Preventive measures against HIV among Uganda's youth: Strategies, implementation, and effectiveness.

Preventing HIV among Uganda's youth is a critical public health priority due to the high prevalence of HIV/AIDS and the disproportionate burden of new infections among young people. This paper examines the preventive measures implemented to combat HIV/AIDS among Uganda's youth, focusing on strategies, implementation efforts, and the effectiveness of interventions. Comprehensive sexuality education programs have been implemented in schools and communities to provide young people with accurate information on HIV transmission, prevention methods, and reproductive health. Condom distribution and promotion campaigns target sexually active youth, while HIV testing and counseling services aim to reach youth in various settings, including health facilities and community outreaches. The implementation of HIV prevention strategies involves collaboration among government agencies, NGOs, healthcare providers, educators, and community leaders. Efforts are made to ensure that prevention programs are culturally appropriate, evidence-based, and responsive to the needs of young people. Despite progress in HIV prevention, challenges persist, including knowledge gaps, stigma, gender inequalities, and socio-economic factors. Continuous monitoring and evaluation are essential to assess the impact of interventions and identify areas for improvement. Recommendations include increasing funding for HIV prevention programs, strengthening policy frameworks, enhancing access to youth-friendly health services, integrating comprehensive sexuality education into school curricula, and fostering community engagement. By addressing these recommendations, Uganda can strengthen its HIV prevention efforts and reduce the incidence of HIV/AIDS among its youth population, ultimately contributing to improved health outcomes and well-being.

Knowledge and utilization of HIV/AIDs preventive measures among intra-city commercial drivers in Kano State, Nigeria

Background: Intracity commercial drivers play a vital role in transportation systems in many urban centers. However, their occupation puts them at risk for HIV infection due to various factors. Despite their increased vulnerability, intracity commercial drivers face significant challenges in accessing HIV prevention, testing, and treatment services. Method: This was an observational community-based cross-sectional descriptive study conducted among intracity commercial drivers in Kano State, Nigeria through multistage sampling technique. Result: the mean age and standard deviation of respondents was 42.0 ± 11.3. About two-third (67.7%) had good aggregate knowledge score and more than half (57.4%) of the study participant had good uptake and utilization of HIV/AIDs preventive services. After adjusting for the confounding effects using logistic regression analysis; educational status of secondary school (AOR=2.25, 95% CI=1.21–13.25) and post-secondary (AOR=4.10,95%CI=2.22-17.88), monthly income of between N50,0001 – N100,000.00 (AOR=2.02, 95%CI=1.74-19.33) and >N100,000.00 (AOR=4.01, 95%CI=3.11-27.33), working experience of 11 – 20 years (AOR=3.25, 95%CI= 1.16-22.56) and >20 years (AOR=6.05, 95%CI= 3.03-26.77) and good aggregate knowledge scores on HIV/AIDs preventive measures (AOR=4.02 (2.13 – 14.55), 95%CI=2.13-14.55) remained significant predictors of uptake/utilization of HIV/AIDs preventive measures. Conclusion: All agencies responsible for HIV/AIDs control and their partners should take appropriate measures including various strategies to educate this occupational group on sexuality and reproductive health. Also, the establishment of STI clinics in strategic locations, as well as making condoms available, accessible, affordable, and acceptable for use by this group of people in our society, should all be part of the prevention strategy.

How can HIV self-testing facilitate increased access to HIV testing among multiply marginalised populations? Perspectives from GBMSM and trans women in England and Wales

Background HIV self-testing (HIVST) may facilitate marginalised populations’ uptake of HIV testing, but whether the extent of marginalisation challenges individual uptake of HIVST remains under-researched. We aim to explore the perspectives of multiply marginalised cis-gender gay, bisexual and other men who have sex with men (GBMSM) and trans women on whether HIVST might increase their uptake of HIV testing. Methods We reanalysed qualitative interview data from SELPHI (the UK’s largest HIVST randomised trial) collected between 2017 and 2020 from marginalised populations, defined as people self-identifying as non-heterosexual, transgender, non-White ethnicity and/or with low educational attainment. Thirty-eight interviews with multiply marginalised individuals were thematically examined using the framework method. We specifically focussed on kit usability (a function of the interaction between blood-based HIVST kits and users), perspectives on how HIVST can improve access to HIV testing and suggestions on need-based scale-up of HIVST. Results HIVST kits were considered usable and acceptable by multiply marginalised GBMSM and trans women. The majority of interviewees highlighted multi-levelled barriers to accessing HIV testing services due to structural and social marginalisation. Their multiply marginalised identities did not impede HIVST uptake but often form motivation to self-test. Three potential roles of HIVST in the HIV testing landscape were identified: (1) alternation of HIVST and facility-based testing, (2) integration of HIVST into sexual health services and (3) substituting facility-based testing with HIVST in the future. Perceived beneficiaries of HIVST included trans communities, individuals with undisclosed sexuality and people with physical disabilities. Discussion HIVST can facilitate marginalised populations’ access and uptake of HIV testing by alternating with, integrating into and substituting for facility-based services in the UK. Marginalised identities did not present challenges but rather opportunities for person-centred scale-up of HIVST. Future implementation programmes should ensure equitable access to HIVST among trans people, men unable to disclose their sexuality, and perhaps people with physical disabilities.

HIV testing services and HIV self-testing programming within emergency care in Kenya: a qualitative study of healthcare personnel to inform enhanced service delivery approaches

ABSTRACT In Kenya, persons insufficiently engaged in HIV Testing Services (HTS) are often treated in emergency departments (ED). There are limited data from healthcare workers on ED-HTS. A qualitative study was completed to understand challenges and facilitators for ED-HTS and HIV self-testing (HIVST). Data were collected via six focus groups of healthcare workers. Data were inductively analyzed and mapped to the Capability–Opportunity–Motivation Behavioral Model. Focus groups were completed with 49 healthcare workers: 18 nurses, 15 HIV counselors, 10 physicians and 6 administrators. HTS challenges included staff burdens, resources access, deficiencies in systems integration and illness severity. HTS facilitators included education of healthcare workers and patients, services coordination, and specific follow-up processes. HIVST challenges included accuracy concerns, follow-up barriers and psychosocial risks. HIVST facilitators were patient autonomy and confidentiality, resource utilization and ability to reach higher-risk persons. Mapping to the Capability–Opportunity–Motivation Behavioral Model interventions within the domains of knowledge, decision processes, environmental aspects, social influences and professional identities could support enhanced ED-HTS with integrated HIVST delivery. This study provided insights into challenges and facilitators on ED-HTS and identifies pragmatic approaches to improve healthcare workers’ behaviors and abilities to provide services to persons already in contact with healthcare.

Relationship Between Psychotherapy and Mitigation of Self-Stigmitization Among Adult Persons Living with HIV in Nairobi City, Kenya

Human Immunodeficiency virus (HIV) has caused a lot of suffering ever since the first case was reported. To date there are about 80,000,000 People living with HIV (PLWH). Although the rate of new infections has reduced, the effects remain far reaching, especially in Sub-Sahara Africa. Apprehension associated with HIV often scares many from finding out their HIV standing, considering restraint methods, avoiding risky conducts, and uplifting of PLWH endeavours. Many studies focused on HIV testing and counselling services which is for now mainly service provider driven. The drive of this study was showing the relationship between psychotherapy and mitigation of self-stigmatization (SS) among Adult PLWH in Embakasi East Sub-County (herein denoted Embakasi East), Nairobi City, County (herein denoted Nairobi City), Kenya; Social Cognitive Theory guided this study, employing descriptive research design on a target population of 3,886 PLWH registered for ART treatment at 7 public health centres in Embakasi East, Nairobi City. Cochran’s sample size formula was applied in determining the suitable sample size of 246 that was confirmed by the sampling table. Purposive sampling was used to select both the public health centres and the informants from each centre. Proportionate random sampling assisted in picking participants (both male and female), then random sampling was used to construct the sample. The sample of 246 (74 males and 172 females) was drawn, with 6 informants. Informants were interviewed and questionnaires completed by PLWH. In the analysis of the data, descriptive statistics, mainly frequencies, percentages and mean were applied on facts while thematic analysis on qualitative data. The study results showed that SS was very prevalent, caused by the respondents themselves and those around them. They acknowledged being hated, them hating themselves and did not want their HIV status known. Just a few had utilized psychotherapy service, who agreed that they were relieved a lot of pain they were undergoing, and they recommended it to others. The study recommended that authorities need to consider promoting and committing resources for psychotherapy as a solution to SS among PLWH, invest more in advocacy work, and invigorating sensitization among families on their role in supporting PLWH being

Barriers and enablers that influence the uptake of HIV testing among heterosexual migrants in the Netherlands.

Heterosexual migrant men and women in the Netherlands often face barriers to accessing health services, including HIV testing, that may lead to late-stage HIV diagnoses. This study explored factors of influence in the usage of HIV testing among heterosexual migrants. Qualitative evaluation with semi-structured interviews at the Amsterdam-based AIDS Healthcare Foundation (AHF) Checkpoint and one focus group discussion (FGD) conducted during June-July 2023 with 19 participants: interviews with 12 heterosexual migrants from low- or middle-income countries (LMICs) and FGD (n = 5) and interviews (n = 2) with 7 key informants from the (public) health sector. Recorded interviews were transcribed and thematically analyzed, using the framework of Andersen's Expanded Behavioral Model of Health Services Use. In total, 55 themes emerged from the interviews and the FGD. Examples include insufficient availability of information on HIV and testing services, and difficulty in accessing these services (e.g. the barrier of the online appointment system of the Centre for Sexual Health (CSH)). HIV test participants expressed free, rapid testing, no appointment required, and a positive experience during their HIV test as enablers to test in the future. Results from key informants showed that poor health literacy and lack of clarity on the healthcare system's guidelines were barriers for heterosexual migrants in accessing information on HIV and testing services. It also revealed past initiatives and interventions that were successful in reaching at-risk groups such as the integration of HIV testing into sexually transmitted infection (STI) testing, but that were subsequently discontinued due to financial constraints. Factors contributing to a low HIV test uptake were participants' perception of limited accessibility of CSH facilities, insufficient available information on HIV (testing) services, and low perception of HIV risk. Unclear policies on accessing HIV/STI testing services at CSHs, and potential missed opportunities for HIV testing at general practitioners were contributing factors identified by key informants.

Strengths and Weaknesses of HIV Partner Notification Implementation in Iran.

HIV partner notification is a key intervention to facilitate access to HIV testing and treatment. This qualitative study investigated the strengths and weaknesses of the HIV partner notification program in Iran. Additionally, it provides comprehensive recommendations to mitigate potential harms and maximize the benefits of partner notification services. Using purposive sampling, 15 participants, including policymakers, service providers, and researchers in the field of HIV, were recruited from nine provinces between September and December 2023. The qualitative content analysis was conducted using the Graneheim and Lundman approach. Several strengths were reported for the HIV partner notification program, including alignment with international guidelines, use of trained counselors, integration with current HIV testing guidelines being used by HIV testing centers funded by the Ministry of Health, and a well-developed monitoring and evaluation plan at the facility, provincial, and national levels. Notable weaknesses of the program included a lack of a detailed implementation plan overall and for some key populations at high risk for HIV, such as female sex workers, lack of integration of the program with HIV testing services provided in hospitals and HIV centers funded by the Welfare Organization in Iran, lack of a simple quality checklist for monitoring and evaluation of the program. To increase the coverage and quality of the HIV partner notification program in Iran, a more detailed implementation plan, a simple quality checklist, and more targeted advocacy and training programs are needed.

Gaps in HIV Pre-exposure Prophylaxis Acceptance: Findings from an Outpatient HIV Testing Service in Italy

Background: The aim of this study is to assess the acceptability of HIV pre-exposure prophylaxis (PrEP) among individuals eligible for prophylaxis. Setting: Retrospective study of individuals receiving their first HIV test at the Infectious Diseases Unit of IRCCS San Raffaele Scientific Institute, Milan, Italy. Methods: People i) who received their first HIV test (baseline date) between January 2018 (availability of PrEP in Italy) and December 2023 (data lock), ii) with an indication for PrEP based on condomless sex were included; those already on PrEP were excluded. Individuals with a negative HIV test result were offered PrEP counselling and prescription according to guidelines. Characteristics of people who accepted or declined HIV PrEP were compared using Mann-Whitney or Chi-square tests, as appropriate. Results: A total of 2627 people were tested for HIV: 175 (6.6%) were diagnosed with HIV. Of the 2452 people with negative HIV test results, 2165 (88.3%) were men; median age was 34.3 years (interquartile range, IQR=28.7-42.4). Sexually transmitted infections (STIs) were detected in 478/2452 (19.5%), most commonly gonorrhoea (206/2452, 8.4%). Overall, 982/2452 (40.0%) people accepted PrEP, including only three women. Non-acceptance was higher among women (p<0.001) and non-Caucasians (p<0.001). Of those who did not accept PrEP, 260 (17.7%) were diagnosed with at least one STI at the time of HIV testing. Conclusion: Low PrEP acceptance was observed, particularly among women and people of non-Caucasian origin. Non-acceptance of PrEP was also observed among individuals diagnosed with an STI.

Perceived risks and benefits of telePrEP interventions: An interview study with rural sexual minority men in Texas.

Many rural areas lack brick-and-mortar HIV prevention resources despite the increasing rates of HIV. Although online HIV pre-exposure prophylaxis (PrEP) programs can potentially increase uptake among rural sexual minority men (SMM), their attitudes and preferences regarding telehealth-based PrEP (telePrEP) programming are uncertain. This qualitative study examined rural SMM's perceived risks and benefits of participating in a hypothetical telePrEP program. Twenty rural SMM living in Texas completed a semi-structured online videoconferencing interview between April 12 and June 14, 2023. Data were analyzed with reflexive thematic analysis. Four themes were constructed: (1) telePrEP interventions increase accessibility but completely online services might be inadequate; (2) telePrEP and mail-order interventions are convenient but face challenges; (3) telePrEP interventions need to address confidentiality and privacy within the context of the sociopolitical climate; and (4) telePrEP interventions need to address trustworthiness and transparency. Overall, our results indicate that rural SMM perceive telePrEP interventions that provide at-home and telehealth PrEP, HIV testing, and HIV care services as beneficial. However, overall utility and acceptability depend on perceptions of privacy, confidentiality, trustworthiness, and transparency. Given the HIV prevention and treatment service deserts in which many rural SMM live, telePrEP interventions must purposefully demonstrate how their operations and data will remain safe and secure. Further work should explore contextual or situational factors that influence the willingness and acceptability of rural SMM to participate in online HIV prevention intervention research studies.

Leveraging HIV self-testing to achieve the UNAIDS 2025 targets in the South and Southeast Asia region.

The South and Southeast Asia region has the second-highest number of people living with HIV globally. Despite progress in reducing HIV incidence and AIDS-related deaths, the region still has a long way to go in achieving the Joint United Nations Programme on HIV and AIDS (UNAIDS) 95-95-95 HIV testing, treatment and viral suppression targets. HIV self-testing (HIVST) is recommended by the World Health Organization as an additional approach to HIV testing. This paper provides a commentary on the implementation status, benefits, barriers and recommendations for HIVST implementation in South and Southeast Asia. Additionally, it presents perspectives from HIV testing service experts from 11 countries in the region to put forth recommendations to accelerate the implementation of HIVST in South and Southeast Asia. There is uneven progress in national HIVST policy development and implementation across the region. HIVST, as an additional testing approach, can help to enhance testing coverage, frequency and demand for follow-up HIV services among key populations. Key factors influencing the implementation and scale-up of HIVST include the degree of awareness of HIVST among general and key populations, the development and implementation of supportive national HIVST policies and the availability of public funding for HIVST. To address barriers and leverage enablers to HIVST implementation, generating evidence on cost-effectiveness and budget impact, developing multisectoral partnerships for market shaping, promoting differentiated and decentralized delivery models, and optimizing linkage to further testing and care are recommended. It is crucial to accelerate the implementation and scale-up of HIVST to differentiate and decentralize the delivery of HIV testing services in South and Southeast Asian countries. Sharing experiences among country experts is vital to foster the adoption of best practices and facilitate the trial-and-error process of HIVST implementation. Such collaborative approaches can help South and Southeast Asian countries attain the UNAIDS 95-95-95 targets, especially the first 95 on HIV diagnosis, and play a significant role in ending the global AIDS epidemic.

Uptake of HIV Testing Services among Refugee Men in Kiryandongo Refugee Settlement Camp, Mid-western Uganda

Aims: HIV testing is a critical checkpoint to late diagnosis and delayed treatment. However, utilization of HIV testing services has not yet reached the desired target, especially for men. This study aimed to determine the level of uptake of HIV testing services and the associated factors among refugee men in the Kiryandongo Refuge Settlement Camp. Study Design: Cross-sectional by mixed methods. Methodology: The study was conducted by mixed methods. A total of 422 men >18 years were selected using systematic random sampling. Interview administered semi-structured - questionnaires and informant interview guides were used to collect quantitative and qualitative data respectively. Results: The level of uptake of HIV testing services was 32%. Key factors negatively associated with the testing included social-cultural status (P=0.006, AOR=3.80) disclosure of positive results and awareness (P=0.002, AOR=0.14 and P=0.000, AOD=0.08) respectively, unemployment (P=0.015, AOR=0.17), religion (P=0.043, AOD=0.37) and multiple sexual partners (P=0.033, AOR=0.23). Conclusion: The level of uptake of HIV testing services among refugee men in the Kiryandongo refugee settlement camp is significantly lower than the national mark. Targeted testing strategies and sensitization are critical to address the negatively associated factors and inform public health policies.

Assessment of the HIV Enhanced Access Testing in the Emergency Department (HEATED) program in Nairobi, Kenya: a quasi-experimental prospective study

Background Persons seeking emergency injury care are often from higher-risk and underserved key populations (KPs) and priority populations (PPs) for HIV programming. While facility-based HIV Testing Services (HTS) in Kenya are effective, emergency department (ED) delivery is limited, despite the potential to reach underserved persons. Methods This quasi-experimental prospective study evaluated implementation of the HIV Enhanced Access Testing in Emergency Departments (HEATED) at Kenyatta National Hospital ED in Nairobi, Kenya. The HEATED program was designed as a multi-component intervention employing setting appropriate strategies for HIV care sensitization and integration, task shifting, resource reorganization, linkage advocacy, skills development and education to promote ED-HTS with a focus on higher-risk persons. KPs included sex workers, gay men, men who have sex with men, transgender persons and persons who inject drugs. PPs included young persons (18–24 years), victims of interpersonal violence, persons with hazardous alcohol use and persons never HIV tested. Data were obtained from systems-level records, enrolled injured patient participants and healthcare providers. Systems and patient-level data were collected during a pre-implementation period (6 March − 16 April 2023) and post-implementation (period 1, 1 May − 26 June 2023). Additional, systems-level data were collected during a second post-implementation (period 2, 27 June − 20 August 2023). HTS data were evaluated as facility-based HIV testing (completed in the ED) and distribution of HIV self-tests independently, and aggregated as ED-HTS. Evaluation analyses were completed across reach, effectiveness, adoption, implementation and maintenance framework domains. Results All 151 clinical staff were reached through trainings and sensitizations on the HEATED program. Systems-level ED-HTS among all presenting patients increased from 16.7% pre-implementation to 23.0% post-implementation periods 1 and 2 (RR = 1.31, 95% CI: 1.21–1.43; p < 0.001). Among 605 enrolled patient participants, facilities-based HTS increased from 5.7% pre-implementation to 62.3% post-implementation period 1 (RR = 11.2, 95%CI: 6.9–18.1; p < 0.001). There were 440 (72.7%) patient participants identified as KPs (5.6%) and/or PPs (65.3%). For enrolled KPs/PPs, facilities-based HTS increased from 4.6% pre-implementation to 72.3% post-implementation period 1 (RR = 13.8, 95%CI: 5.5–28.7, p < 0.001). Systems and participant level data demonstrated successful adoption and implementation of the HEATED program. Through 16 wk post-implementation a significant increase in ED-HTS delivery was maintained as compared to pre-implementation. Conclusions The HEATED program increased overall ED-HTS and augmented delivery to KPs/PPs, suggesting that broader implementation could improve HIV services for underserved persons already in contact with health systems.

Trends of chlamydia and gonorrhea infections by anatomic sites among men who have sex with men in south China: a surveillance analysis from 2018 to 2022

BackgroundChlamydia and gonorrhea notifications are rapidly rising in men who have sex with men (MSM). Currently, there are limited data on the prevalence of chlamydia and gonorrhea across various anatomical sites. Our study aimed to explore the prevalence, association and changing trends of urethral and rectal chlamydia and gonorrhea among MSM in Guangdong Province, China.MethodsWe analyzed data among MSM attending sexually transmitted infections (STI) clinics in the Guangdong governmental sentinel network between 2018 and 2022. Chi-square tests were used to compare the difference, Join-point regressions for analyzing changing trends, and multivariate logistic regressions for examining associated factors.ResultsWe included 4856 men in the analysis. Rectal chlamydia significantly increased from 13.8% to 26.4% over the past 5 years (average annual percentage change [AAPC] 19.2%, 95%CI 1.0-40.6, p = 0.043). After adjusting for covariates, chlamydia infection positively associated with main venue used to seek sexual partners (aOR = 2.31, 95%CI 1.17–4.55), having regular sexual partners in the past 6 months (aOR = 3.32, 95%CI 1.95–5.64), receiving HIV counselling and testing services (aOR = 2.94, 95%CI 1.67–5.17), receiving peer education (aOR = 1.80, 95%CI 1.14–2.83), infection with syphilis (aOR = 2.02, 95%CI 1.02–4.01) and infection with gonorrhea (aOR 7.04, 95% CI 3.01–16.48). Gonorrhea infection positively associated with having regular sexual partners in the past 6 months (aOR = 3.48.95%CI 1.16–10.49), and infection with chlamydia (aOR 7.03, 95% CI 2.99–16.51).ConclusionsTo conclude, our findings reveal a high prevalence of chlamydia infections among MSM, particularly in the rectal area. Comprehensive chlamydia and gonorrhea health services are necessary for MSM to improve sexual health.

Comparing the Efficacy of 2 WeChat Mini Programs in Reducing Nonmarital Heterosexual Contact by Male Factory Workers: Randomized Controlled Trial.

Male factory workers in China are vulnerable to HIV transmission. Commercial and nonmarital noncommercial contacts are the driving forces of heterosexual HIV transmission among male factory workers in China. There is a lack of effective HIV interventions for male factory workers in China. The primary objective of this randomized controlled trial was to compare the efficacy of an enhanced versus the standard version of a WeChat mini program in reducing sexual intercourse with nonregular female sex partners and female sex workers among male factory workers in Shenzhen, China. A nonblinded 2-arm parallel randomized controlled trial was conducted between December 2021 and April 2023. Participants were adult male factory workers in Shenzhen who had access to a smartphone and WeChat. Those who had oral or anal sex with a man or self-reported as HIV positive were excluded. A total of 247 participants were randomly assigned to the intervention group (n=125, 50.6%) or the control group (n=122, 49.4%); 221 (89.5%) and 220 (89.1%) completed follow-up surveys at T1 (6 months after completion of the interventions) and T2 (6 months after T1). Participants in the control group had access to the standard WeChat mini program that provided basic HIV-related knowledge and information about local free HIV testing services. Participants in the intervention group had access to the enhanced WeChat mini program. The enhanced mini program covered all the information in the standard mini program. In addition, the enhanced mini program assessed users' behaviors and invited users to watch different web-based videos on reducing nonmarital sexual contacts and promoting HIV testing based on their behavioral characteristics at months 0 and 1. The videos were developed based on in-depth interviews with male factory workers. Intention-to-treat analysis was used for outcome analyses. Multiple imputation was used to replace missing outcome values at T1 and T2. At T1, fewer participants in the intervention group reported sexual intercourse with a nonregular female sex partner in the past 6 months compared with the control group (1/125, 0.8% vs 8/122, 6.6%; relative risk=0.12, 95% CI 0.02-0.96; P=.02). However, there were no between-group differences in sexual intercourse with a nonregular female sex partner at T2 (10/125, 8% vs 14/122, 11.5%; P=.36) or sexual intercourse with a female sex worker at T1 (2/125, 1.6% vs 2/122, 1.6%; P=.98) or T2 (8/125, 6.4% vs 8/122, 6.6%; P=.96). The enhanced WeChat mini program was more effective than the standard WeChat mini program in reducing sexual intercourse with nonregular female sex partners among male factory workers in the short term but not in the longer term. Improvements should be made to the WeChat mini program before implementation. ClinicalTrials.gov NCT05811611; https://clinicaltrials.gov/study/NCT05811611.

Social network-based approaches to HIV testing: a systematic review and meta-analysis.

Social network-based testing approaches (SNAs) encourage individuals ("test promoters") to motivate sexual partners and/or those in their social networks to test for HIV. We conducted a systematic review to examine the effectiveness, acceptability and cost-effectiveness of SNA. We searched five databases from January 2010 to May 2023, and included studies that compared SNA with non-SNA. We used random-effects meta-analysis to combine effect estimates. Certainty was assessed using the GRADE approach. We identified 47 studies. SNA may increase uptake of HIV testing compared to non-SNA (RR 2.04, 95% CI: 1.06-3.95, Low certainty). The proportion of first-time testers was probably higher among partners or social contacts of test promoters using SNA compared to non-SNA (RR 1.49, 95% CI: 1.22-1.81, Moderate certainty). The proportion of people who tested positive for HIV may be higher among partners or social contacts of test promoters using SNA compared to non-SNA (RR 1.84, 95% CI: 1.01-3.35, Low certainty). There were no reports of any adverse events or harms associated with SNA. Based on six cost-effectiveness studies, SNA was generally cheaper per person tested and per person diagnosed compared to non-SNA. Based on 23 qualitative studies, SNA is likely to be acceptable to a variety of populations. Our review collated evidence for SNA to HIV testing covering the key populations and the general population who may benefit from HIV testing. We summarized evidence for the effectiveness, acceptability and cost-effectiveness of different models of SNA. While we did not identify an ideal model of SNA that could be immediately scaled up, for each setting and population targeted, we recommend various implementation considerations as our meta-analysis showed the effectiveness might differ due to factors which include the testing modality (i.e. use of HIV self-testing), type of test promoters, long or short duration of recruitment and use of financial incentives. Social network-based approaches may enhance HIV testing uptake, increase the proportion of first-time testers and those testing positive for HIV. Heterogeneity among studies highlights the need for context-specific adaptations, but the overall positive impact of SNA on HIV testing outcomes could support its integration into existing HIV testing services.

CDC-Funded HIV Testing Services Outcomes in Ending the HIV Epidemic in the U.S. (EHE) and Non-EHE Jurisdictions, 2021.

Ending the HIV Epidemic in the U.S. (EHE) aims to end the HIV epidemic by focusing on 57 jurisdictions most impacted by HIV. Using 2021 data from the National HIV Prevention Program Monitoring and Evaluation system, we calculated distributions of CDC-funded HIV tests and HIV testing services outcomes in EHE and non-EHE jurisdictions. We conducted chi-square tests and robust Poisson regression to compare differences in outcomes. Of the 1,753,873 tests conducted, a greater proportion were conducted in EHE (65.7%) versus non-EHE (34.3%) jurisdictions (p<0.001). Greater number of persons newly diagnosed were identified in EHE (n=5,861) versus non-EHE (n=2,329) jurisdictions; newly diagnosed positivity was higher in EHE (0.5%) versus non-EHE (0.4%; PR=1.31, 95% CI: 1.25-1.38) jurisdictions. Among persons newly diagnosed, there were no differences in proportion of linkage to care within 30 days in EHE jurisdictions (77.9%) versus non-EHE jurisdictions (77.1%; PR=1.01, 95% CI: 0.95-1.07). Proportion of persons newly diagnosed interviewed for partner services was lower in EHE (69.0%) versus non-EHE (84.8%; PR=0.81, 95% CI: 0.76-0.87) jurisdictions. CDC-funded HIV testing services in EHE jurisdictions conducted more HIV testing and diagnosed more persons. Jurisdictions can further expand HIV testing and related services to continue striving toward EHE goals.

Lessons learnt from assessing and improving accuracy and positive predictive value of the national HIV testing algorithm in Nigeria.

HIV testing remains an entry point into HIV care and treatment services. In 2007, Nigeria adopted and implemented a two-test rapid HIV testing algorithm of three HIV rapid test kits, following the sequence: Alere Determine (first test), UnigoldTM (second test), and STAT-PAK® as the tie-breaker. Sub-analysis of the 2018 Nigeria HIV/AIDS Indicator and Impact Survey data showed significant discordance between the first and second tests, necessitating an evaluation of the algorithm. This manuscript highlights lessons learnt from that evaluation. A two-phased evaluation method was employed, including abstraction and analysis of retrospective HIV testing data from January 2017 to December 2019 from 24 selected sites supported by the United States President's Emergency Plan for AIDS Relief programme. A prospective evaluation of HIV testing was done among 2895 consecutively enrolled and consented adults, aged 15-64 years, accessing HIV testing services from three selected sites per state across the six geopolitical zones of Nigeria between July 2020 and September 2020. The prospective evaluation was performed both in the field and at the National Reference Laboratory under controlled laboratory conditions. Stakeholder engagements, strategic selection and training of study personnel, and integrated supportive supervision were employed to assure the quality of evaluation procedures and outcomes. The algorithm showed higher sensitivity and specificity in the National Reference Laboratory compared with the field. The approaches to quality assurance were integral to the high-quality study outcomes. We recommend comparison of testing algorithms under evaluation against a gold standard. This study provides context-specific considerations in using World Health Organization recommendations to evaluate the Nigerian national HIV rapid testing algorithm.

Prevalence and predictors of HIV testing among young men in Papua New Guinea: A cross-sectional analysis of a nationally representative sample.

HIV testing is an important component of HIV prevention and serves as a gateway to other HIV-related services. However, the uptake remains suboptimal among young people, particularly in highly prevalent settings such as Papua New Guinea (PNG). This study aimed to assess the prevalence and determine the predictors of HIV testing uptake among young men aged 15-24 years in PNG. The 2016-2018 PNG Demographic and Health Survey (DHS) data was used. A total of 1,275 young men aged 15-24 years were included in the final analysis. Descriptive, bivariate, and multivariable logistic regression analyses were performed to determine independent predictors of HIV testing. Adjusted odds ratios (AORs) with 95% confidence intervals (CIs) were reported. All analyses were adjusted using survey weights to account for unequal sampling probabilities. The overall prevalence of HIV testing among young men was 17.1% (95% CI: 15-19). Of those who were tested for HIV, about one-third (32.9%) had experienced a sexual debut at age <15 years, and 33.9% inconsistently used condoms during sex. In multivariable analysis, men aged 20-24 years (AOR 1.18, 95% CI: 1.00-2.31), who owned mobile phones (AOR 1.43, 95% CI: 1.00-2.55), who were aware that consistent condom use during sex can reduce HIV risk (AOR 2.18, 95% CI: 1.18-4.04), who had paid for sex (AOR 1.75, 95% CI: 1.01-5.83), and who had two or more sexual partners (AOR 1.37, 95% CI: 1.01-3.14) had increased odds of HIV testing. However, decreased odds of HIV testing were found among men who were never married (AOR 0.51, 95% CI: 0.29-0.88), lived in rural areas (AOR 0.54, 95% CI: 0.32-0.92), and consistently used condoms during sex (AOR 0.59, 95% CI: 0.34-1.01). The findings show that HIV testing is low among young men in PNG. To increase HIV testing uptake among young men, it is crucial to implement comprehensive youth-friendly HIV/STI education and tailored sensitization programs and enable more accessible and affordable HIV testing services. Also, outreach and community-based testing programs for young men in rural and prioritized areas requiring urgent prevention interventions are feasible options in PNG.

Applying behavioural economics principles to increase demand for free HIV testing services at private doctor-led clinics in Johannesburg, South Africa: A randomised controlled trial.

Expanding free HIV testing service (HTS) access to include private clinics could increase testing rates. A donor funded programme, GP Care Cell, offered free HIV testing at selected private doctor-led clinics but uptake was low. We investigated whether HTS demand creation materials that used behavioural economics principles could increase demand for HIV testing at these clinics. We conducted a randomised controlled trial in Johannesburg, South Africa (January-April 2022) distributing brochures promoting HTS to adults in five private doctor-led clinic catchment areas. Individuals were randomised to receive three brochure types: (1) "Standard of care" (SOC) advertising a free HIV test and ART; (2) "Healthy lifestyle screening" promoted free low-cost health screenings in addition to HTS; and (3) "Recipient of care voucher" leveraged loss aversion and the endowment effect by highlighting the monetary value of free HTS. The primary outcome was presenting at the clinic following exposure to the brochures. Logistic regression compared outcomes between arms. We found that of the 12,129 brochures distributed, 658 were excluded because of errors or duplicates and 11,471 were analysed. About 59% of brochure recipients were male and 50,3% were aged 25-34 years. In total, 448 (3.9%) brochure recipients presented at the private doctor-led clinics of which 50.7% were males. There were no significant differences in clinic presentation between the healthy lifestyle screening and SOC arm (Adjusted Odds Ratio [AOR] 1.02; 95% CI 0.79-1.32), and similarly between the recipient of care voucher and SOC arm (AOR 1.08; 95% CI 0.84-1.39). Individuals were more likely to attend centrally-located clinics that had visible HTS branding (AOR = 5.30; 95% CI: 4.14-6.79). Brochures that used behavioural insights did not increase demand for HTS at private doctor-led clinics. However, consistent distribution of the brochures may have potential to increase HIV testing uptake at highly visible private doctor-led clinics.

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.
