing survey was conducted from October 2017 to April 2018 among mothers of children born in the previous four years in the Manhiça Health Demographic Surveillance System area. Randomly-selected mother-child pairs were invited to participate and asked to present documentation of their last HIV test result. HIV-testing was offered to mothers with no prior HIV-testing history, or with negative HIV results obtained over three months ago. HIV incidence was estimated as the number of mothers newly diagnosed with HIV per total person-years, among mothers with a prior documented HIV-negative test. Among 5000 mother-child pairs randomly selected, 3069 were interviewed, and 2221 reported a previous HIV-negative test. From this group, we included 1714 mothers who had taken a new HIV test during the survey. Most of mothers included (83.3%,1428/1714) had a previous documented HIV test result and date. Median time from last test to survey was 15.5 months (IQR:8.0-25.9). A total of 57 new HIV infections were detected over 2530.27 person-years of follow-up. The estimated HIV incidence was 2.25 (95% CI: 1.74-2.92) per 100 person-years. Estimating HIV incidence among women who recently delivered using a community HIV-focused survey coupled with previous HIV-testing history based on patients' clinical documents is an achievable strategy.

HIV community index testing reaches proportionally more males than facility-based testing and is cost-effective: A study from Gaza province, Mozambique

BACKGROUND

In Mozambique, 38.7% of women and 60.4% of men ages 15-59 years old living with HIV do not know their HIV status. A pilot home-based HIV counseling and testing program based on index cases in the community was implemented in eight districts in Gaza province (Mozambique). The pilot targeted the sexual partners, biological children under 14 years old living in the same household, and parents (for pediatric cases) of people living with HIV. The study aimed to estimate the cost-efficiency and effectiveness of community index testing and compare the HIV testing outputs with facility-based testing.

METHODS

Community index testing costs included the following categories: human resources, HIV rapid tests, travel and transportation for supervision and home visits, training, supplies and consumables, and review and coordination meetings. Costs were estimated from a health systems perspective using a micro-costing approach. All project costs were incurred between October 2017 and September 2018 and converted to U.S. dollars ($) using the prevailing exchange rate. We estimated the cost per individual tested, per new HIV diagnosis, and per infection averted.

RESULTS

A total of 91,411 individuals were tested for HIV through community index testing, of which 7,011 were newly diagnosed with HIV. Human resources (52%), purchase of HIV rapid tests (28%) and supplies (8%) were the major cost drivers. The cost per individual tested was $5.82, per new HIV diagnosis was $65.32, and per infection averted per year was $1,813. Furthermore, the community index testing approach proportionally tested more males (53%) than facility-based testing (27%).

CONCLUSION

These data suggest that expansion of the community index case approach may be an effective and efficient strategy to increase the identification of previously undiagnosed HIV-positive individuals, particularly males.

SARS-CoV-2 Seropositivity and HIV Viral Load Among Mozambican Pregnant Women

INTRODUCTION

Prevalence estimates of SARS-CoV-2 infection in Africa are limited, particularly among pregnant women and in those living with HIV. This study assessed the seroprevalence of SARS-CoV-2 antibodies among Mozambican HIV-infected pregnant women during the first year of the pandemic, before COVID-19 vaccines were deployed in the country.

SETTING

The study was conducted in Manhiça district, a semirural area in southern Mozambique.

METHODS

A prospective cohort study including pregnant women living with HIV was conducted from November 2019 to June 2021. Women were enrolled at the first antenatal care clinic visit and followed until postpartum. HIV viral load and IgM/IgG antibodies against SARS-CoV-2 were determined in blood samples at first antenatal care clinic visit and at delivery. Associations between SARS-CoV-2 serostatus and maternal characteristics at enrolment were analyzed.

RESULTS

A total of 397 women were enrolled. SARS-CoV-2 IgG/IgM antibodies were detected in 7.1% of women at enrolment and in 8.5% of women at delivery. Overall, SARS-CoV-2 antibodies were detected in 45 women (11.3%; 95% confidence interval 8.4 to 14.9%) during the study period; the first seropositive sample was identified in September 2020. Having undetectable HIV viral load was associated with seropositivity of SARS-CoV-2 IgG/IgM [odds ratio 3.35 (1.10 to 11.29); P = 0.039].

CONCLUSION

Seroprevalence of SARS-CoV-2 antibodies in this cohort of Mozambican unvaccinated pregnant women was similar to reported global estimates of approximately 10% in pregnancy for 2021. The findings also suggest that pregnant women with high HIV viral load may have an impaired immune response against SARS-CoV-2 and might need to be carefully managed in case of COVID-19.

The Shinyanga Patient: A Patient's Journey through HIV Treatment Cascade in Rural Tanzania

The 2016-2017 Tanzania HIV Impact Survey (THIS) reported the accomplishments towards the 90-90-90 global HIV targets at 61-94-87, affirming the need to focus on the first 90 (i.e., getting 90% of people living with HIV (PLHIV) tested). We conducted a patient-pathway analysis to understand the gap observed, by assessing the alignment between where PLHIV seek healthcare and where HIV services are available in the Shinyanga region, Tanzania. We used existing and publicly available data from the National AIDS Control program, national surveys, registries, and relevant national reports. Region-wide, the majority (n = 458/722, 64%) of THIS respondents accessed their last HIV test at public sector facilities. There were 65.9%, 45.1%, and 74.1% who could also access antiretroviral therapy (ART), CD4 testing, and HIV viral load testing at the location of their last HIV test, respectively. In 2019, the viral suppression rate estimated among PLHIV on ART in the Shinyanga region was 91.5%. PLHIV access HIV testing mostly in public health facilities; our research shows that synergies can be achieved to improve access to services further down the cascade in this sector. Furthermore, effective engagement with the private sector (not-for-profit and for-profit) will help to achieve the last mile toward ending the HIV epidemic.
