AI Article Synopsis
- - The Ending the HIV Epidemic (EHE) initiative seeks to cut new HIV infections by 90% over 10 years, though the necessary intervention intensity for local areas isn't fully understood.
- - A study used a model to project the impact of various HIV interventions in 32 major cities, finding that even modest increases in testing and treatment could significantly decrease new infections.
- - The results showed that while substantial reductions in HIV cases are possible, achieving EHE's ambitious goals will require significant resources and efforts, especially targeting specific high-risk populations.
Article Abstract
Background: The Ending the HIV Epidemic (EHE) initiative aims to reduce incident HIV infections by 90% over a span of 10 years. The intensity of interventions needed to achieve this for local epidemics is unclear.
Objective: To estimate the effect of HIV interventions at the city level.
Design: A compartmental model of city-level HIV transmission stratified by age, race, sex, and HIV risk factor was developed and calibrated.
Setting: 32 priority metropolitan statistical areas (MSAs).
Patients: Simulated populations in each MSA.
Intervention: Combinations of HIV testing and preexposure prophylaxis (PrEP) coverage among those at risk for HIV, plus viral suppression in persons with diagnosed HIV infection.
Measurements: The primary outcome was the projected reduction in incident cases from 2020 to 2030.
Results: Absent intervention, HIV incidence was projected to decrease by 19% across all 32 MSAs. Modest increases in testing (1.25-fold per year), PrEP coverage (5 percentage points), and viral suppression (10 percentage points) across the population could achieve reductions of 34% to 67% by 2030. Twenty-five percent PrEP coverage, testing twice a year on average, and 90% viral suppression among young Black and Hispanic men who have sex with men (MSM) achieved similar reductions (13% to 68%). Including all MSM and persons who inject drugs could reduce incidence by 48% to 90%. Thirteen of 32 MSAs could achieve greater than 90% reductions in HIV incidence with large-scale interventions that include heterosexuals. A web application with location-specific results is publicly available (www.jheem.org).
Limitation: The COVID-19 pandemic was not represented.
Conclusion: Large reductions in HIV incidence are achievable with substantial investment, but the EHE goals will be difficult to achieve in most locations. An interactive model that can help policymakers maximize the effect in their local environments is presented.

Community health workers (CHWs) play a significant role in supporting health services delivery in communities with few trained health care providers. There has been limited research on ways to optimize the role of CHWs in HIV prevention service delivery. This study explored CHWs' experiences with offering HIV prevention services [HIV testing and HIV pre- and post-exposure prophylaxis (PrEP and PEP)] during three pilot studies in rural communities in Kenya and Uganda, which aimed to increase biomedical HIV prevention coverage via a structured patient-centered HIV prevention delivery model.

Introduction: This qualitative study examined adolescents' first experiences with HIV testing.
Methods: Data were collected from April 2018 to October 2020 as part of an HIV prevention and sex education intervention; SGM adolescents ( = 175) answered open-ended questions regarding experiences with their first HIV test and advice for other adolescents seeking HIV testing. Data were analyzed through inductive content analysis.

Introduction: Adolescent girls and young women (AGYW) in Kenya have low pre-exposure prophylaxis (PrEP) initiation rates in part due to stigmatizing interactions with health care providers. Our recent randomized clinical trial of a standardized patient actor (SP) training intervention for providers found higher quality PrEP delivery at intervention sites, however it was unclear whether improved service quality improved PrEP initiation.
Methods: This analysis used routine records from facilities participating in the randomized trial which aimed to improve provider communication and adherence to Kenyan guidelines when offering PrEP to AGYW.

Introduction: Oral pre-exposure prophylaxis (PrEP) is a priority intervention for scale-up in countries with high HIV prevalence. Policymakers must decide how to optimise PrEP allocation to maximise health benefits within limited budgets. We assessed the health and economic impact of PrEP scale-up among different subgroups and regions in western Kenya.

The US faces substantial demographic and geographic disparities in both HIV burden and access to pre-exposure prophylaxis (PrEP), an effective strategy to prevent HIV acquisition. Long-acting cabotegravir (CAB) is a novel, injectable PrEP option which demonstrated superior reduction in risk of HIV acquisition compared to daily-oral PrEP in the HPTN083 trial. We modelled the impact of increased PrEP initiations and the introduction of long-acting CAB on HIV incidence among men who have sex with men (MSM) in Atlanta, Georgia, a population with a high burden of HIV.
