Several classification systems are used in epidemiology, each serving different purposes:
ICD: The International Classification of Diseases, maintained by the WHO, is a globally used diagnostic tool for epidemiology, health management, and clinical purposes. ICF: The International Classification of Functioning, Disability, and Health focuses on the impact of diseases on daily living and functioning. DSM: The Diagnostic and Statistical Manual of Mental Disorders is used for classifying mental health conditions. NUTS: This European system classifies regions for statistical purposes and facilitates regional analysis.
