Necrotizing fasciitis (NF) is a disease characterized by severe infection of the skin and its underlying soft tissues as the initial symptom. NF is known for its difficulty in early diagnosis and rapid progression. If not treated promptly, NF can quickly evolve into systemic infection, sepsis, and multiple organ failure, and it may even lead to patient death. Currently, many controversies and challenges remain in clinical practice for the diagnosis and treatment of NF. To promote the standardization of NF diagnosis and treatment, Chinese Burn Association, Editorial Board of the Chinese Journal of Burns and Wounds, and Burn Medicine Branch of China International Exchange and Promotion Association for Medical and Health Care, based on the latest relevant guidelines, literature, and clinical practice experience and in accordance with the principles of evidence-based medicine, have jointly developed the Consensus on the Diagnosis and Treatment of Adult Necrotizing Fasciitis (2025 Edition) through repeated discussion and voting. This consensus aims to provide scientific and standardized guidance for clinical diagnosis and treatment.
