Abstract: At present, our country has entered the routine control stage of the COVID-19 epidemic. However, “long COVID” associated with COVID-19 may present with multi-system symptoms, leading to enduring effects and introducing new challenges to global public health. In China, consensus is lacking on the diagnosis, treatment, follow-up, and multidisciplinary management of long COVID syndrome. Progress in related diagnostic and therapeutic efforts primarily relies on the collective experiences of various disciplines and hospitals. This consensus is rooted in clinical and foundational research data on long COVID syndrome gathered from both domestic and international sources, supplemented by evidence from evidence-based medicine. It comprehensively addresses aspects such as epidemiology, definition, clinical manifestations in various systems, examinations, diagnosis, treatment, follow-up, and management strategies of long COVID syndrome. We distill 16 recommendations and hope to provide theoretical foundations and practical references to guide the accurate assessment and management of long COVID syndrome in clinical practice.
