Progress in the Pathogenesis of Pulmonary Fibrosis After Viral Pneumonia

Abstract

Viral pneumonia is the main cause of adult infection and death. The mild symptoms of this kind of disease are self-limiting, but it is easy to cause other serious diseases and lead to death. Through the investigation of relevant pathological literature and imaging literature, we can know that, In our clinical work, many patients with COVID-19 or other viral pneumonia have left fibrous words after improvement "The data shows that the PPF of patients with severe pneumonia caused by COVID-19 infection is 100% when they are discharged from hospital. Some patients will retain corresponding fibrosis changes after suffering from the disease, which will directly affect the pulmonary function and quality of life of patients. However, at present, China is not clear about the pathogenesis of pulmonary fibrosis caused by the disease. This article mainly focuses on pulmonary fibrosis after viral pneumonia inflammation To analyze the progress of research on pathogenesis of lung injury, explore the epidemiological characteristics of pulmonary fibrosis in patients with severe viral infection, and form the pathogenesis of lung injury based on relevant pathological basic research, so as to provide diagnostic ideas and basis for the follow-up treatment of the disease in China.
