Disease classification is the systematic categorization of diseases based on various criteria, such as their causes, symptoms, and affected body systems. This process helps healthcare professionals understand and communicate about diseases more effectively. Common classification systems include the International Classification of Diseases (ICD), which is used globally to standardize disease identification and reporting. By organizing diseases into specific categories, classification aids in diagnosis, treatment planning, and research. It also facilitates public health monitoring and epidemiological studies. Accurate disease classification is essential for improving patient care and advancing medical knowledge, ultimately leading to better health outcomes for individuals and populations.
