The 2021 Conference on Retroviruses and Opportunistic Infections included advances in therapy for HIV as well as for SARS-CoV-2. Data presented on COVID-19 therapies included trials showcasing the use of monoclonal antibodies for prevention and treatment of COVID-19. Promising new data were presented on lenacapavir, an investigational HIV capsid inhibitor given as a subcutaneous injection every 6 months. Although encouraging data from settings across the globe reported achievement of 90-90-90 HIV care cascade targets, disparities exist in care engagement and viral suppression, particularly for people of color and young people with HIV. Several interventions were associated with improved care cascade outcomes. The COVID-19 pandemic has impacted HIV care engagement, but mitigation strategies can allow programs to continue to serve people with HIV during the pandemic. Studies examining the resistance patterns of existing antiretroviral therapy (ART) agents were presented, as were resistance mechanisms of novel agents such as lenacapavir and resistance patterns among individuals who seroconverted while on preexposure prophylaxis. Data from large observational cohorts were presented on patterns of ART uptake and trends in mortality and in virologic failure. Pertinent findings relating to pediatric and maternal health issues included data on dolutegravir-based ART in children and adolescents with HIV; safety and tolerability of dolutegravir-based ART in children and pregnant women; similarly high maternal viral suppression at 50 weeks postpartum in women receiving certain ART regimens; weight gain in pregnant women receiving dolutegravir plus tenofovir alafenamide/emtricitabine; and viral suppression with dolutegravir-based ART when started during the third trimester of pregnancy.
