Introduction:The COVID-19 pandemic has disrupted access to critical health services, resulting in diminished gains in HIV epidemic control. This review assesses the magnitude of the impact that the COVID-19 pandemic has had on HIV services for adolescents.Methods:PEPFAR Monitoring, Evaluation, and Reporting programmatic data were analyzed from across 16 USAID-supported adolescent care and treatment programs for fiscal year 2020 (FY20; October 2019–September 2020). Descriptive statistics were used to calculate absolute number and percent change between the pre-COVID-19 (Quarters 1–2; October 2019–March 2020) and COVID-19 periods (Quarters 3–4; April 2020–September 2020) for clinical cascade indicators. All analyses were conducted in Microsoft Excel.Results:The number of HIV tests conducted during COVID-19 decreased by 21.4% compared with pre-COVID-19, with a subsequent 28% decrease in adolescents identified living with HIV. The rate of proxy linkage to antiretroviral therapy increased between periods, from 86.9% to 90.4%. There was a 25.9% decrease in treatment initiations among adolescents during COVID-19. During FY20, viral load coverage rates for adolescents dropped from 81.6% in FY20Q1 to 76.5% in FY20Q4, whereas the rates of viral load suppression for adolescents increased from 76.1% in FY20Q1 to 80.5% in FY20Q4.Conclusion:There was a substantial decrease in case-finding, treatment initiations, and viral load coverage rates for adolescents supported in USAID/PEPFAR programs during the COVID-19 pandemic. Additional health systems adaptations and strategies are required to ensure adolescents have continued access to HIV services during pandemic disruptions.
