Background: The coronavirus disease 2019 (COVID-19) pandemic disrupted healthcare systems, posing risks for adolescents living with HIV (ALHIV) in resource-limited, high HIV-prevalence settings. These disruptions threatened antiretroviral therapy (ART) adherence, viral load suppression (VLS) and retention in care (RiC). Aim: This study aimed to compare treatment outcomes of ALHIV on ART in the Khayelitsha and Eastern Substructure (KESS) before and during the COVID-19 pandemic. Setting: The study was performed in KESS, Cape Town, South Africa. Methods: A retrospective cohort analysis was conducted among ALHIV aged 10-19 years receiving ART at public health facilities, pre-COVID-19 (before 01 March 2020) and during COVID-19 (01 March 2020-31 December 2021). Sociodemographic, clinical, and treatment data were analysed. Descriptive and inferential statistics compared outcomes and determined factors associated with VLS (< 1000 copies/mL) using SPSS v.30. Results: < 0.001). In multivariate analysis, higher CD4 count, and consistent ART adherence predicted VLS. Conclusion: Antiretroviral therapy adherence and VLS rates among ALHIV declined during COVID-19. Adolescent-centred healthcare delivery models are needed to ensure continuity of HIV treatment during public health emergencies. Contribution: This study provides local evidence on the pandemic's impact in a high-burden South African context. By quantifying declines in ART adherence, RiC, and VLS, it highlights ALHIV vulnerabilities and the need to strengthen adolescent-responsive, resilient healthcare systems.
