United Nations Programme On HIV And AIDS Research Articles

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.

The Establishment Of Shelters as A New Paradigm Towards Struggling With Violence Against Women: A Literature Review.

Shelters are an important part of a full response to survivors, as stated in many international conventions, such as the 1995 Beijing Declaration and Platform for Action (BDPfA). This study aims to provide a comprehensive perspective on the establishment of shelters for women survivors of violence. This narrative review was conducted based on the Scale for the Assessment of Narrative Review Articles (SANRA). The MEDLINE, SCOPUS, Web of Science, Embase, Ovid, and EBSCO databases in English and Magiran and Scientific Information Database (SID) in Persian were searched for related documents. Also, WHO, the Joint United Nations Programme on HIV and AIDS (UNAIDS), the Centers for Disease Control and Prevention (CDC), and the United Nations Population Fund's (UNFPA) guidelines and instructions for shelter services for women and girls who have been subjected were searched up to July 31, 2023. A qualitative synthesis was carried out on the 28 eligible articles and instructions out of the 420 retrieved documents. "A "shelter" describes emergency and temporary "safe accommodation for women and children who have been subjected to or are at risk of (typically male) domestic abuse. Types of shelters include emergency shelters or safe homes, second-stage or transitional housing facilities, third-stage housing, and alternative accommodation during (and occasionally after) the period of residence. The shelter delivers a wide range of services, including health services, socio-economic services, and legal services. These principles consisted of a comprehensive perspective, quality of service, organization, funding, and the right issues. Women who are survivors need holistic, interdisciplinary, and specialist care that focuses on safety and needs. The adoption of regulations with robust enforcement guarantees and the facilitation of approvals for the construction of non-governmental shelters and safe houses should be on the agenda setting.

Estimating the cost and efficiency gain of rolling out a multi-month dispensing programme for antiretroviral treatment in Tanzania

Background: Globally, efforts to curtail the HIV pandemic are growing. The Joint United Nations Programme on HIV and AIDS (UNAIDS) and partners set the 95-95-95 targets to be achieved by 2025. Tanzania’s ongoing transition from single-month ARV to longer multi-month dispensing (MMD) involves significant planning and shifts in existing resources, including health commodities, clinical staff and storage space. This study aimed at evaluating the costs and efficiency gains of rolling out MMD compared to the prior monthly dispending (MD) standard of care before the new guidelines. Methods: The analysis employed a health provider perspective utilising prior costing data collected to estimate cost of treatment for HIV/AIDS, including salaries, laboratory costs, antiretroviral drugs, other supplies and overhead costs. The projections were run from 2018 to 2030 using the Spectrum package for Tanzania. Results: Our model estimated that total treatment cost without MMD (including salaries, laboratory costs, antiretroviral drugs, other supplies, and overhead costs) is estimated to rise from USD 189 million in 2018 to USD 244 million in 2030. The introduction of a six-month MMD would lead to the total annual facility-based treatment costs being reduced to USD 205 million in 2030. When comparing MD to a six-month MMD, the total savings over the 13-year period would be USD 425 million. The introduction of six-month MMD for stable patients would reduce the average cost from USD 180 to USD 156 per patient per year if stable patients were only required to make six-monthly visit. Conclusions: The introduction of differentiated service delivery models (DSDMs) and MMD is already contributing to significant cost savings for Tanzania and will continue to do so as the country puts more stable patients on MMD. The potential gains from MMD implantation could further be harnessed if retention of treatment and viral suppression monitoring are prioritised.

The HIV epidemic and the COVID-19 pandemic: A double tragedy for sub-Saharan African women.

After four decades of the HIV epidemic, women from sub-Saharan Africa remain at a differentially high risk of acquisition. The Joint United Nations Programme on HIV and AIDS (UNAIDS) statistics show that the majority of HIV infections occur in this population and region. Evidence from previous humanitarian crises demonstrated adverse maternal consequences as a result of neglect for the provision of essential maternal, sexual and reproductive health services. The ongoing COVID-19 pandemic has had a similar effect, including an additional risk of HIV acquisition amongst women in sub-Saharan Africa. The COVID-19 pandemic has aggravated the risk of sub-Saharan Africa women to HIV infection because of a multitude of factors including child marriages, teenage pregnancies, dropping out of school, increase in incidence of sexual and gender-based violence and reduced access to preventive and treatment services for HIV and sexually transmitted infections. These include provision of care for rape and sexual and gender-based violence victims and provision of pre-exposure and postexposure prophylaxis for HIV and other STIs. Failure to urgently restore and maintain robust HIV prevention and treatment during the ongoing COVID-19 pandemic poses a risk of reversing the gains made over the years in reducing the incidence and morbidity from HIV amongst the population of sub-Saharan Africa women. There is need for an urgent and robust discourse to formulate effective interventions for protecting women and girls living in sub-Saharan Africa from an aggravated risk of HIV infection during the ongoing COVID-19 pandemic and other future humanitarian crises.

Where have we come from and where are we going? The paediatric HIV programme in Johannesburg, South Africa, from 2004 to 2018: A retrospective analysis of programme trends

Background. The paediatric HIV treatment programme in South Africa (SA) has grown since its inception in 2004. Despite this impressive scale-up of antiretroviral therapy (ART) in children, the proportion of children started on ART and retained in care remains unacceptably low, with only 47% of the 340 000 HIV-positive children in SA on ART in 2020. Johannesburg is one of the districts in SA with the largest number of children living with HIV who are not on ART, and is a priority district for paediatric case finding and retention. Objectives. To describe the dynamics of the paediatric HIV programme in Johannesburg, SA. Methods. A secondary analysis was conducted on patient-level HIV treatment data from TIER.Net, the nationally mandated HIV/ART database. Children aged <15 years who received ART between January 2004 and June 2019 at public health facilities in Johannesburg were included. We reported the number of children on ART and the number who entered and exited the programme by age group over time, and analysed the trends of these indicators. Results. By December 2018, 7 630 children aged <15 years remained in Johannesburg’s paediatric ART programme: 82.5% were aged 5 - <15 years, with 54.1% of these being 10 - <15 years old. During the study period, 19 850 children were newly initiated on ART. New initiations slowed from 2013, to range from 1 172 to 1 373 yearly. In 2018, 34.2% of initiators were aged <1 year, 24.2% 1 - <5 years and 41.6% 5 - <15 years. Despite these initiations, the number of children on ART only grew by 97 in 2018, owing to programme losses. In 2018, 924 children (12.1%) aged out, 35 (0.5%) died and 983 (12.9%) were lost to follow-up (LTFU), the latter having increased from 10.7% in 2017. Of children who aged out of the paediatric ART programme, 56.3% remained in care at the same facility. Conclusion. Early in the SA ART roll-out, many children were found to be HIV infected and started on ART. This number started to slow in 2013, after which the growth rate of the paediatric HIV programme also began to slow. Scale-up of methods for identifying older children with HIV is needed. While ageing out of the paediatric programme is a consideration, the number of children LTFU remains unacceptably high. Further interrogation of barriers to paediatric retention is needed to help realise the Joint United Nations Programme on HIV and AIDS (UNAIDS) 90:90:90 goals for children in SA.

Individual and network factors associated with HIV self-testing among men who have sex with men in resource-limited settings in China.

HIV self-testing (HIVST) is a potential strategy to overcome challenges of HIV testing among men who have sex with men (MSM). However, for resource-limited settings, technology and diagnostic devices are lagging. Hence, we estimated the status and correlates of HIVST among MSM in resource-limited settings in China to inform the development of HIVST to reach United Nations Programme on HIV and AIDS (UNAIDS) targets to end HIV by 2030. A cross-sectional study was conducted among MSM in Nanning, Guangxi, China, between August 2019 and January 2020. The HIVST status was collected and data on social network features, sociodemographic information, risk behaviours, etc. were compared between prior- and non-HIVST MSM. Logistic regression analyses were conducted to examine the correlates of HIVST. The prevalence of HIVST among 446 MSM was 40.4% (95% confidence interval [CI] 35.8-44.9%). The main component of sociocentric network contains more prior-HIVST MSM (38.3%) than non-HIVST MSM (28.6%, P =0.031). More MSM with individual features such as substance use during anal sex (22.8% vs 15.4%, P =0.049) and multiple sexual partners (76.1% vs 59.4%, P <0.001) were detected among prior-HIVST MSM. In multivariable analysis, prior HIVST was associated with the strong strength of ego-alter ties in the egocentric network (adjusted odds ratio [aOR] 1.72; 95% CI 1.09-2.71), HIV-infected partners (aOR, 7.17; 95% CI, 1.40-36.60), and vaginal intercourse (aOR, 0.38; 95% CI, 0.17-0.85). HIVST coverage among MSM in resource-limited settings is suboptimal. Integrating social networks into testing services may be viable to promote HIVST in MSM within resource-limited settings.

Responding to the Essential Sexual and Reproductive Health Needs for Women During the COVID-19 Pandemic: A Literature Review.

The pandemic and its consequences have been shown to have a negative impact on the availability and accessibility of the basic services, including sexual and reproductive health (SRH) needs. The aim of this study was to investigate the responses to the essential SRH needs for women during the COVID-19 pandemic. This narrative review was conducted based on the Scale for Assessing Narrative Review Articles (SANRA), in order to present key activities for responding to the important SRH needs of women in the current COVID-19 pandemic. The literature search was performed through English databases of Cochrane Library, PubMed, Scopus and ScienceDirect, as well as Persian databases including Magiran and Scientific Information Database (SID). In addition, the World Health Organization (WHO), the Joint United Nations Programme on HIV and AIDS (UNAIDS) and the reports of Center for Disease Control and Prevention (CDC) were searched. The search was carried out from December 2019 up to 10 January 2021. Essential reproductive healthcare services for women during the COVID-19 pandemic were divided into six categories including access to contraception, safe abortion and post-abortion care, sexual health and sexually transmitted disease (STD) prevention, cervical cancer screening and prevention, maternity services and also addressing violence against women and girls. These essential needs should be considered as a priority by governments as well as public and private stakeholders. It seems that the implementation of the shifted strategies, active participation of public and private stakeholders, consideration of human rights and ethical issues, ensuring access to vulnerable populations, regular contact with individuals and the increased cooperation of individuals for responding to the SRH needs during the COVID-19 outbreak, are necessary.

INNATE IMMUNITY AGAINST HIV AMONG HIGHLY EXPOSED SERO-NEGATIVE (HESN) FEMALE SEX WORKERS

In 2010, the UNAIDS (Joint United Nations Program on HIV and AIDS) evaluates that the greater part surprisingly living with HIV/AIDS are women. It is assessed that, in Africa, ladies are twice as liable to contract HIV-1 through sexual intercourse involving vagina contrasted to men and are along these lines thought to be vulnerable persons in the population. The improvement of a female microbicide that gives security against HIV-1 infection is a promising preventive and precaution strategy.

The Impact of Peer Educators or Community Health Workers on the Progress of the UNAIDS 90-90-90 Targets in Africa: A Systematic Review and Meta-Analysis Protocol

Background: Africa is far behind from achieving the Joint United Nations Program on HIV and AIDS (UNAIDS) 90-90-90 targets. Evidence shows that the participation of HIV patients as peer educators and other community health workers is substantially improving the entire HIV care continuum and subsequently the UNAIDS targets. This review aims to provide the best available evidence on the impact of peer educators and/or community health workers for the three targets in Africa. Methods: We will include cohort and experimental studies published in English between 2003 and 2020. Studies which reported interventions for HIV diagnosis, initiation of ART, or virological suppression will be included for review. Three steps searching will be conducted: (i) initial search across Google Scholar, (ii) full search strategy across five databases: MEDLINE, PubMed, CINAHL, SCOPUS and Web of Science, and (iii) screening titles and abstracts. Data will be extracted using standardized instruments from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) and analyzed through narrative synthesis, and meta-analyses and regression. Heterogeneity among quantitative studies will be assessed using Cochran Q test and Higgins I2. Ethics: A formal ethical approval will not be required as primary data will not be collected.

How Does the Covıd-19 Pandemıc Affect the Target 90-90-90?

In 2014, The Joint United Nations Program on HIV and AIDS (UNAIDS) has set an ambitious target code-named 90-90-90, which aims to ensure that 90% of all people living with HIV will know their state, 90% of all people diagnosed will receive sustained antiretroviral therapy, and 90% of all people receiving ART will have viral suppression by 2020. Since 2014, many tests and treatment programs have been developed to achieve the above goals worldwide. In 2019, it was reported that many developed countries can reach the target with the right strategies, as well as regions that are still far from the targets. It has been reported that the fourth 90 should be one of the targets related to HIV infection in recent years. This view, beyond virological suppression, was towards developing programs that would enable people living with HIV to live not only longer but also healthy. The socio-cultural and economic obstacles to reach the targets may vary according to geographical regions, but it is clear that COVID-19 disease, which has taken the whole world under the influence since 2019, is a major obstacle to the 90-90-90 targets worldwide. Difficulties in the diagnosis and access to ART and treatment nonadherence which may be encountered more frequently due to many factors may threaten both the health of people living with HIV and public health. The COVID-19 pandemic has disrupted many programs developed in the fight against the HIV epidemic. Considering COVID-19 disease and future epidemics that may create a chaotic environment, analyzing the difficulties experienced in the pandemic retrospectively, and determining new strategies that will bring appropriate solutions to the problems will play an important role in the proper management of future issues.

Multi-level barriers to reaching HIV testing among young heterosexual African migrants from HIV-endemic countries in Ottawa

The Joint United Nations Programme on HIV and AIDS (UNAIDS) and the Public Health Agency of Canada wish to reach, test and treat at least 90 percent of undiagnosed people living with HIV. Fourteen percent (9,090 of 63,100) of Canadians living with HIV were unaware of their status by the end of 2016. Evidence about barriers before and after reaching testing is required to inform policy and practice in planning more equitable HIV testing interventions. We conducted face-to-face semi-structured interviews among twenty young heterosexual African migrants from HIV-endemic countries between May and October 2017. Participants included fourteen men and six women aged 18–29 years to identify barriers to reaching HIV testing services in Ottawa. We used Grounded Theory informed by a socio-ecological framework and a framework of access to care. Participants described access barriers and enablers at the testing stages of approachability, acceptability, and availability. Participants were, however, often unable to recognize the need for HIV testing, unable to actively seek and choose HIV testing and reach HIV testing at the intrapersonal, interpersonal, organizational, community, and policy levels. Lack of outreach programs and inability to obtain required information about HIV testing options was a major access barrier among young men in this study. Young heterosexual African women experienced unique barriers even after reaching testing, such as, not being taken seriously by healthcare providers. Our analysis showed multi-level determinants influence our populations HIV testing, both before and after reaching testing services. These determinants have practical implication for researchers, policymakers, affected communities and patients.

A Phenomenological Account of HIV Disclosure Experiences of Children and Adolescents from Northern and Southern Ghana.

Disclosure of HIV status to infected children, though challenged by caregiver dilemma, remains central in achieving the United Nations Programme on HIV and AIDS (UNAIDS) global goal of 90/90/90. This study explores children’s HIV disclosure experiences across Northern and Southern Ghana. A qualitative interpretative phenomenological design facilitated the recruitment of 30 HIV positive disclosed children and adolescents aged 9–19 years in 12 antiretroviral treatment (ART) centers in Northern and Southern Ghana between January 2017 and June 2018. Data was collected via in-depth interviews. We used phenomenological analysis applying concepts and categories identification, patterns and interconnections searching, mapping, theme building and constant comparative technique to draw conclusions. Disclosure of HIV status to children occurred with little or no preparation. Caregivers intentionally or out of dilemma often prolonged or postponed disclosure to when children aged older. Illness severity and disease progression principally defined the need for disclosure. Children preference for early status disclosure averaged at age 10 was demonstrated despite the initial disclosure experience of shock and disappointment. There was improved medication adherence despite the challenge of limited knowledge about HIV transmission, financial difficulty and food insecurity. Context and culturally adapted pre- and post- disclosure guideline laced with social protection package is needed to support HIV positive children.

Progress Towards the 90-90-90 Targets for Controlling HIV — China, 2018

What is already known about this topic? Since the Joint United Nations Programme on HIV and AIDS (UNAIDS) announced the 90-90-90 targets to control the global HIV epidemic in 2014, many countries have undertaken innovative measures to achieve this goal. The National Center for AIDS/STD Control and Prevention (NCAIDS) of China CDC convenes experts annually to evaluate the national progress towards these indicators. The most recent progress of 90-90-90 targets in China has not been previously published. What is added by this report? At the end of 2018, the percentage of living with HIV (PLWH) who had received a confirmed HIV diagnosis in China was 68.9% (61.5%-78.3%). The antiretroviral treatment coverage of diagnosed PLWH was 83.4%, and among patients on treatment for at least 12 months, 94.2% achieved viral suppression. This provides most recent progress of 90-90-90 target in China. What are the implications for public health practice? China has made significant strides in curbing the HIV epidemic, but analysis on progress for the first 90 target for HIV testing remains out of reach. Innovative testing strategies may need to be developed to ensure that more PLWH can be identified.

Substantial Heterogeneity in Progress Toward Reaching the 90-90-90 HIV Target in the WHO European Region.

Background:Achieving the UNAIDS 90-90-90 target by 2020 is expected to end the HIV epidemic by 2030. We report on progress in the WHO European Region in meeting this target.Methods:The European Centre for Disease Prevention and Control (ECDC) sent questionnaires to 55 countries in 2016. We report estimates for 4 stages of the continuum of HIV care (living with HIV, diagnosed, treated, and virally suppressed), corresponding to the Joint United Nations Programme on HIV and AIDS (UNAIDS) target and explore differences by subregion and challenges with reporting data.Findings:Forty-four countries provided data for ≥1 stage, and 29 for all 4 stages. Estimated HIV prevalence was 0.19% (range 0.02%–0.84%, n = 37 countries providing stage 1 data). The proportion diagnosed of people living with HIV ranged from 38% to 98% (n = 37 reporting number of people living with HIV and diagnosed). The proportion on ART of those diagnosed ranged from 27% to 96% (n = 40 reporting numbers diagnosed and treated), and viral suppression rates ranged from 32% to 97% (n = 31 providing numbers treated and virally suppressed). The overall continuum of care estimate for 29 countries with complete data was 81-84-88, which differed by subregion: 84-88-90, 84-69-62, and 57-45-57 for the western, central, and eastern subregions, respectively. Challenges in reporting data included absence of a single data source for all stages, shortage of expertise, and lack of financial and human resources.Conclusions:There is an urgent need to strengthen HIV testing programs throughout Europe, particularly in the eastern subregion, and to remove constraints hampering access to testing and care. Recent changes to treatment guidelines should help reduce the numbers diagnosed not treated.

Resistance profile and treatment outcomes in HIV-infected children at virological failure in Benin, West Africa.

In Africa a high percentage of HIV-infected children continue to experience HIV treatment failure despite enormous progress. In Benin (West Africa), there are currently no data on HIV drug resistance at failure in paediatric populations. To assess the frequency and patterns of HIV drug resistance among children with virological ART failures. Dried blood spots from 62 HIV-infected children with virological failure were collected at the paediatric clinic of the National Hospital Center in Cotonou for genotyping and plasma drug concentration determination. Characteristics of the population show a median age of 10 years (IQR 6-13) and a median duration on ART of 5 years (IQR 3-7). Viruses from 53 children were successfully amplified. Of these, 76% of patients were on an NNRTI-based regimen and 24% on a boosted PI-based regimen. NRTI, NNRTI and dual-class resistance was present in 71%, 84% and 65% of cases, respectively. Only 4% of the children had major resistance mutations to PIs and none had major resistance mutations to integrase inhibitors. Among the participants, 25% had undetectable antiretroviral concentrations. Our results showed that the development of drug resistance could be one of the main consequences of high and continuous viral replication in HIV-infected children in Benin. Thus, inadequate attention to monitoring lifelong ART in children may prevent achievement of the goal of the United Nations Program on HIV and AIDS (UNAIDS) of 90% viral suppression among patients receiving ART.

Factors Associated With Poor Linkage to HIV Care in South Africa: Secondary Analysis of Data From the Thol'impilo Trial

Poor linkage to HIV care is impeding achievement of the Joint United Nations Programme on HIV and AIDS (UNAIDS) 90-90-90 targets. This study aims to identify risk factors for poor linkage-to-care after HIV counseling and testing, thereby informing strategies to achieve 90-90-90. The Thol'impilo trial was a large randomized controlled trial performed between 2012 and 2015 in South Africa, comparing different strategies to improve linkage-to-care among adults aged ≥18 years who tested HIV-positive at mobile clinic HIV counseling and testing. In this secondary analysis, sociodemographic factors associated with time to linkage-to-care were identified using Cox regression. Of 2398 participants, 61% were female, with median age 33 years (interquartile range: 27-41) and median CD4 count 427 cells/mm (interquartile range: 287-595). One thousand one hundred one participants (46%) had clinic verified linkage-to-care within 365 days of testing HIV-positive. In adjusted analysis, younger age [≤30 vs >40 years: adjusted hazard ratio (aHR): 0.58, 95% CI: 0.50 to 0.68; 31-40 vs >40 years: aHR: 0.81, 95% CI: 0.70 to 0.94, test for trend P < 0.001], being male (aHR: 0.86, 95% CI: 0.76 to 0.98, P = 0.028), not being South African (aHR: 0.79, 95% CI: 0.66 to 0.96, P = 0.014), urban district (aHR: 0.82, 95% CI: 0.73 to 0.93, P = 0.002), being employed (aHR: 0.81, 95% CI: 0.72 to 0.92, P = 0.001), nondisclosure of HIV (aHR: 0.63, 95% CI: 0.56 to 0.72, P < 0.001), and having higher CD4 counts (test for trend P < 0.001) were all associated with decreased hazard of linkage-to-care. Linkage-to-care was low in this relatively large cohort. Increasing linkage-to-care requires innovative, evidence-based interventions particularly targeting individuals who are younger, male, immigrant, urban, employed, and reluctant to disclose their HIV status.

Towards standardized definitions for monitoring the continuum of HIV care in Europe.

The continuum of HIV care is a simple conceptual framework for monitoring HIV programmes, comprising a series of stages that people living with HIV (PLHIV) pass through to access antiretroviral treatment (ART) and achieve viral suppression [1,2]. Individual benefits of suppression include reduced risk of morbidity and mortality. At the population level, viral suppression reduces the risk of onward transmission and enables epidemic containment [3]. Transmission risk may be further reduced by lowering the number of undiagnosed PLHIV [4,5]. Complete continua are, therefore, constructed beginning with the total number of PLHIV in a given population and ending with the number virally suppressed. Intervening stages have included the numbers diagnosed, linked to HIV care, retained in care, eligible for ART, on ART and adhering to ART. Although people can move between stages, the continuum is typically conceptualized as a ‘snapshot’ at one time-point. As the Joint United Nations Programme on HIV and AIDS (UNAIDS) announced the target of reaching ‘90-90-90’ by 2020, which envisions 90% of PLHIV diagnosed, 90% of those diagnosed on ART and 90% of those on ART virally suppressed [6], interest in constructing HIV care continua to inform national programmes and policies has grown [7–11]. However, there has been limited consistency in the methods used to construct these measures and the stages presented in publications. Key stages are often missing or continua entirely absent for many countries, including in Europe, particularly the Eastern region [7,8,11–15]. Drawing from a review of recent literature and expert opinion, we highlight the methodological inconsistencies, the challenges associated with constructing each stage and recommend a standardized way forward for monitoring the continuum of HIV care in Europe.

Medical male circumcision coverage in Rakai, Uganda.

We assessed medical male circumcision (MMC) scale-up in Rakai, Uganda using population-based surveys during 2007-2014. MMC coverage increased from 28.5 to 52.0%. Coverage was initially lower in 15-19-year-olds but increased in 2014, was higher in married men and in trading communities, and lowest in the sexually inactive. Coverage did not vary by self-perceived risk of HIV or HIV serostatus. Increasing generalized coverage suggested that MMC became normative, but coverage falls short of WHO/Joint United Nations Programme on HIV and AIDS (UNAIDS) 80% targets, indicating the need for demand generation.

Can the UNAIDS 90-90-90 target be achieved? A systematic analysis of national HIV treatment cascades.

BackgroundIn 2014, the Joint United Nations Programme on HIV and AIDS (UNAIDS) and partners set the ‘90-90-90 targets’; aiming to diagnose 90% of all HIV positive people, provide antiretroviral therapy (ART) for 90% of those diagnosed and achieve viral suppression for 90% of those treated, by 2020. This results in 81% of all HIV positive people on treatment and 73% of all HIV positive people achieving viral suppression. We aimed to analyse how effective national HIV treatment programmes are at meeting these targets, using HIV care continuums or cascades.MethodsWe searched for HIV treatment cascades for 196 countries in published papers, conference presentations, UNAIDS databases and national reports. Cascades were constructed using reliable, generalisable, recent data from national, cross-sectional and longitudinal study cohorts. Data were collected for four stages; total HIV positive people, diagnosed, on treatment and virally suppressed. The cascades were categorised as complete (four stages) or partial (3 stages), and analysed for ‘break points’ defined as a drop >10% in coverage between consecutive 90-90-90 targets.Results69 country cascades were analysed (32 complete, 37 partial). Diagnosis (target one—90%) ranged from 87% (the Netherlands) to 11% (Yemen). Treatment coverage (target two—81% on ART) ranged from 71% (Switzerland) to 3% (Afghanistan). Viral suppression (target three—73% virally suppressed) was between 68% (Switzerland) and 7% (China).ConclusionsNo country analysed met the 90-90-90 targets. Diagnosis was the greatest break point globally, but the most frequent key break point for individual countries was providing ART to those diagnosed. Large disparities were identified between countries. Without commitment to standardised reporting methodologies, international comparisons are complex.
