Overview

Cystic fibrosis (CF) is a rare autosomal recessive disease involving multiple organs, especially the lungs and digestive organs. It is most commonly seen in Caucasians. Only a few Chinese CF patients have been described in literature, taking into account the large population of China. The main objectives of this study are to accurately evaluate the prevalence of CF, the status of disease, the diagnosis and treatment, the quality of care, and the health related outcomes in China.
