Impact of Awareness of Sexual Partners' HIV Serostatus on the HIV Acquisition among Men Who Have Sex with Men in Guangzhou, China: A Nested Case-Control Study.

This study aimed to investigate the impact of sexual partners' HIV serostatus awareness on theHIV acquisition among men who have sex with men (MSM) in Guangzhou, China. A nested case-control study was conducted based on a prospective cohort of MSM in Guangzhou. Within the cohort, individuals who underwent HIV seroconversion were identified as the case group, and each case was matched with four controls from the non-seroconverted participants. Information regarding the awareness of sexual partners' HIV serostatus over the preceding 6months was gathered. Of the 161 participants, 36.0% were aware of the HIV serostatus of all their sexual partners. The practice of engaging in condomless anal sex with partners of unknown HIV serostatus and being aware of the HIV serostatus of only some casual partners were positively correlated with an elevated risk of acquiring HIV. Conversely, being fully aware of the HIV serostatus of all sexual partners, including regular ones, was associated with a diminished risk of HIV incidence.Regular communication with sexual partners regarding HIV testing outcomes, honest disclosure of one's own HIV serostatus, and refusal of sexual contact with partners of unknown HIV serostatus can potentially mitigate the risk of acquiring HIV among MSM.

Sexual network characteristics, condomless anal intercourse, and the HIV care cascade among MSM living with controlled versus uncontrolled HIV infection in Lima, Peru: a population-based cross-sectional analysis

Despite high rates of HIV transmission among men who have sex with men (MSM) in Lima, Peru, limited data exist on the sexual network characteristics or risk factors for secondary HIV transmission among MSM with uncontrolled HIV infection. We report the frequency of serodiscordant, condomless anal intercourse (CAI) and associated sexual network characteristics among MSM in Lima with detectable HIV viremia and compare to those with undetectable viremia. This cross-sectional analysis includes MSM who tested positive for HIV-1 during screening for a trial of partner management and STI control (June 2022-January 2023). Participants were tested for HIV, gonorrhoea, chlamydia, and syphilis, and completed questionnaires on their demographic characteristics, sexual identity and behaviour, sexual network structures and engagement in HIV care. Of 665 MSM, 153 (23%) had detectable (>200 copies/mL) viremia. 75% (499/662) of men living with HIV were previously diagnosed, with 94% (n=469/499) reporting that they were on ART, and 93% (n=436/469) virally suppressed. 96% (n=147/153) of men with detectable viremia reported serodiscordant CAI with at least one of their last three sexual partners, and 74% (n=106/144) reported the same with all three of their recent partners. In contrast, 62% (n=302/489) of men with undetectable viral load reported serodiscordant CAI with all of their last three partners (p<0.01). 23% of men living with HIV in Peru had detectable viremia, of whom almost all (96%) reported recent serodiscordant CAI. The primary gap in the HIV care cascade lies in awareness of HIV serostatus, suggesting that improved access to HIV testing could be a key prevention strategy in Peru. Funding for this study was provided by NIH/NIMH grants R01 MH118973 (PI: Clark) and R25 MH087222 (PI: Clark).

Factors influencing the use of multiple HIV prevention services among transport workers in a city in southwestern Uganda

The use of multiple HIV prevention services has been found to decrease the risk of acquiring HIV when tailored to individuals at risk of HIV exposure, including transport workers. Therefore, we assessed the uptake of multiple HIV prevention services (≥2) and associated factors among transport workers in a city in Southwestern Uganda. This cross-sectional study comprised motorcycle taxi riders, motor vehicle and truck drivers, aged 18 to 55 years who were selected and responded to an interviewer-administered questionnaire, between November 2021 and February 2022. Data was analyzed using descriptive statistical and modified Poisson regression analyses. Out of 420 participants, 97.6% were male, with a median age of 28 years and the majority were aged <34 years (84.6%). Overall, less than half (45.3%) of the participants had used multiple (≥2) HIV prevention services within a one-year period. Many participants had used condoms (32.2%) followed by voluntary HIV counseling and testing (27.1%), and safe male circumcision (17.3%). Most participants who tested for HIV had ever used condoms (16.2%), followed by those who received safe male circumcision and had ever used condoms (15%), and those who tested for HIV and had started on antiretroviral therapy (ART) (9.1%). In the adjusted model, factors that were significantly associated with the use of multiple HIV prevention services included religion (aPR = 1.25, 95% CI = 1.05-1.49), the number of concurrent sex partners (aPR = 1.33, 95% CI = 1.10-1.61), prior HIV testing and awareness of HIV serostatus (aPR = 0.55, 95% CI = 0.43-0.70), awareness of HIV prevention services (aPR = 2.49, 95% CI = 1.16-5.38), and financial payment to access HIV services (aPR = 2.27, 95% CI = 1.47-3.49). In conclusion, the uptake of multiple HIV prevention services among transport workers remains suboptimal. Additionally, individual behavioral factors influence the use of multiple HIV services compared with other factors. Therefore, differentiated strategies are needed to increase the utilization of HIV prevention services among transport workers.

Determinants of testing for HIV among young people in Uganda. A nested, explanatory-sequential study.

Awareness of HIV serostatus helps individuals calibrate behaviour or link to care. Globally, young people (15-24years) contribute over 30% of new HIV infections. Despite progress in enhancing access to HIV services, HIV testing among young people in Uganda is below target. We determined the prevalence and factors influencing HIV testing among young people in a peri-urban district with the highest proportion of young people. We conducted a nested explanatory sequential mixed-methods study from March to May 2019 in Wakiso district. We used stratified cluster random sampling to select 397 rural and 253 urban young people from eight parishes. We collected data using questionnaires and subsequently conducted in-depth interviews with 16 purposively selected survey participants. The prevalence of testing for HIV was 80.2%. Young people related their decisions about HIV testing to self-evaluation of their risk and perceived ability to manage the consequences of a positive result. Participants reported high levels of support for HIV testing from peers, partners, and family members. They perceived health facilities as confusing, distant, expensive, and staffed by judgmental, older health workers as barriers. They felt that mobile testing points solved some of these problems, but introduced less privacy and greater confidentiality concerns. The prevalence of HIV testing among young people in Wakiso district was low compared to the UNAIDS 2030 target but among the highest in sub-Saharan Africa. Community-based programs resolve many concerns about testing at health facilities. However, there is a need to make these programs more comfortable and private.

Analysing behavioural outcome effectiveness in a musical theatre-based HIV/AIDS intervention among South African farm workers.

In 2005, an applied theatre community outreach programme was launched to address low levels of HIV/AIDS awareness among farm workers in the Cape Winelands of South Africa. In cooperation with HIV testing organizations, the Lucky, the Hero mini-musical promoted regular HIV testing, condom use and acceptance of people living with HIV until being retired in 2017. Applying principles of the health belief model to interview data collected in 2015 from former Lucky, the Hero participants, this paper examines the effectiveness of the theatre production to achieve the behavioural outcomes of (i) encouraging regular HIV testing and ongoing awareness of HIV serostatus, and (ii) reducing AIDS-related social stigma. The findings suggest that the interventions were successful in persuading participants to know their HIV status immediately following the shows, as well as potentially contributing to a reduction of community-based external social stigma. However, the interventions were unable to maintain engagement with these behavioural outcomes in the years following the performances, resulting in low adherence to regular HIV testing and inconsistent condom use. Additionally, ongoing social and structural barriers to regular HIV testing and the potential for self-imposed HIV-related stigma were highlighted during the discussions. While applied theatre can be an effective avenue for HIV awareness and prevention, the paper demonstrates the importance of creating and maintaining strong community networks to support continued engagement with health-related behavioural outcomes.

Awareness of HIV serostatus by sex partners of women living with HIV in North-Central Nigeria: correlates and predictive analyses.

Non-communication of HIV status among sex partners is a notable hurdle in halting transmission, largely due to socio-cultural factors. This study aimed to predict the determinants of male partners' awareness of women's serostatus. A total of 8825 women of reproductive age living with HIV who were clients at five comprehensive HIV treatment centres in Benue State, North-Central Nigeria were surveyed between June and December 2017, and 6655 reported having a sexual partner at the time of the survey selected for analysis. A regression model was used to estimate the determinants of male partner awareness of serostatus from the perspective of women. Conditional marginal analyses were conducted to evaluate the marginal effects of identified predictors on the probability of outcomes. Partners of married women were found to have greater odds of being aware of their spouse's serostatus (adjusted OR (aOR): 3.20; 95%CI: 2.13-4.81) than non-married partners. Similarly, the odds of male partner awareness increased with the years women had been on antiretroviral therapy (aOR: 1.13; 95%CI: 1.07-1.20). The probability of partners of married respondents being aware of their spouse's HIV serostatus was 97%. The conditional marginal effects of being educated to primary or higher level were 1.2 (95% CI: -0.2 to 2.7) and 1.8 (95% CI: 0.09-3.4) percentage points higher respectively when compared with women with no formal education. Being unemployed or being a trader significantly decreased the probability of partners being aware of respondents' serostatus when compared with farmers; conditional marginal effects of -6.7 (95% CI: -12.0 to -1.4) and -3.9 (95% CI: -5.7 to -2.2) percentage points, respectively. The study found that relationship status and girl-child education are factors that can improve communication of HIV status to sex partners. Policies and interventions aimed at improving the social determinants of health, and social support for healthy communications in relationships, are recommended to reduce HIV transmission between sex partners.

Heterosexual Cisgender Men Partnered with Transgender Women Exhibit Higher HIV/STI Sexual Risk than Their Gay, Bisexual, and Queer Counterparts: Findings from a U.S.-Based Convenience Sample Recruited Online.

Cisgender men are frequently vectors for HIV transmission among transgender women. Despite this, the correlates of sexual risk among these men remain under-examined. The purpose of the present study was to explore potential differences in relationship characteristics, sexual risk-taking, and risk-reduction strategies among cisgender men partnered with transgender women. The study utilized secondary screening data provided by adult cis men who reported being in a primary relationship with a trans woman (N = 710). Gay men (18%) were comparatively older, and most likely to report both HIV seropositivity and committed pairings. Heterosexual men (14%) were more likely to report exchange sex, briefer relationships, extra-dyadic sex, lesser serostatus awareness or PrEP uptake. Queer men (7%) were youngest, and most likely to access PrEP. Heterosexual cis men with trans women partners may be subject to unique socio-cultural drivers of sexual risk, such as heteronormative pressures and relationship stigma.

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

HIV-infected men have higher rates of delayed diagnosis, reduced antiretroviral treatment (ART) retention and mortality than women. We aimed to assess, by gender, the first two UNAIDS 90 targets in rural southern Mozambique. This analysis was embedded in a larger prospective cohort enrolling individuals with new HIV diagnosis between May 2014-June 2015 from clinic and home-based testing (HBT). We assessed gender differences between steps of the HIV-cascade. Adjusted HIV-community prevalence was estimated using multiple imputation (MI). Among 11,773 adults randomized in HBT (7084 female and 4689 male), the response rate before HIV testing was 48.7% among eligible men and 62.0% among women (p<0.001). MI did not significantly modify all-age HIV-prevalence for men but did decrease prevalence estimates in women from 36.4%to 33.0%. Estimated proportion of HIV-infected individuals aware of their status was 75.9% for men and 88.9% for women. In individuals <25 years, we observed up to 22.2% disparity in awareness of serostatus between genders. Among individuals eligible for ART, similar proportions of men and women initiated treatment (81.2% and 85.9%, respectively). Fourfold more men than womenwere in WHO stage III/IV AIDS at first clinical visit. Once on ART, men had a twofold higher 18-month loss to follow-up rate than women. The contribution of missing HIV-serostatus data differentially impacted indicators of HIV prevalence and of achievement of UNAIDS targets by age and gender and men were missing long before the second 90. Increased efforts to characterize missing men and their needs will and their needs will allow us to urgently address the barriers to men accessing care and ensure men are not left behind in the UNAIDS 90-90-90 targets achievement.

Research Priorities to End the Adolescent HIV Epidemic in the United States: Viewpoint.

Youth represent 21% of new HIV diagnoses in the United States. Gay, bisexual, and transgender (GBT) youth, particularly those from communities of color, and youth who are homeless, incarcerated, in institutional settings, or engaging in transactional sex are most greatly impacted. Compared with adults, youth have lower levels of HIV serostatus awareness, uptake of antiretroviral therapy (ART), and adherence. Widespread availability of ART has revolutionized prevention and treatment for both youth at high risk for HIV acquisition and youth living with HIV, increasing the need to integrate behavioral interventions with biomedical strategies. The investigators of the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) completed a research prioritization process in 2019, focusing on research gaps to be addressed to effectively control HIV spread among American youth. The investigators prioritized research in the following areas: (1) innovative interventions for youth to increase screening, uptake, engagement, and retention in HIV prevention (eg, pre-exposure prophylaxis) and treatment services; (2) structural changes in health systems to facilitate routine delivery of HIV services; (3) biomedical strategies to increase ART impact, prevent HIV transmission, and cure HIV; (4) mobile technologies to reduce implementation costs and increase acceptability of HIV interventions; and (5) data-informed policies to reduce HIV-related disparities and increase support and services for GBT youth and youth living with HIV. ATN’s research priorities provide a roadmap for addressing the HIV epidemic among youth. To reach this goal, researchers, policy makers, and health care providers must work together to develop, test, and disseminate novel biobehavioral interventions for youth.

Hepatitis B Awareness and Vaccination Patterns among Healthcare Workers in Africa.

Hepatitis B virus (HBV) vaccination patterns and the understanding of its risks among healthcare workers (HCWs) is a critical step to decrease transmission. However, the depth of this understanding is understudied. We distributed surveys to HCWs in 12 countries in Africa. Surveys had nine multiple-choice questions that assessed HCWs' awareness and understanding of HBV. Participants included consultants, medical trainees, nurses, students, laboratory personnel, and other hospital workers. Surveys were completed anonymously. Fisher's exact test was used for analysis, with a P-value of < 0.05 considered significant; 1,044 surveys were collected from Kenya, Egypt, Sudan, Tanzania, Ethiopia, Uganda, Malawi, Madagascar, Nigeria, Cameroon, Ghana, and Sierra Leone. Hepatitis B virus serostatus awareness, vaccination rate, and vaccination of HCWs' children were 65%, 61%, and 48%, respectively. Medical trainees had higher serostatus awareness, vaccination rate, and vaccination of their children than HCWs in other occupations (79% versus 62%, P < 0.001; 74% versus 58%, P < 0.001; and 62% versus 45%, P = 0.006, respectively). Cost was cited as the most frequent reason for non-vaccination. West African countries were more aware of their serostatus but less often vaccinated than East African countries (79% versus 59%, P < 0.0001 and 52% versus 60%, P = 0.03, respectively). West African countries cited cost as the reason for non-vaccination more than East African countries (59% versus 40%, P = 0.0003). Our study shows low HBV serostatus awareness and vaccination rate among HCWs in Africa, and reveals gaps in the perception and understanding of HBV prevention that should be addressed to protect HCWs and improve their capacity to control HBV infection.

The first 90: the gateway to prevention and care: opening slowly, but not for all.

Knowledge of HIV status is the gateway to HIV treatment and prevention, and optimizing this pillar is essential to bend the curve of the HIV epidemic toward zero new infections. This review will discuss the epidemiology of serostatus awareness, including disparities among key populations, and explore interventions and societal barriers. Rates of serostatus awareness have improved overall; however, progress is lagging in many regions, nations and populations, with substantial disparities seen among key populations. These populations and their partners now contribute the majority of new infections, fueling the epidemic. Data support a variety of interventions that have demonstrated effectiveness in increasing new diagnoses, particularly among underserved populations. Structural and societal barriers such as stigma, discriminatory laws and policies, and social determinants of health disproportionately affect key populations, and these must be addressed to achieve equity and end the epidemic. According to United Nations Programme on HIV/AIDS (UNAIDS), the pace of progress toward epidemic control has slowed. Achieving substantial increases in serostatus awareness to meet 2020 and 2030 UNAIDS goals will require attacking complex societal barriers while bringing evidence-based interventions to scale in each nation and key population. A robust advocacy effort is now needed as political will and funding wane.

HIV serostatus knowledge and serostatus disclosure with the most recent anal intercourse partner in a European MSM sample recruited in 13 cities: results from the Sialon-II study

BackgroundKnowledge of HIV status can be important in reducing the risk of HIV exposure. In a European sample of men-who-have-sex-with-men (MSM), we aimed to identify factors associated with HIV serostatus disclosure to the most recent anal intercourse (AI) partner. We also aimed to describe the impact of HIV serostatus disclosure on HIV exposure risks.MethodsDuring 2013 and 2014, 4901 participants were recruited for the bio-behavioural Sialon-II study in 13 European cities. Behavioural data were collected with a self-administered paper questionnaire. Biological specimens were tested for HIV antibodies. Factors associated with HIV serostatus disclosure with the most recent AI partner were examined using bivariate and multilevel multivariate logistic regression analysis. We also describe the role of serostatus disclosure for HIV exposure of the most recent AI partner.ResultsThirty-five percent (n = 1450) of the study participants reported mutual serostatus disclosure with their most recent AI partner or disclosed having HIV to their partner. Most of these disclosures occurred between steady partners (74%, n = 1077). In addition to the type of partner and HIV diagnosis status, other factors positively associated with HIV serostatus disclosure in the multilevel multivariate logistic regression model were recent testing, no condom use, and outness regarding sexual orientation. Disclosure rates were lowest in three south-eastern European cities.Following condom use (51%, n = 2099), HIV serostatus disclosure (20%, n = 807) was the second most common prevention approach with the most recent AI partner, usually resulting in serosorting. A potential HIV exposure risk for the partner was reported by 26% (111/432) of HIV antibody positive study participants. In 18% (20/111) of exposure episodes, an incorrect HIV serostatus was unknowingly communicated. Partner exposures were equally distributed between steady and non-steady partners.ConclusionsThe probability of HIV exposure through condomless AI is substantially lower after serostatus disclosure compared to non-disclosure. Incorrect knowledge of one’s HIV status contributes to a large proportion of HIV exposures amongst European MSM. Maintaining or improving condom use for anal intercourse with non-steady partners, frequent testing to update HIV serostatus awareness, and increased serostatus disclosure particularly between steady partners are confirmed as key aspects for reducing HIV exposures amongst European MSM.

Correlates of Unknown HIV Status Among MSM Participating in the 2014 American Men's Internet Survey (AMIS).

Increasing serostatus awareness is a key HIV prevention strategy. Despite expanded testing efforts, some men who have sex with men (MSM) remain unaware of their HIV status. This study explored demographic characteristics, sexual identity, sexual role, and behavioral factors associated with unknown HIV status among MSM in the United States. Data from 9170 MSM in the 2014 American Men's Internet Survey were analyzed using logistic regression to identify correlates of unknown HIV status. Young age, race, low education, rural residence, and lack of recent healthcare visits were significantly associated with unknown HIV status. In addition, nondisclosure of one's sexual orientation (OR=3.70, 95% CI 2.99-4.59) and a self-identified sexual role as "bottom" (OR=1.45, 95% CI 1.24-1.70) were predictors of unknown HIV status. Post-hoc analysis showed HIV-negative MSM not tested in the last year had fewer self-reported risk behaviors than recent testers, suggesting that repeat testing among MSM may be aligned with individual risk.

Demographic, clinical and behavioural determinants of HIV serostatus non-disclosure to sex partners among HIV-infected pregnant women in the Eastern Cape, South Africa.

ObjectivesDrawing from a baseline sample of a cohort study, the study examines the extent and correlates of serostatus non-disclosure to sex partners and family members, and reasons for non-disclosure among HIV-infected pregnant women in the Eastern Cape Province, South Africa.MethodsThis longitudinal cohort study recruited 1709 pregnant women living with HIV who attended three of the largest maternity centres in the Eastern Cape, South Africa, for delivery between September 2015 and May 2016. Relevant items on demographics, serostatus awareness, disclosure to sex partners and family members, and lifestyle behaviours were obtained using structured interviews. Age-stratified binary logistic regression models were used to determine the significant correlates of non-disclosure among the participants.ResultsA higher rate of HIV serostatus non-disclosure to sex partners (25.6%) in comparison to family members (20%) was reported by the participants. Younger age, not living with partners and alcohol use were significantly associated with non-disclosure of HIV serostatus to sex partners. Non-disclosure of HIV serostatus to sex partners was significantly (p<0.05) associated with poor adherence to the highly active anti-retroviral therapy (HAART), failure to keep clinic appointments and high viral load at the delivery of the baby. Perceived fear of intimate partner violence, fear of rejection, guilt of not disclosing at the onset of the relationship, sex partner’s non-disclosure of HIV serostatus, and guilt of unfaithfulness were some of the reasons for non-disclosure of HIV serostatus to sex partners.ConclusionsNon-disclosure of HIV serostatus is a public health concern with serious implications for both mother-to-child transmission, as well as horizontal transmission, in our setting. Strategic efforts toward ending the epidemic of HIV and AIDS in South Africa should address the sociocultural and behavioural determinants of non-disclosure.

U.S. HIV Incidence and Transmission Goals, 2020 and 2025

The recently updated U.S. National HIV/AIDS Strategy sets key HIV prevention and care targets for 2020, but the trajectory of the epidemic remains unclear. Authors modeled HIV incidence, prevalence, and mortality for the U.S. over 10 years to determine whether an ambitious trajectory toward "ending AIDS" by 2025 would be achievable. Authors utilized recently published 2010-2013 Centers for Disease Control and Prevention surveillance data to model HIV incidence, prevalence, and mortality. Authors applied a 90/90/90 framework (90% awareness of serostatus, 90% of diagnosed individuals in care, and 90% of individuals on antiretroviral therapy virally suppressed) by 2020 and 95/95/95 by 2025 to assess the feasibility of meeting epidemiologic targets. Analyses were conducted in 2016. With a goal of reducing infections to 21,000 new HIV infections in 2020, authors project a transmission rate of 1.74, 12,571 deaths, and a total of 1,205,515 people living with HIV. By 2025, with a target of 12,000 new HIV infections (a 69% decrease in HIV incidence), authors project a transmission rate of 0.98, 12,522 deaths, and a total of 1,220,615 people living with HIV. With a 90/90/90 framework by 2020 and a 95/95/95 framework by 2025, these epidemiologic targets would be feasible. Key programmatic milestones provide an ambitious, but important, pathway to reduce U.S. HIV incidence below 12,000 new infections by 2025. HIV incidence would decrease below mortality in 2025, marking a transition toward ending the HIV/AIDS epidemic. Such goals will require a sustained and intensified national commitment over the next decade.

A qualitative study of secondary distribution of HIV self-test kits by female sex workers in Kenya.

Promoting awareness of serostatus and frequent HIV testing is especially important among high risk populations such as female sex workers (FSW) and their sexual partners. HIV self-testing is an approach that is gaining ground in sub-Saharan Africa as a strategy to increase knowledge of HIV status and promote safer sexual decisions. However, little is known about self-test distribution strategies that are optimal for increasing testing access among hard-to-reach and high risk individuals. We conducted a qualitative study with 18 FSW who participated in a larger study that provided them with five oral fluid-based self-tests, training on how to use the tests, and encouragement to offer the self-tests to their sexual partners using their discretion. Women demonstrated agency in the strategies they used to introduce self-tests to their partners and to avoid conflict with partners. They carefully considered with whom to share self-tests, often assessing the possibility for negative reactions from partners as part of their decision making process. When women faced negative reactions from partners, they drew on strategies they had used before to avoid conflict and physical harm from partners, such as not responding to angry partners and forgoing payment to leave angry partners quickly. Some women also used self-tests to make more informed sexual decisions with their partners.

HIV risk perception and testing behaviours among men having sex with men (MSM) reporting potential transmission risks in the previous 12 months from a large online sample of MSM living in Germany

BackgroundHIV testing and serostatus awareness are essential to implement biomedical strategies (treatment as prevention; oral chemoprophylaxis), and for effective serostatus-based behaviours (HIV serosorting; strategic positioning). The analysis focuses on the associations between reported sexual risks, the perceived risk for HIV infection, and HIV testing behaviour in order to identify the most relevant barriers for HIV test uptake among MSM living in Germany.MethodsMSM were recruited to a nationwide anonymous online-survey in 2013 on MSM social networking/dating sites. Questions covered testing behaviours, reasons for testing decisions, and HIV risk perception (5-point scale). Additional questions addressed arguments in favour of home/ home collection testing (HT). Using descriptive statistics and logistic regression we compared men reporting recent HIV testing (RT; previous 12 month) with men never tested (NT) in a subsample not previously diagnosed with HIV and reporting ≥2 episodes of condomless anal intercourse (CLAI) with a non-steady partner of unknown HIV serostatus in the previous 12 months.ResultsThe subsample consisted of 775 RT (13 % of RT) and 396 NT (7 % of NT). The number of CLAI episodes in the last 12 months with non-steady partners of unknown HIV status did not differ significantly between the groups, but RT reported significantly higher numbers of partners (>5 AI partners: 65 vs. 44 %). While perceived risks regarding last AI were comparable between the groups, 49vs. 30 % NT were <30 years, lived more often in towns/villages <100,000 residents (60 vs. 39 %), were less out-particularly towards care providers-about being attracted to men (aOR 10.1; 6.9–14.8), more often identified as bisexual (aOR 3.5; 2.5–4.8), and reported lower testing intentions (aOR 0.08; 0.06–0.11).Perceived risks (67 %) and routine testing (49 %) were the most common testing reasons for RT, while the strong belief not to be infected (59 %) and various worries (41 %) and fears of testing positive (35 %) were predominant reasons of NT. Greater anonymity (aOR 3.2; 2.4–4.4), less embarrassment, (aOR 2.8; 1.9–4.1), and avoiding discussions on sexual behaviour (aOR 1.6; 1.1–2.2) were emphasized in favour of HT by NT.ConclusionsPerceived partner knowledge and reasons reflecting perceived gay- and HIV-related stigma predicted testing decisions rather than risk perception. Access barriers for testing should be further lowered, e.g. by making affordable HT available, addressing structural barriers (stigma), and emphasizing beneficial aspects of serostatus awareness.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-016-3759-5) contains supplementary material, which is available to authorized users.

Self-reported historic human immunodeficiency virus (HIV) testing in a Brazilian blood donor HIV case-control study.

There has been increased worldwide emphasis on the many benefits of human immunodeficiency virus (HIV) serostatus awareness for both infection prevention and improved treatment outcomes. Previous studies indicate that donors may use blood donation to be tested; the objectives of this analysis were to assess, among donors with previously undisclosed risk behavior in the 12 months before donation, the frequency of those who have previously been tested for HIV and the demographic and behavioral factors associated with such testing. In this secondary analysis from an HIV case-control study of blood donors in Brazil, we analyzed the response to the question, "Other than blood donation, have you ever been tested for HIV?" Demographic and disclosed risk behaviors associated with previous testing were determined. The study included 341 HIV-positive cases and 791 HIV-negative controls (1:2 case/control ratio). Overall, 31% of blood donors (40% of cases and 26% of controls) reported having been tested for HIV outside of blood donation. History of HIV testing varied according to sex, HIV status, and reported sexual risk behavior. Although it is encouraging that previous testing was more frequent in donors with acknowledged sexual risk behavior in Brazil, 60% still had not been tested for HIV outside of the blood donation setting. Educating donors on the importance of not using blood centers as a means to get tested for HIV in Brazil, especially if they engage in higher risk behaviors, and seeking alternate testing venues instead could improve the safety of donated blood.

Demographic Trends in New HIV Diagnoses in the U.S., 2009−2013

HIV testing is key to achieving the National HIV/AIDS Strategy goals. A new diagnosis metric evaluated whether testing services are reaching the remaining undiagnosed people living with HIV (PLWH), by subpopulation. Centers for Disease Control and Prevention surveillance data from 2008 to 2013 were obtained for: (1) new HIV diagnoses; (2) HIV prevalence; and (3) percentage of PLWH aware of serostatus. The number of new HIV diagnoses in a given year divided by the number of undiagnosed PLWH in the previous year was determined. Trends were evaluated by calculating net percentage change in this measure from 2009 to 2013 for all new diagnoses and stratified by subpopulation. Analyses were conducted during 2015-2016. The proportion of all undiagnosed PLWH who achieve serostatus awareness was 26.0%, 25.9%, 26.1%, 27.7%, and 30.4% from 2009 to 2013, respectively. The absolute net change was 4.3% (5.2% for men and 0.5% for women). There was an absolute net change of 5.0%, 3.1%, and 5.5% for the black, Hispanic, and men who have sex with men communities, respectively. An absolute net change >10% was observed only for those aged 13-24 years (10.9%) and ≥65 years (17.8%), and for men who inject drugs (11.7%). The proportion of undiagnosed PLWH who achieve serostatus awareness increased minimally from 2009 to 2013, especially for blacks, Hispanics, and men who have sex with men. Redirecting HIV testing efforts and funds to disproportionately affected communities is essential.

Peru's HIV care continuum among men who have sex with men and transgender women: opportunities to optimize treatment and prevention.

The HIV epidemic in Peru is concentrated in men who have sex with men (MSM) and transgender women (TW), who have an estimated prevalence > 10%, while the overall population prevalence remains < 1%. Because MSM and TW account for >60% of new infections, it is crucial to understand the full HIV continuum of care for these key populations. We performed a review of the peer-reviewed scientific and grey literature to determine the proportion of HIV-infected MSM and TW in Peru who are diagnosed, linked to and retained in care, are taking antiretroviral therapy (ART), and who have attained virologic suppression. Of the estimated 613,080 MSM and TW in Peru in 2015, approximately 63,981 are HIV-infected. Only 24.0% of HIV-infected MSM and TW are aware of their diagnosis, 15.6% are retained in care, 13.6% are on ART, and 12.0% have achieved adequate virologic control. The largest drop-off in the HIV care continuum occurs at the first step: diagnosis of HIV. Improving HIV serostatus awareness among MSM and TW is crucial to controlling Peru's HIV epidemic. In the era of 'treatment as prevention', understanding the full HIV care continuum may help guide efforts to curb transmission and reduce HIV-related morbidity and mortality.
