HIV disproportionately affects key populations (MSM, transgender people, sex workers and psychoactive substance users), who face greater social vulnerability and limited healthcare access. This study aimed at analyzing sexual orientation and gender identity and their association with sexual practices, sexually transmitted infections and psychoactive substance use among PrEP users. Method: A cross-sectional study was conducted between January 2018 and June 2021 with 736 Brazilian PrEP users from a health service in São Paulo. Sociodemographic data, sexual behaviors, STI history (past 3 months) and psychoactive substances use (past 3 months) were extracted from clinical records. The associations were analyzed using binomial logistic regression (p < 0.05). Results: Most of the participants were cisgender men (93.4%) and homosexual (84.8%), with a mean age of 34.9 years old. Condomless sex was reported by 98.5%, and 18.4% had some recent sexually transmitted infection, mainly syphilis. Psychoactive substance use was reported by 55.4%, especially marijuana, club drugs, erectile stimulants and poppers. Transgender and cisgender women were more likely to report sex work and crack use. Homosexual and bisexual participants had higher odds of using erectile stimulants. Conclusions: The study reveals key links between gender, sexual orientation and risk behaviors, highlighting the need for inclusive, targeted prevention. Full article

Adult entertainment work may be associated with increased vulnerability to sexually transmitted infections, particularly HIV. In Brazil, pre-exposure prophylaxis (PrEP) for HIV infection has been available through the Brazilian Unified Health System (SUS) since November 2017, representing a significant advancement in public sexual health policy. The objective of this study was to understand the individual and social determinants that promote PrEP use among adult entertainment workers. This was a cross-sectional, analytical, and quantitative study. A multivariate modeling approach was employed to identify factors independently associated with PrEP use. The study included 254 adult entertainment workers using oral PrEP through the SUS, predominantly young adults (141; 55.5%), SUS users (248; 97.6%), single (213; 83.9%), non-white (142; 55.9%), cisgender (148; 58.3%), and heterosexual (152; 59.8%). Factors independently associated with greater PrEP use included having adult entertainment as the main source of income (aPR: 2.69; 95% CI: 1.86–3.95), prior use of PEP (aPR: 2.49; 95% CI: 1.63–3.81), undergoing any type of health treatment (aPR: 1.56; 95% CI: 1.15–2.12), and having a history of STIs (aPR: 1.51; 95% CI: 1.10–2.08). Conclusion: PrEP use in this population was strongly influenced by structural and contextual factors, indicating that the availability of the technology alone does not ensure its effectiveness.

Despite the availability of pre-exposure prophylaxis (PrEP) in the United Kingdom (UK), uptake among men who have sex with men (MSM) remains inconsistent, signalling a persistent ‘PrEP Gap’. Empirical studies show the important role of psychosocial factors (e.g., stigma, identity, trust in science, and sexual behaviours) in PrEP acceptability and uptake. This study aimed to identify subgroups of MSM in the UK based on psychosocial predictors of PrEP acceptability. A cross-sectional survey of MSM (N = 500) was conducted between June and September 2023. Participants completed validated measures assessing identity resilience, internalised homonegativity, LGBTQ+ connectedness, trust in science, NHS perceptions, HIV stigma, PrEP self-efficacy, condom self-efficacy, sociosexual orientation, perceived HIV risk, and PrEP acceptability. Latent Profile Analysis (LPA) was used to identify distinct subgroups based on these psychosocial dimensions. Four psychosocial profiles were defined: (1) PrEP Ambivalent (15%); (2) PrEP Accepting (36.2%); (3) PrEP Hesitant (37%); and (4) PrEP Rejecting (11.8%). These profiles provide evidence for varied combinations of personal and structural factors influencing PrEP acceptability. PrEP acceptability among MSM in the UK is shaped by distinct psychosocial configurations, influenced by identity, stigma, trust, and perceived risk. These findings highlight the need for differentiated and targeted interventions for enhancing PrEP acceptability based on psychosocial profile. Audience segmentation strategies offer a promising pathway to bridge the awareness-to-engagement gap and address the nuanced barriers facing diverse subgroups within the MSM community. Full article

HIV/AIDS remains a global public health concern, with a high prevalence in sub-Saharan Africa. The President’s Emergency Plan for AIDS Relief (PEPFAR) initiatives, including preexposure prophylaxis (PREP) and postexposure prophylaxis (PEP), significantly reduced HIV infections in South Africa and Nigeria. The suspension of United States (U.S.) foreign aid may impact these preventive measures. Although some emergency aid programs were exempted, uncertainty persists, impacting global health initiatives, especially in South Africa and Nigeria. This study investigates the public health impacts of the United States (U.S.) government’s January 2025 suspension of U.S. foreign aid, focusing on its implications for HIV prevention initiatives, such as PREP and PEP, in South Africa and Nigeria. We comprehensively searched keywords such as PEPFAR, PREP, PEP, HIV infection in South Africa or Nigeria, antiretroviral (ARV) drugs, public healthcare impact, 2025 Trump’s foreign aid withdrawal, titles, and abstracts in Google Scholar, PubMed, and Web of Science. The search results were screened from 500 to 150 included articles based on their relevance and quality assessment for inclusion. The review unveiled that Nigeria maintained a continuous increase in HIV/AIDS-related deaths and new HIV infections from 1990, reaching the climax between 1999 and 2005, showing approximately 110,000 HIV/AIDS-related deaths and 200,000 new HIV infections. Notably, due to the PEPFAR intervention in Nigeria, an improved decrease in both HIV/AIDS-related deaths (45,000) and new HIV infections (75,000) was experienced from 2010 to 2023. South Africa experienced a rapid increase between 1990 and 2003 in both HIV/AIDS-related deaths and new HIV infections, reaching the climax around the early 2000s, with about 520,000 new HIV infections and 260,000 HIV/AIDS-related deaths in 2005. Furthermore, there was a continuous decline from 2005 onwards, with 50,000 HIV/AIDS-related deaths and 150,000 new HIV infections by 2023. Therefore, the suspension of this aid threatens disruptions in ARV therapy, possible increases in HIV transmission, shortages in PREP and PEP, the retrenchment of healthcare workers, the suspension of non-governmental organization activities, and the reversal of gains in vulnerable populations, reversing progress toward the 95-95-95 vision, increasing morbidity and mortality rates and financial strain on healthcare systems in these two countries. We recommend proactive measures, such as increased budget allocations for healthcare reforms, exploring local vaccine and health product development and diversifying funding sources in Nigeria, and implementing universal healthcare coverage for South Africans to mitigate the adverse consequences of aid withdrawal.

South Africa continues to experience a high HIV prevalence, necessitating innovative prevention strategies aligned with the UNAIDS 95-95-95 targets. Long-acting injectable pre-exposure prophylaxis (PrEP), such as cabotegravir (CAB-LA), offers a promising alternative to daily oral regimens. However, the perspectives of primary healthcare workers (PHCWs)—key implementers of this intervention—remain underexplored. This scoping review aims to systematically map existing literature on PHCWs’ knowledge, awareness, perceptions, barriers, facilitators, and implementation experiences related to injectable PrEP within the South African healthcare context. The review will follow the Arksey and O’Malley framework, enhanced by Levac et al., and will be reported following PRISMA-ScR guidelines. A comprehensive search will be conducted across PubMed, Scopus, CINAHL (EBSCOhost), Web of Science, and Google Scholar, without language or date restrictions. The search strategy will employ both controlled vocabulary (e.g., MeSH and CINAHL Subject Headings) and free-text terms. Studies meeting the inclusion criteria will be managed using EndNote X20 and appraised using the Mixed Methods Appraisal Tool (MMAT) 2018 version. Data will be synthesized thematically and presented narratively and in tabular form. By consolidating PHCWs’ perspectives, this review will identify implementation challenges, training needs, and systemic barriers, informing the development of context-specific strategies for PrEP rollout. The findings are expected to support the design of effective, culturally relevant educational interventions and guide policymakers in strengthening HIV prevention efforts in high-burden settings.

New STI/HIV diagnoses disproportionately impact U.S. Black cisgender women at higher rates compared to other racial/ethnic U.S. cisgender women. Biomedical HIV prevention interventions, such as HIV Pre-Exposure Prophylaxis, have demonstrated lower uptake among Black women. Given the need to further develop prevention interventions that meet the sexual and reproductive health (SRH) needs of U.S. Black women, this study aimed to identify and characterize condom use behaviors, sexual communication efficacy, and SRH healthcare utilization among sexually experienced young Black women (YBW) aged 18–25 (N = 206). Participants completed a self-administered questionnaire assessing sexual and conception vulnerability, sexual/reproductive healthcare utilization, and sexual communication efficacy. Descriptive statistics and univariate analyses were conducted to identify correlations in sexual and reproductive behaviors. The results showed that 32% of YBW used a condom during their last sexual encounter. Five distinct trends in condom use were identified, three of which included condomless vaginal/oral sex. YBW reported high levels of sexual communication with sexual partners and consistent engagement in sexual/reproductive health care, including abortion care. Young Black women have diverse sexual/reproductive health needs and require culturally responsive patient-centered clinical practices aimed at reducing STI/HIV rates and unintended pregnancies. Future research could examine healthcare providers’ understanding of Black women’s SRH priorities and assess how this knowledge aligns with or diverges from established clinical guidelines and best practices. Such inquiries could illuminate potential gaps in provider education and clinical practice, ultimately informing the development of care models that are both evidence-based and responsive to the lived experiences of young Black women.

Tennessee is in the southern region of the United States and has not yet fully benefitted from HIV pre-exposure prophylaxis (PrEP). Relatively little research has focused on pivotal roles of PrEP navigators. This study examined PrEP navigator perceptions of implementing long-acting injectable (LAI) PrEP in Tennessee. Semi-structured interviews with state-funded navigators were audio-recorded, transcribed, and systematically coded using a hierarchical system. Coded transcripts were aggregated, sorted, and analyzed using an iterative inductive/deductive qualitative approach. Using the Consolidated Framework for Implementation Research (CFIR), institutional, individual, and modifying factors to initiating and transitioning to LAI PrEP were identified. Most navigators initially had limited training and experience with LAI PrEP. Navigators reported systemic barriers associated with accessibility to LAI PrEP such as health insurance, pharmaceutical policies, and cost policies. While navigators noted the continued support of the state health department, strategies for circumventing individual and structural barriers are needed for universally implementing injectable PrEP.

In the United States (U.S.), Latina transgender women (LTW) are highly burdened by HIV and are prioritized for pre-exposure prophylaxis (PrEP). This study explored intersectional barriers and facilitators to PrEP uptake among LTW. Between February–November 2022, in-depth interviews were conducted with 27 LTW in the LITE Study. Participants were purposively sampled from 196 LTW in the cohort based on PrEP uptake (PrEP-naïve n = 8, PrEP-eligible and not user n = 5, current PrEP user n = 6, previous PrEP user n = 8). We conducted content analysis guided by a Modified Social Ecological Model and Intersectionality Framework. The mean age of participants was 32.3 (SD = 12.9). Themes were: (1) Intrapersonal: Medical distrust, acceptability of PrEP modalities, and concerns about long-term health; (2) Interpersonal: Mistreatment in healthcare, discrimination-related healthcare avoidance, difficulty finding trans-competent providers, language barriers, and shame and stigma; and (3) Structural: PrEP in the context of limited access to gender-affirming care and widespread silicone use, immigration status, economic marginalization, lack of community outreach, transphobia and anti-transgender legislative contexts, and xenophobia. This study found multilevel intersectional barriers influence PrEP uptake and persistence. Culturally tailored HIV prevention efforts are needed to address LTW-specific barriers, provide information on programs subsidizing PrEP, and implement policy change to ensure equitable PrEP access.

Introduction: This study aimed to assess, through health metrics and bibliometric analysis, the global research on attitudes and social stigma of people living with HIV/AIDS and to identify research findings, gaps, and future directions. Methods: A cross-sectional bibliometric study was conducted through a structured search in different databases. Fifteen thousand four hundred and ninety-six documents were found between 1981 and 2024. Results: 83.5% were original articles, and international co-authorship was 30.66%. Since 2000, there has been an increase in research on HIV/AIDS attitudes and social stigma. The United States is the most prolific country worldwide (n = 7837 publications; 50.5%), with the highest number of prolific institutions (n = 4/5), as well as the greatest influence and relevance in research (h-index 170). The most studied topics worldwide are social support and social psychology concerning homosexuality, middle age, and youth in people living with HIV/AIDS. There was no significant correlation between the volume of publications, countries’ income levels, and the most prolific geographic regions with adult HIV prevalence, overall HIV incidence and prevalence, or antiretroviral therapy coverage in people living with HIV (p > 0.05 for all cases). Conclusions: Over the past two decades, research has shifted from human rights, legal rights, and ethics to attitudes toward healthcare, with the recent interest in pre-exposure prophylaxis, gender minorities, and intersectional stigma. The absence of strong correlations between publications volume and global health HIV-related indicators underscores the necessity of translating evidence into actionable strategies to reduce stigma and improve health outcomes.

Background/Objective: HIV remains a significant public health issue in Poland, with many diagnoses occurring at advanced stages due to the limited access to diagnostic tools in primary healthcare (PHC). General practitioners are crucial for early detection, but barriers such as the absence of rapid testing in PHC settings hinder a timely diagnosis. This study evaluates primary care physicians’ knowledge of HIV diagnostics and pre-exposure prophylaxis (PrEP), focusing on their role in improving prevention and early detection. Material and Methods: This study used anonymous surveys distributed online and on paper to physicians in randomly selected primary care facilities across four Polish voivodeships. The data were analysed statistically to assess their knowledge, attitudes, and practices related to HIV diagnostics, rapid testing, and PrEP. Results: A total of 100 surveys were collected. A total of 83% of the physicians reported recommending HIV tests, although 17% had never done so, mainly among family medicine specialists. A total of 88% were aware of Voluntary Counselling and Testing Centres (VCTs), but 99% had never performed rapid HIV tests in their offices. Physicians with shorter professional experience (less than 10 years) demonstrated a significantly higher awareness of PrEP compared to that in those with longer experience (Fisher’s test p = 0.35). Conclusions: Primary care physicians play a crucial role in HIV prevention, but limited access to diagnostic tools and systemic support hampers their effectiveness. Targeted education and a comprehensive program for STI and HIV prevention are needed to improve prevention efforts and early detection. Full article

South Africa’s health system was affected by the various mitigation measures implemented to control the rapid spread of the COVID-19 pandemic. However, innovative interventions were introduced to ensure service continuity. This study sought to explore the perspectives of stakeholders regarding the pre-exposure prophylaxis (PrEP) innovative interventions implemented during the COVID-19 lockdown period among adolescent girls and young women (AGYW), as well as their successes and improvements. We selected and interviewed 12 PrEP stakeholders, including professional nurses, case managers, peer educators, and counselors from the TB HIV Care programme in the Dr. Kenneth Kaunda District, in the North-West Province. The qualitative questions explored (1) how PrEP services were disrupted during the lockdown period, (2) how the disruptions were managed, and (3) the challenges and successes of the innovative interventions implemented. The interviews were audio-taped, transcribed, and thematically analyzed through Tesch’s eight steps of analysis. The stakeholders confirmed that COVID-19 disruptions affected the provision of PrEP services in terms of recruitment, counseling, HIV testing, and adherence support offered in different community hotspots. Responding to these difficulties, alternative avenues such as social media platforms were implemented and used for service continuity. The themes that emerged were organized into the following two categories: PrEP services provided during and after the COVID-19 lockdown period, as well as the successes and challenges. The current study provides further insight into COVID-19, aiming to inform preparations for future pandemics. Innovative PrEP interventions alleviated COVID-19 disruptions in some settings and improved HIV services, but this was not the case in the selected study area. Full article

Attention to increasing pre-exposure prophylaxis (PrEP) use among cisgender Black women (CBW) in the southern United States (U.S.) is necessary to achieve national 2030 Ending the HIV Epidemic (EHE) goals. Qualitative exploration of CBW’s readiness to use PrEP is necessary to discern whether practical solutions to addressing PrEP uptake within this HIV-vulnerable population are feasible. Focus group discussions (n = 5) and key informant interviews (n = 3) in two EHE jurisdictions in Houston and Austin, Texas were used to explore how perspectives and lived experiences may serve as facilitators and/or barriers to PrEP readiness among 20 CBW. Codes highlighted facilitators and barriers to PrEP readiness. Facilitators involved positive experiences with the healthcare system, high perceived HIV vulnerability, and prioritizing PrEP as self-care. Barriers encompassed concerns with sexual relationship dynamics, mental health implications, and access to humane treatment within the healthcare system. High perceived vulnerability of HIV acquisition is related to an awareness that CBW may not know the entirety of their partner’s sexual activities. Findings indicate precursors of PrEP readiness and challenge the notion that CBW have low perceived vulnerability of acquiring HIV. Full article

Prescriptions for and use of pre-exposure prophylaxis (PrEP), an available and accessible HIV prevention strategy, remain low among cisgender Black women (CBW). Given PrEP is only available through a prescription from a licensed healthcare provider (HCP), there is a need to identify factors associated with HCP’s prescribing and/or referring PrEP to CBW. Qualitative methods (in-depth interviews) were used to examine factors shaping beliefs and behaviors among 12 HCPs that impact their willingness to prescribe or refer PrEP to CBW. Seven primary themes were identified during a thematic data analysis. The themes with the highest frequency of codes (fc) were the provider’s experience discussing sexual health (fc = 284), the provider approach to patient engagement (fc = 240), provider knowledge of PrEP (fc = 158), and the provider approach to determining PrEP eligibility (fc = 141). Findings indicate that prescribing and referral behaviors among HCPs can be influenced by their knowledge of PrEP; perceptions about PrEP for patients; comfort level in engaging/communicating with patients about PrEP; awareness of PrEP resources needed to improve PrEP access among patients; and patient–provider communication relative to sexual health, HIV vulnerability, and PrEP eligibility. Study findings illuminate how usual care practices contribute to gaps in PrEP access among CBW and highlight areas for intervention. Full article

Treatment as Prevention (TasP) and Pre-Exposure Prophylaxis (PrEP) are both widely recognized as essential biomedical tools to control HIV/AIDS. TasP calls for the immediate initiation of fully subsidized and supported antiretroviral therapy (ART) following HIV diagnosis. TasP effectively prevents progression to AIDS, and premature AIDS-related deaths among people living with HIV (PLWH), and simultaneously renders HIV non-transmissible, thus preventing onward HIV transmission. In addition, PrEP has proven effective against HIV transmission among high-risk individuals who are adherent to the regimen. PrEP traditionally consists of two antiretrovirals given orally as one pill daily: originally, tenofovir-DF plus emtricitabine (TDF-FTC), and later, tenofovir-AF (TAF) plus FTC (more recently, other options have become available, including long-acting parenteral formulations; however, these are still of limited availability). Over the last two decades, the province of British Columbia has rolled out TasP among all PLWH, and starting in 2018, PrEP was added as a strategy to reach individuals most at risk of acquiring HIV to further accelerate progress in addressing HIV/AIDS as a public health threat. Our “generalized TasP + focused PrEP” program proved to be synergistic (or multiplicative) as it relates to reducing the HIV effective reproduction number (${\mathrm{R}}_{\mathrm{e}}$). TasP lowers HIV incidence by reducing the pool of individuals able to transmit HIV, which is dependent on the extent of community plasma viral load (pVL) suppression. Meanwhile, PrEP reduces the number of potential new infections among those most susceptible to acquiring HIV in the community, independent of viral load suppression among PLWH. Our results strongly support widespread implementation of the combination of “generalized TasP + focused PrEP” strategy and underscore the importance of long-term monitoring of ${\mathrm{R}}_{\mathrm{e}}$ at a programmatic level to identify opportunities for optimizing TasP and PrEP programs. This approach aligns with the United Nations goal of “Ending HIV/AIDS as a pandemic by 2030”, both in Canada and globally. Full article

Background: Understanding the dynamics of HIV transmission in heterogeneous populations is crucial for effective prevention strategies. This study introduces the Risk Modulation Point (RMP), a novel threshold identifying where HIV transmission transitions from unsustainable spread to self-sustaining epidemic dynamics. Methods: Using a deterministic, risk-stratified compartmental model, we examined HIV transmission across populations stratified into 100–200 risk groups, each characterized by behavioral heterogeneity modeled through a power-law distribution. The model captures key features of HIV progression, with simulations conducted across high- (~20%), moderate- (~5%), and low (~0.2%)-prevalence regimes. Results: Our findings reveal universal patterns in HIV dynamics. The RMP marks a consistent threshold across scenarios, separating low-risk groups where transmission is minimal from higher-risk groups sustaining the epidemic. Logistic growth in HIV prevalence across risk groups, with sharp transitions near the RMP, was observed universally. The force of infection follows power-law scaling, directly reflecting the level and nature of risk behavior within each group. Importantly, the location of the RMP remains largely invariant to the underlying sexual risk distribution, population resolution, and mixing patterns, making it applicable across both generalized and concentrated epidemics. Conclusion: The RMP framework offers actionable public health insights. It identifies key populations and transition regions for targeted interventions such as antiretroviral therapy and pre-exposure prophylaxis. By tracking shifts in the RMP, it also serves as an early warning indicator for epidemic transitions, guiding resource allocation and monitoring. The focus of the model on intrinsic epidemic dynamics, excluding external interventions, highlights its utility in uncovering fundamental transmission patterns. This study bridges theoretical modeling and practical application, providing a flexible framework for understanding HIV and other stratified epidemics. The findings advance HIV modeling by revealing generic patterns that transcend specific contexts, supporting data-driven public health strategies. Full article
