Abstract
Long COVID, or post-acute sequelae of SARS-CoV-2 infection, reports to affect a significant proportion of COVID-19 survivors, leading to persistent and multi-organ complications. This review examines the epidemiology, symptoms of long COVID complications, including cardiac, hematological, vascular, pulmonary, neuropsychiatric, renal, gastrointestinal, musculoskeletal, immune dysregulation, and dermatological issues. By synthesizing the latest research, this article provides a comprehensive overview of the prevalence and detailed pathophysiological mechanisms underlying these complications. The purpose of this review is to enhance the understanding of diverse and complex nature of long COVID and emphasize the need for ongoing research, seeking to support future studies for better management of long COVID.
