: Introduction: We sought to characterize social and structural drivers of HIV vulnerability for transgender women (TGW) in Zimbabwe, where TGW are not legally recognized, and explore differences in vulnerability by feminine presentation. Methods: A secondary analysis was conducted with a sub‐sample of participants recruited from a 2019 respondent‐driven sampling survey that comprised men who have sex with men, TGW and genderqueer individuals assigned male sex at birth, from two cities in Zimbabwe. Survey questionnaires captured information related to socio‐demographics, sexual and substance use behaviours, and social and structural barriers to HIV services. Secondary analyses were restricted to participants who identified as female, transfemale or transwomen (236/1538) and were unweighted. Descriptive statistics were used to calculate sample estimates and chi‐square and Fisher's exact tests were used to assess differences in vulnerability by feminine presentation. Results: Among 236 TGW, almost half (45.3%) presented as feminine in the 6 months preceding the survey and 8.5% had ever used hormones to affirm their gender identities. Median age among TGW was 23 years (interquartile range: 20–26). Feminine presenting TGW in our sample had higher prevalence of arrest (15.9% vs. 3.9%), rejection by family/friends (38.3% vs. 14.0%), employment termination (11.2% vs. 3.9%), employment refusal (14.0% vs. 3.9%), denial of healthcare (16.8% vs. 2.3%), physical, sexual or verbal harassment or abuse (59.8% vs. 34.1%), alcohol dependence (32.7% vs. 12.4%), recent transactional sex with a male or TGW partner (30.8% vs. 13.3%) and recent non‐injection drug use (38.3% vs. 20.2%) than non‐feminine presenting TGW (all p‐value Conclusions: Findings suggest that TGW, particularly feminine presenting TGW, experience social and structural inequities which may contribute to HIV vulnerability. Interventions aimed at addressing inequities, including trans competency training for providers and gender‐affirming, psychosocial and legal support services for TGW, might mitigate risk., INTRODUCTION Transgender people, including transgender women (TGW), are disproportionately affected by HIV [1–3] and face distinct challenges accessing HIV prevention and treatment services. In 2021, the relative risk of acquiring [...]

: Introduction: The burden of HIV in sub‐Saharan Africa (SSA) remains unacceptably high, and disproportionately affects girls and women. While the introduction of oral HIV pre‐exposure prophylaxis (PrEP) in 2012 revolutionized HIV prevention, its effectiveness is dependent on user adherence and its implementation in SSA has faced numerous challenges. Patient‐level, interpersonal and structural barriers, including, for example, daily pill burden, side effects, lack of partner support, testing and disclosure, and costs have been found to reduce adherence to oral PrEP. Discussion: Long‐acting extended delivery (LAED) formulations for PrEP, such as injectable long‐acting cabotegravir (CAB‐LA) and dapivirine vaginal ring (DPV‐VR) are critical additions to the HIV prevention toolkit and are especially important for populations such as adolescent girls and young women (AGYW) and other key populations who remain at significant risk of HIV acquisition while facing substantial barriers to preventive services. These LAED formulations have been shown to result in better adherence and fewer side effects, with CAB‐LA being superior to oral PrEP in reducing the risk of HIV acquisition. They can be used to overcome user burden and adherence challenges. However, the successful rollout of the DPV‐VR and CAB‐LA may be hampered by issues such as a shortage of healthcare providers (HCPs), inadequate parenteral medication infrastructure, increased workload for HCPs, patient concerns, the price of the medications and the possibility of drug resistance. Conclusions: SSA must develop laboratory capabilities for monitoring patients on LAED formulations and enhance research on developing more non‐injectable LAED formulations. There is a need to train and retain more HCPs, implement task shifting, invest in healthcare infrastructure and integrate healthcare services. To reduce costs and improve availability, the region must advocate for patent license waivers for LAED formulations and procure drugs collectively as a region., INTRODUCTION The burden of HIV in sub‐Saharan Africa Despite major advances in HIV prevention and treatment, the global burden of HIV remains unacceptably high. Approximately 38 million people are currently [...]

Introduction: Zimbabwe is scaling up pre-exposure prophylaxis (PrEP) for key populations, including men who have sex with men (MSM) and transgender women (TGW). To assess implementation and inform HIV programming, we evaluated gaps in PrEP awareness, uptake and use, and correlates of awareness and uptake among a sample of MSM, TGW and genderqueer individuals (GQ) in Harare and Bulawayo, Zimbabwe. Methods: Respondent-driven sampling was used to recruit 1194 MSM and 344 TGW/GQ aged >18 to participate in a cross-sectionalsurvey assessing HIV-related outcomes in 2019. Consenting participants completed a questionnaire on sociodemographic information, sexualrisk practices and engagement in HIV services and underwent HIV testing. Descriptive statistics were used to assess the PrEP cascade. Multiple logistic regression models were used to identify factors associated with PrEP awareness and uptake among HIV-negative participants. Data were unweighted as the sample did not reach convergence on key estimates. Results: Among the 1167 HIV-negative participants, most (79.2%) were MSM compared to TGW/GQ (20.8%). Median age was 24 years. Overall, 45.8% were aware of PrEP and of those, 31.3% had ever taken PrEP. Most (71.1%) reporting never taking PrEP were willing to start PrEP; the main reasons for never starting PrEP included not knowing where to access it (24.8%) and fearing side effects (20.4%). Among those who had ever taken PrEP, 74.9% had taken PrEP in the last 6 months; of these, 42.4% had taken PrEP the day of or day preceding the survey. Side effects represented the most common (59.5%) reason for discontinuing PrEP. MSM (adjusted odds ratio [aOR]: 2.5, 95% confidence interval [CI]: 1.8-3.6) and TGW/GQ in Harare (aOR: 3.1, 95% CI: 2.1-4.7), and TGW/GQ in Bulawayo (aOR: 2.4, 95% CI: 1.1-5.3) had higher awareness of PrEP than MSM in Bulawayo. Overall, TGW/GQ were more likely to have ever taken PrEP compared to MSM (aOR: 1.6, 95% CI: 1.01-2.4). Conclusions: Findings emphasize the need for tailored interventions to promote PrEP among key populations. As HIV programs in Zimbabwe continue to expand PrEP services, these data, including barriers to starting and continuing PrEP, can inform strategies to address gaps along the PrEP cascade.

With the advent of global health challenges like the COVID-19 pandemic, wastewater surveillance has emerged as a crucial tool for the early detection and management of viral outbreaks. This review will explore the application of various modeling techniques that enable the prediction and understanding of virus concentrations and spread patterns in wastewater systems. It highlights the role of spatial analysis in mapping the geographic distribution of viral loads, providing insights into the dynamics of virus transmission within communities. The integration of GIS in wastewater surveillance will be explored, emphasizing the utility of such systems in visualizing data, enhancing sampling site selection, and ensuring equitable monitoring across diverse populations. The review will also discuss the innovative combination of GIS with remote sensing data and predictive modeling, offering a multi-faceted approach to understand virus spread. Challenges such as data quality, privacy concerns, and the necessity for interdisciplinary collaboration will be addressed. This review concludes by underscoring the transformative potential of these analytical tools in public health, advocating for continued research and innovation to strengthen preparedness and response strategies for future viral threats. This article aims to provide a foundational understanding for researchers and public health officials, fostering advancements in the field of wastewater-based epidemiology. [ABSTRACT FROM AUTHOR]

: Introduction: Tuberculosis (TB) causes one‐third of HIV‐related deaths worldwide, making TB preventive treatment (TPT) a critical element of HIV programmes. Approximately 16% of people living with HIV (PLHIV) on antiretrovirals in Zimbabwe are enrolled in the Fast Track (FT) differentiated service delivery model, which includes multi‐month dispensing of antiretrovirals and quarterly health facility (HF) visits. We assessed the feasibility and acceptability of utilizing FT to deliver 3HP (3 months of once‐weekly rifapentine and isoniazid) for TPT by aligning TPT and HIV visits, providing multi‐month dispensing of 3HP, and using phone‐based monitoring and adherence support. Methods: We recruited a purposive sample of 50 PLHIV enrolled in FT at a high‐volume HF in urban Zimbabwe. At enrolment, participants provided written informed consent, completed a baseline survey, and received counselling, education and a 3‐month supply of 3HP. A study nurse mentor called participants at weeks 2, 4 and 8 to monitor and support adherence and side effects. When participants returned for their routine 3‐month FT visit, they completed another survey, and study staff conducted a structured medical record review. In‐depth interviews were conducted with providers who participated in the pilot. Results: Participants were enrolled between April and June 2021 and followed through September 2021. Median age = 32 years (IQR 24,41), 50% female, median time in FT 1.8 years (IQR 0.8,2.7). Forty‐eight participants (96%) completed 3HP in 13 weeks; one completed in 16 weeks, and one stopped due to jaundice. Most participants (94%) reported “always” or “almost always” taking 3HP correctly. All reported they were very satisfied with the counselling, education, support and quality of care they received from providers and FT service efficiency. Almost all (98%) said they would recommend it to other PLHIV. Challenges reported included pill burden (12%) and tolerability (24%), but none had difficulty with phone‐based counselling or wished for additional HF‐based visits. Discussion: Using FT to deliver 3HP was feasible and acceptable. Some reported tolerability challenges but 98% completed 3HP, and all appreciated the efficiency of aligning TPT and HIV HF visits, multi‐month dispensing and phone‐based counselling. Conclusions: Scaling up this approach could expand TPT coverage in Zimbabwe., INTRODUCTION Tuberculosis (TB) is the second leading cause of death from an infectious disease, causing 1.6 million deaths in 2021 [1]. Despite the scale‐up of antiretroviral therapy (ART), people living [...]

: Introduction: Hazardous alcohol use (HAU), defined as a pattern of alcohol consumption that increases the risk of harmful consequences for the user or others, is associated with an elevated risk of human immunodeficiency virus (HIV) infection and poor health outcomes. We describe the association between people living with HIV (PLHIV) who report HAU and key HIV indicators. Gaps in current literature in estimating HAU on HIV outcomes at the regional level of Eastern and Southern Africa still exist and our analysis aims to address this issue. Methods: We used weighted pooled data (2015–2017) from the nationally representative Population‐based HIV Impact Assessments among adults who provided written consent aged 18–59 years from Eswatini, Malawi, Namibia, Tanzania, Zambia and Zimbabwe. We estimated differences in the prevalence of HIV infection and The Joint United Nations Programme on HIV and AIDS (UNAIDS) 90‐90‐90 indicators between PLHIV by HAU status using log‐binomial regression, stratified by sex. HAU was determined using the Alcohol Use Identification Test—Consumption. Results: Among the 9755 women and 4444 men who tested HIV positive, 6.6% of women and 21.8% of men engaged in HAU. Women who reported HAU were more likely to be HIV positive (adjusted prevalence ratio [aPR] = 1.31, 95% CI: 1.18–1.46) compared to those who did not report HAU. For the UNAIDS 90‐90‐90 targets, women who engaged in HAU were more likely to be unaware of their HIV‐positive status (aPR = 1.22, 95% CI: 1.01–1.47) and not on antiretroviral therapy (ART) (aPR = 1.73, 95% CI: 1.26–2.37). Men who engaged in HAU were more likely to be unaware of their HIV‐positive status (aPR = 1.56, 95% CI 1.39–1.76) and not on ART (aPR = 1.72, 95% CI: 1.30–2.29). No difference in viral load suppression, defined as Conclusions: PLHIV who engage in HAU were more likely to have suboptimal outcomes along the HIV care continuum when compared to those who did not engage in HAU. Targeted interventions, such as alcohol screening for HAU in HIV testing and treatment settings and HIV prevention efforts in alcohol‐based venues, may help countries reach HIV epidemic control by 2030., INTRODUCTION As of 2020, Eastern and Southern Africa (ESA) account for approximately 20.7 million people living with human immunodeficiency virus (PLHIV), resulting in 55% of all infections globally and 44% [...]

Introduction: The global target for 2020 is that [greater than or equal to]90% of people living with HIV (PLHIV) receiving antiretroviral therapy (ART) will achieve viral load suppression (VLS). We examined VLS and its determinants among adults receiving ART for at least four months. Methods: We analysed data from the population-based HIV impact assessment (PHIA) surveys in Eswatini, Lesotho, Malawi, Zambia and Zimbabwe (2015 to 2017). PHIA surveys are nationally representative, cross-sectional household surveys. Data collection included structured interviews, home-based HIV testing and laboratory testing. Blood samples from PLHIV were analysed for HIV RNA, CD4 counts and recent exposure to antiretroviral drugs (ARVs). We calculated representative estimates for the prevalence of VLS (viral load Results: We included 9200 adults receiving ART of whom 88.8% had VLS and 11.2% had NVL including 8.2% who experienced VF and 3.0% who interrupted ART. Younger age, male sex, less education, suboptimal adherence, receiving nevirapine, HIV non-disclosure, never having married and residing in Zimbabwe, Lesotho or Zambia were associated with higher odds of NVL. Among people with NVL, marriage, female sex, shorter ART duration, higher CD4 count and alcohol use were associated with lower odds for VF and higher odds for interrupted ART. Many people with VF (44.8%) had CD4 counts Conclusions: Countries are approaching global VLS targets for adults. Treatment support, in particular for younger adults, and people with higher CD4 counts, and switching of people to protease inhibitor- or integrase inhibitor-based regimens may further reduce NVL prevalence.
