Final answer:
The classification of disease, such as by the World Health Organization's International Classification of Diseases, allows for easy comparison, prediction of symptoms, identification of causal organisms, and the determination of appropriate therapeutic approaches, thereby improving understanding and management of diseases.
Step-by-step explanation:
The classification of disease allows for several things including easy comparison of diseases, which facilitates a deeper understanding of diseases' genetics and susceptibility to drugs.
It also enables prediction of disease symptoms, understanding of vectors for gene therapy, identification of causal organisms, and determination of appropriate therapeutic drugs. Additionally, it helps in the determination of a disease's pedigree, in conducting genetic analyses such as producing recombinants, and in detecting extracellular genes using techniques like FISH. The International Classification of Diseases (ICD) integrates disease classification with clinical practice and public health policy to track and monitor diseases effectively, contributing to global health and epidemiology.
