HIV Testing In sub-Saharan Africa Research Articles

HIV retesting among people living with HIV in Lesotho in 2022.

Despite widespread HIV testing in sub-Saharan Africa, regular testing among at-risk populations is crucial for effective prevention. However, reports increasingly indicate retesting among people living with HIV (PLHIV), a group that would not require additional testing since they would already have received a confirmed diagnosis. We describe the demographic characteristics of PLHIV retesters in Lesotho, report the average number of HIV tests post-diagnosis among PLHIV, and share motivations for retesting. In August 2022, a nationally representative cohort in Lesotho participated in a cell phone survey about their HIV status and testing history. Study participants were recruited from a face-to-face survey conducted in 2020, Lesotho Population Based HIV Impact Assessment survey. Of the 1523 participants called, 1111 participants responded (72.9%) and 266 reported living with HIV. We found 18.8% of people living with HIV (PLHIV) reported retesting at least once for HIV, and 58% of PLHIV who reported retesting were likely or very likely to retest for HIV in the coming year. The main reason PLHIV reported retesting was because a health care worker offered the test (61.7%) followed by self-initiated testing to confirm their status (29.1%). Among male PLHIV who had a history of retesting, 92.0% were very likely or likely to retest, compared to only 30.6% of female PLHIV. We found almost a fifth of PLHIV in Lesotho reported a history of retesting for HIV, and 58% of PLHIV were likely or very likely to retest for HIV in the coming year. Educating providers and men living with HIV could reduce retesting among PLHIV.

Policies and Practices Facilitating Access to and Uptake of HIV Testing Services among Adolescents in Sub-Sahara Africa: A Narrative Review.

Expanding access to HIV testing services and linking newly diagnosed positive adolescents to antiretroviral therapy is critical to epidemic control. However, testing coverage and treatment initiation rates continue to lag behind adult counterparts. This article synthesizes evidence on facilitative policies and service delivery practices focused on adolescents to inform programming. Our narrative review found that national policies are growing more adolescent-inclusive but barriers around the age of consent, waiver frameworks and dissemination constrain translate into practice. Facility-based provider-initiated testing through integrated sexual health services and dedicated youth centres demonstrates uptake effectiveness if confidentiality and youth-friendly adaptations are assured. Supportive policies, youth-responsive adaptations across testing models and strengthening age-disaggregated monitoring are vital to improving adolescents' engagement across the HIV testing and treatment cascade. Further implementation research is imperative to expand the reach of adolescent HIV testing in sub-Saharan Africa.

Investigating inequalities in HIV testing in sub-Saharan Africa: spatial analysis of cross-sectional population-based surveys in 25 countries

ObjectivesWe aim to explore spatial variations in socioeconomic inequalities in HIV testing uptake in sub-Saharan Africa (SSA) at different geographical scales to identify potential geographical hotspots of inequalities. Additionally, to...

Piloting Gain and Loss-Framed PrEP and Childbearing Messaging to Promote HIV Testing in Uganda: Perspectives from Couples and Providers

Fears of relationship dissolution and the inability to bear healthy children remain barriers to HIV testing in sub-Saharan Africa. Pre-exposure prophylaxis (PrEP) carries both clinical and symbolic benefits that counter these fears. We conducted a pilot messaging intervention through Uganda’s assisted partner notification (APN) program, where providers assist HIV-positive index clients in notifying sexual partners and encourage testing. We randomized providers at three clinics to implement phone scripts over two months with (1) gain-framed or (2) loss-framed information about PrEP and childbearing; or (3) usual care. In 23 in-depth interviews with providers, index clients, and partners, five major themes emerged on intervention acceptability and feasibility: (1) value of PrEP and childbearing messaging in APN; (2) value of this messaging coming earlier in APN; (3) overall preference for gain-framed messages; (4) need to tailor timing of messaging; and (5) need for messaging outside of APN. Register data (109 index clients, 145 partners) indicated most index clients (95%) wanted their potential conception partners informed about PrEP. Preliminary trends suggest the intervention sites outperformed usual care in testing rates among potential conception partners. Messaging that highlights PrEP and safe childbearing may be a promising new communication strategy to promote HIV testing.

Mobile Phones and HIV Testing: Multicountry Instrumental Variable Analysis From Sub-Saharan Africa.

Sub-Saharan Africa has been a technological hothouse when it comes to mobile phone technology adoption. However, evidence on the role played by mobile technology on infectious disease prevention has been mostly limited to experimental studies. This observational study investigates the role of mobile phone connectivity on HIV testing in sub-Saharan Africa. We make use of the novel and comprehensive OpenCelliD cell tower database and Demographic and Health Survey geocoded information for over 400,000 women in 29 sub-Saharan African countries. We examine, through ordinary least square and instrumental variable regressions, whether women's community distance from the closest cell tower influences knowledge about HIV testing facilities and the likelihood of ever being tested for HIV. After finding a negative and significant impact of distance to the nearest cell tower on knowledge of HIV testing facility (-0.7 percentage points per unit increase in distance) and HIV testing (-0.5 percentage points per unit increase), we investigate the mechanisms through which such effects might occur. Our analysis shows that distance to a cell tower reduces HIV-related knowledge (-0.4 percentage points per unit increase) as well as reproductive health knowledge (-0.4 percentage points per unit increase). Similar results are observed when the analysis is performed at community level. Results suggest that the effect of mobile phone connectivity is channeled through increased knowledge of HIV, sexually transmittable infections, and modern contraceptive methods. Further analysis shows that cell phone ownership has an even larger impact on HIV testing and knowledge. This paper adds to the recent literature on the impact of mobile-based HIV prevention schemes by showing through large-scale analysis that better mobile network access is a powerful tool to spread reproductive health knowledge and increase HIV awareness.

A Systematic Review of HIV Testing Implementation Strategies in Sub-Saharan African Countries.

HIV/AIDS remains a looming presence in public health across the world, particularly in Sub-Saharan Africa. The HIV Care Cascade hinges on testing and knowledge of HIV status. Though significant advances have been made in diagnosing people living with HIV (PLHIV), limitations in understanding which strategies are best suited to certain regions or populations have contributed to the uneven distribution in the success of various HIV testing strategies. Here, we present a conceptual framework that outlines effective HIV testing strategies for four target groups. This framework is based on a systematic literature review of articles published from January 1st, 2008, to December 31st, 2019. The effectiveness of HIV testing strategies depends on various factors including the setting, type of test and service providers. Multiple strategies are needed to reach the UNAIDS target of 95% of individuals knowing their HIV status. Expansion of community-based approaches, self-testing and HIV testing services in antenatal care will further improve the state of HIV testing in Sub-Saharan Africa.

Prenatal care coverage and correlates of HIV testing in sub-Saharan Africa: Insight from demographic and health surveys of 16 countries.

Prenatal screening of pregnant women for HIV is central to eliminating mother-to-child-transmission (MTCT) of HIV. While some countries in sub-Saharan Africa (SSA) have scaled up their prevention of MTCT programmes, ensuring a near-universal prenatal care HIV testing, and recording a significant reduction in new infection among children, several others have poor outcomes due to inadequate testing. We conducted a multi-country analysis of demographic and health surveys (DHS) to assess the coverage of HIV testing during pregnancy and also examine the factors associated with uptake. We analysed data of 64,933 women from 16 SSA countries with recent DHS datasets (2015-2018) using Stata version 16. Adjusted and unadjusted logistic regression models were used to examine correlates of prenatal care uptake of HIV testing. Statistical significance was set at p<0.05. Progress in scaling up of prenatal care HIV testing was uneven across SSA, with only 6.1% of pregnant women tested in Chad compared to 98.1% in Rwanda. While inequality in access to HIV testing among pregnant women is pervasive in most SSA countries and particularly in West and Central Africa sub-regions, a few countries, including Rwanda, South Africa, Zimbabwe, Malawi and Zambia have managed to eliminate wealth and rural-urban inequalities in access to prenatal care HIV testing. Our findings highlight the between countries and sub-regional disparities in prenatal care uptake of HIV testing in SSA. Even though no country has universal coverage of prenatal care HIV testing, East and Southern African regions have made remarkable progress towards ensuring no pregnant woman is left untested. However, the West and Central Africa regions had low coverage of prenatal care testing, with the rich and well educated having better access to testing, while the poor rarely tested. Addressing the inequitable access and coverage of HIV testing among pregnant women is vital in these sub-regions.

Autonomy in HIV testing: a call for a rethink of personal autonomy in the HIV response in sub-Saharan Africa.

The author reviews various conceptions of autonomy to show that humans are actually not autonomous, strictly speaking. He argues for a need to rethink the personal autonomy approaches to HIV testing in sub-Saharan Africa (SSA) countries. HIV/AIDS has remained a leading cause of disease burden in SSA. It is important to bring this disease burden under control, especially given the availability of current effective antiretroviral regimens in low- and middle-income countries. In most SSA countries the ethic or value of personal autonomy or self-determination is promoted as primary in HIV testing decision-making. SSA policymakers have an ontological and moral duty to adopt HIV testing policies that reflect human and medical realities, relationships, local contexts, and respect human rights for both individuals and others who are affected by HIV in society. Without rethinking the value of autonomy in HIV testing decision-making, the article cautions that attainment of the Sustainable Development Goal (SDG) 3 and the UNAIDS fast-track strategy that explicitly call to end the epidemic by 2030 will not be feasible for SSA.

Temporal trends in socioeconomic inequalities in HIV testing: an analysis of cross-sectional surveys from 16 sub-Saharan African countries

Overall increases in the uptake of HIV testing in the past two decades might hide discrepancies across socioeconomic groups. We used data from population-based surveys done in sub-Saharan Africa to quantify socioeconomic inequalities in uptake of HIV testing, and to establish trends in testing uptake in the past two decades. We analysed data from 16 countries in sub-Saharan Africa where at least one Demographic and Health Survey was done before and after 2008. We assessed the country-specific and sex-specific proportions of participants who had undergone HIV testing in the previous 12 months across wealth and education groups, and quantified socioeconomic inequalities with both the relative and slope indices of inequalities. We assessed time trends in inequalities, and calculated mean results across countries with random-effects meta-analyses. We analysed data for 537 784 participants aged 15-59 years (most aged 15-49 years) from 32 surveys done between 2003 and 2016 (16 before 2008, and 16 after 2008) in Cameroon, Côte d'Ivoire, DR Congo, Ethiopia, Guinea, Kenya, Lesotho, Liberia, Malawi, Mali, Niger, Rwanda, Sierra Leone, Tanzania, Zambia, and Zimbabwe. A higher proportion of female participants than male participants reported uptake of HIV testing in the previous 12 months in five of 16 countries in the pre-2008 surveys, and in 14 of 16 countries in the post-2008 surveys. After 2008, in the overall sample, the wealthiest female participants were 2·77 (95% CI 1·42-5·40) times more likely to report HIV testing in the previous 12 months than were the poorest female participants, whereas the richest male participants were 3·55 (1·85-6·81) times more likely to report HIV testing than in the poorest male participants. The mean absolute difference in uptake of HIV testing between the richest and poorest participants was 11·1 (95% CI 4·6-17·5) percentage points in female participants and 15·1 (9·6-20·6) in male participants. Over time (ie, when pre-2008 and post-2008 data were compared), socioeconomic inequalities in the uptake of HIV testing in the previous 12 months decreased in male and female participants, whereas absolute inequalities remained similar in female participants and increased in male participants. Although relative socioeconomic inequalities in uptake of HIV testing in sub-Saharan Africa has decreased, absolute inequalities have persisted or increased. Greater priority should be given to socioeconomic equity in assessments of HIV-testing programmes. INSERM-ANRS (France Recherche Nord and Sud Sida-HIV Hépatites).

Women's Empowerment and HIV Testing Uptake: A Meta-analysis of Demographic and Health Surveys from 33 Sub-Saharan African Countries.

ABSTRACTBackground:There is a growing body of evidence suggesting that women’s empowerment can help achieve better health behaviours and outcomes. However, few have looked at the impact of women’s empowerment on HIV testing in Sub-Saharan Africa (SSA). This study investigated the association between women’s empowerment and HIV testing among women in 33 countries across SSA.Methods:Cross-sectional data from the most recent Demographic and Health Surveys (2005-2018) of 33 countries in SSA were used. Confounder adjusted logistic regression analysis was completed separately for each of the 33 DHS datasets to produce the adjusted Odds Ratio (OR) for the association between women empowerment and HIV testing. The regression analysis strictly accounted for the three design elements (weight, cluster and strata) to produce an estimate representative of the respective countries. Finally, an Individual Participant Data (IPD) meta-analysis approach was used to statistically pool the effect of women empowerment on HIV testing.Results:There was a wide variation in the percentage of women who were empowered among the countries studied, with only a few countries such as South Africa, Angola and Ghana having a high prevalence of negative attitudes toward wife beating. HIV testing was higher in Angola, Lesotho, Uganda and South Africa. While participation in one or two of the three decisions had been marginally associated with lower odds of HIV testing across the SSA regions (0.89; 95%CI: 0.83, 0.97); the corresponding prediction interval crossed the null. Being involved in the three decisions (0.92; 95%CI: 0.84, 1.00) and disagreement to wife-beating (0.99; 95%CI: 0.94, 1.05) had no statistical relationship with HIV testing uptake.Conclusion and Global Health Implications:The two indirect indicators of women empowerment could not predict HIV testing uptake. Further studies are recommended to establish the nature of the relationship between HIV testing and women’s empowerment that is measured through standard tools.

A Commitment to HIV Diagnostic Accuracy - a comment on "Towards more accurate HIV testing in sub-Saharan Africa: a multi-site evaluation of HIV RDTs and risk factors for false positives 'and' HIV misdiagnosis in sub-Saharan Africa: a performance of diagnostic algorithms at six testing sites".

As part of the global response to the HIV/AIDS epidemic, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) is committed to the provision of high‐quality services and ensuring testing accuracy. Two recently published papers focusing on HIV testing and misdiagnosis in sub‐Saharan Africa by Kosack et al. report on evaluations of HIV rapid diagnostic tests (RDTs) and found lower than expected specificity and sensitivity on some tests when used in certain geographic locations. The magnitude of PEPFAR's global HIV response has been possible due to the extensive use of RDTs, which have made HIV diagnosis accessible all over the world. We take the opportunity to address concerns raised about the potential implications that these findings could have on real‐world HIV testing accuracy. PEPFAR supported countries adhere to the normative guidance by World Health Organization (WHO) supporting algorithms which require sequential positive tests for diagnostic accuracy. An analysis of Médecins Sans Frontières (MSF) RDT site‐specific data applied to PEPFAR in‐country protocols demonstrate a variation in the diagnostic accuracy of the testing algorithms, but with a very small population‐level effect. The data demonstrate, with the use of these algorithms, that the RDT outcomes found in the study by Kosack et al. would be largely mitigated and would not be expected to have a significant impact on diagnostic accuracy and overall programming in most countries. Avoiding any misdiagnosis is a priority for PEPFAR, and it remains vital to gain a deeper understanding of the causes and the extent of diagnostic errors and any misclassification. Extensive quality control mechanisms and continued research are essential. With a focus on epidemic control and ensuring diagnostic accuracy, PEPFAR recommends that all countries use WHO pre‐qualified RDTs within the recommended strategies and algorithms for HIV testing. We also support validation of HIV testing algorithms using in‐country specimens to determine optimal performance, and the reverification testing of all people diagnosed with HIV prior to starting treatment as an essential quality assurance measure.

What Role Do Masculine Norms Play in Men's HIV Testing in Sub-Saharan Africa?: A Scoping Review.

Men living with HIV/AIDS in sub-Saharan Africa are less likely to test for HIV than women. We conducted a scoping review in May of 2016 to identify how masculine norms influence men's HIV testing in sub-Saharan Africa. Our review yielded a total of 13 qualitative studies from 8 countries. Masculine norms create both barriers and facilitators to HIV testing. Barriers included emotional inexpression, gendered communication, social pressures to be strong and self-reliant, and the fear that an HIV positive result would threaten traditional social roles (i.e., husband, father, provider, worker) and reduce sexual success with women. Facilitators included perceptions that HIV testing could restore masculinity through regained physical strength and the ability to re-assume the provider role after accessing treatment. Across sub-Saharan Africa, masculinity appears to play an important role in men's decision to test for HIV and further research and interventions are needed to address this link.

Scaling up Pediatric HIV Testing by Incorporating Provider-Initiated HIV Testing Into all Child Health Services in Hurungwe District, Zimbabwe.

Practical ways are needed to scale-up pediatric HIV testing in sub-Saharan Africa, where testing is usually limited to HIV-exposed children in maternal and child health clinics. We implemented an enhanced pediatric HIV testing program in 33 health facilities in Zimbabwe by integrating HIV testing into all pediatric health services. We collected individual data on children tested by having health care workers complete a program-specific child health booklet. We compared numbers of children tested before and during the program using routinely collected aggregate program data reported by health facilities. A total of 12,556 children aged 0-5 years were recorded in child health booklets; 9431 (75.1%) had information on HIV testing, of whom 7326 (77.7%) were tested; 7167 had test results of whom 122 (1.7%) were HIV-infected. Among children seen in outpatient clinics, 82.1% were tested compared with 66.5% tested among children seen in maternal/child health clinics. Of the 122 HIV-infected children identified, 77 (63.1%) could be missed under existing pediatric testing guidelines. The number of HIV-infected children identified during the 6-month program increased by 55% compared with the prior 6-month period (RR = 1.55, 95% CI: 1.22 to 1.96). Factors independently associated with HIV infection included being malnourished (adjusted odds ratio [AOR] = 7.7, 95% CI: 2.1 to 28.6), being exposed to TB (AOR = 8.1, 95% CI: 2.0 to 32.2), and having an HIV-infected mother (AOR = 41.6, 95% CI: 15.9 to 108.8). Integrating HIV testing into all pediatric health services is feasible and can assist in identifying HIV-infected children who could be missed in current testing guidelines.

‘If I had not taken it [HIVST kit] home, my husband would not have come to the facility to test for HIV’: HIV self-testing perceptions, delivery strategies, and post-test experiences among pregnant women and their male partners in Central Uganda

ABSTRACTBackground: HIV self-testing (HIVST) can improve HIV-testing rates in ‘hard-to-reach’ populations, including men. We explored HIVST perceptions, delivery strategies, and post-test experiences among pregnant women and their male partners in Central Uganda.Methods: This was a qualitative study implemented as part of a pilot, cluster-randomized oral HIVST intervention trial among 1,514 pregnant women attending antenatal care services at three health facilities in Central Uganda. The qualitative component of the study was conducted between February and March 2017. We conducted 32 in-depth interviews to document women and men’s perceptions about HIVST, strategies used by women in delivering the kits to their male partners, male partners’ reactions to receiving kits from their female partners, and positive and negative social outcomes post-test. All interviews were audio-recorded, transcribed verbatim, and analyzed manually following a thematic framework approach.Results: Women were initially anxious about their male partners’ reaction if they brought HIVST kits home, but the majority eventually managed to deliver the kits to them successfully. Women who had some level of apprehension used a variety of strategies to deliver the kits including placing the kits in locations that would arouse male partners’ inquisitiveness or waited for ‘opportune’ moments when their husbands were likely to be more receptive. A few (three) women lied about the purpose of the test kit (testing for syphilis and other illnesses) while one woman stealthily took a mucosal swab from the husband. Most men initially doubted the ability of oral HIVST kits to test for HIV, but this did not stop them from using them. Both men and women perceived HIVST as an opportunity to learn about each other’s HIV status. No serious adverse events were reported post-test.Conclusion: Our findings lend further credence to previous findings regarding the feasibility of female-delivered HIVST to improve male partner HIV testing in sub-Saharan Africa. However, support for women in challenging relationships is required to minimize potential for deception and coercion.

Antenatal HIV Testing in Sub-Saharan Africa During the Implementation of the Millennium Development Goals: A Systematic Review Using the PEN-3 Cultural Model.

This study systematically explored the barriers and facilitators to routine antenatal HIV testing from the perspective of pregnant women in sub-Saharan Africa during the implementation period of the Millennium Development Goals. Articles published between 2000 and 2015 were selected after reviewing the title, abstract, and references. Twenty-seven studies published in 11 African countries were eligible for the current study and reviewed. The most common barriers identified include communication with male partners, patient convenience and accessibility, health system and health-care provider issues, fear of disclosure, HIV-related stigma, the burden of other responsibilities at home, and the perception of antenatal care as a "woman's job." Routine testing among pregnant women is crucial for the eradication of infant and child HIV infections. Further understanding the interplay of social and cultural factors, particularly the role of women in intimate relationships and the influence of men on antenatal care seeking behaviors, is necessary to continue the work of the Millennium Development Goals.

Overcoming resistance to HIV testing in sub-Saharan Africa

Personal awareness of HIV serostatus is an essential requirement for effective prevention and treatment, but despite decades of concerted efforts to promote HIV testing, less than 45% of people with HIV in sub-Saharan Africa know their status. 1 Staveteig S Wang S Head S Bradley S Nybro E Demographic patterns of HIV testing uptake in sub-Saharan Africa. ICF International, Calverton, Maryland, USA2013 Google Scholar Major barriers to testing include stigma and discrimination, inaccessibility of services, and low awareness of the benefits of testing and early treatment. Strategies to increase HIV testing have moved beyond fixed clinics to include community-based services, including mobile and home-based HIV testing, and self-testing. These strategies have increased the proportion of people being tested, reduced risk behaviour, 2 Fonner VA Denison J Kennedy CE O'Reilly K Sweat M Voluntary counseling and testing (VCT) for changing HIV-related risk behavior in developing countries.

Systematic review of strategies to increase men's HIV-testing in sub-Saharan Africa.

This systematic review summarizes evidence on the effectiveness of strategies to increase men's HIV-testing in sub-Saharan Africa. Medline, EmBase, Africa-Wide Information and Global Health were searched. Cluster and individually randomized trials evaluating interventions to increase the proportion of adults (≥ 15 years) testing for HIV were eligible if they were conducted in sub-Saharan Africa, included men in the study population, and reported HIV-testing data by sex. References were independently screened. Of the 1852 references, 15 papers including 16 trials were eligible. Trials were judged too heterogeneous to combine in meta-analysis. Three interventions invited men to attend antenatal care-based HIV-testing via pregnant partners, of which two showed a significant effect on partner-testing. One intervention invited men to HIV-test through pregnant partners and showed an increase in HIV-testing when it was offered in bars compared with health facilities. A trial of notification to partners of newly diagnosed HIV-positive patients showed an increase in testing where notification was by healthcare providers compared with notification by the patient. Three interventions reached men already at health facilities and eight reported the effects of community-based HIV testing. Mobile-testing had a significant effect on HIV-testing compared with standard voluntary counselling and testing. Home-based testing also had a significant effect, but reached smaller numbers of men than mobile-testing. Interventions to encourage HIV-testing can increase men's levels of HIV testing. Community-based programmes in particular had a large effect on population levels of HIV-testing. More data on costs and potential population impact of these approaches over different time-horizons would aid policy-makers in planning resource allocation to increase male HIV-testing.

Is the absolute requirement for informed consent before HIV testing a barrier to public health? A case report and management challenges

Clinicians in sub-Saharan Africa are faced with a major challenge of parental refusal to test their children for HIV. We present a case of a nine-month-old child with a clinical presentation suggestive of HIV infection whose mother persistently declined HIV testing of the child or herself. The case illustrates the difficulties faced by the clinicians caring for the child in an isolated location in West Africa. While not eliminating these difficulties, an opt-out approach to paediatric HIV testing in sub-Saharan Africa may increase the proportion of children who access treatment when they need it, particularly when this is backed by the development of more effective national and regional clinical and legislative frameworks for HIV testing in children.
