CROI 2023: Acute and Post-Acute COVID-19.

Abstract

Studies of acute and post-acute COVID-19 were presented at the 2023 Conference on Retroviruses and Opportunistic Infections (CROI). Early treatment with ensitrelvir, a novel protease inhibitor, hastened viral clearance and symptom resolution during coronavirus disease 2019 (COVID-19) and appeared to reduce the prevalence of long COVID symptoms. The development of novel agents against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including those with broader sarbecovirus activity such as anti-angiotensin-converting enzyme 2 monoclonal antibodies, is underway. A growing understanding of the pathophysiology of long COVID has provided several potential therapeutic targets for individuals experiencing this condition. Efforts to understand COVID-19 in people with HIV have led to novel insights into the biology and natural history of SARS-CoV-2 coinfection in this vulnerable subpopulation. These and other studies are summarized herein.
